Answer:

Temperature remains constant while all of a solid is converted to a liquid.

When a solid is converted to a liquid, heat is absorbed.

Explanation:

During a phase change, the temperature of the system remains constant. Recall that latent heat is defined as heat that causes a change of state without a corresponding rise in temperature of the system.

When a solid is converted to a liquid, latent heat of fusion is involved hence the temperature of the system remains constant throughout the process.

Similarly, heat is absorbed as intermolecular forces are broken up and the would converts to liquid.

Explanation:

Answer:The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe=hf−BE KE e = h f − BE , where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

Explanation:

The maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light is 4.66eV.

Kinetic energy is defined as is a form of energy that an object and particle has by the reason of its movement.

It is also defined as the measure of the work that an object does by the virtue of its motion.

Kinetic energy can be expressed as

KE = 1/2 mv²

KE = hc / ∧

KE = 6.63 x 10⁻³⁴ x 3 x 10⁸ / 267

KE = 7.45 x 10⁻¹⁹ J

The charge on electrons 1.6 x 10⁻¹⁹ C

So, Maximum kinetic energy = 7.45 x 10⁻¹⁹ / 1.6 x 10⁻¹⁹

                                                = 4.66 eV

Thus, the maximum kinetic energy of an ejected electron if silver metal is irradiated with 224 nm light is 4.66eV.

ANTHROPOLOGY, SOCIOLOGY AND POLITICAL SCIENCE.

ANTHROPOLOGY; This is the study of human kinds in all times and places,it also entails humanistic study which includes our prehistoric origins and contemporary human diversity as well as topics like social change,globalization,human origin and the world history.

The activities that shows the nature and goals of anthropology includes;

- Looking at ones own culture in a more objective way like an outsider.

- Discovering the things that make people more different from one another.

- Producing new theories and knowledge about human home and their behaviors.

- Discovering/finding out what all people have in common.

There are four fields of anthropology; Linguistic anthropology, Biological anthropology, Archeology and cultural anthropology.

SOCIOLOGY; This is the scientific study of human civilization.

It is systemic and studies of groups and societies that people build

and the effect these have on their behavior.

Sociology greatly focuses on various social connections,

structures, organizations, processes and institutions.

The activities that show the goals and nature of sociology includes;

- Broadening our familiarity on facts about sociology.

- Critically studying the nature of humanity.

- Exposing our minds to the diverse perspectives on attaining the truth.

- Obtaining possible theories about the society.

- Understanding and appreciating that all things in the society are interdependent with each other.

Sociology brings together inputs that are composed of frequent forms and manners,they include; view points, consolidated values, attitudes and the norms of social institutions.

The different branches of sociology are; social psychology,social organisation, applied sociology, population studies, sociological theory and research,human ecology,social change.

POLITICAL SCIENCE; This is a discipline in academics that deals with the study of political processes, institutions, governments and behaviors of people.

It studies the complex behaviors of the people in power, various political actors, such as the government administration, opposition ad the subjects which are the masses.

Anthropology, sociology and political science are areas of social science, whose main objective is to study society in historical, social and cultural contexts.

Therefore, the social sciences seek to analyze and understand man through society, culture, economy and politics, with the aim of contributing to the development of a more egalitarian society with a better quality of life.

Answer : The correct option is (A) 51.0 mL

Explanation :

As we know that water displaced is equal to the volume of sphere.

Now we have to determine the volume of sphere.

Formula used:

Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]

where,

r = radius of sphere

Given:

Diameter of sphere = 4.6 cm

Radius of sphere = [tex]\frac{Diameter}{2}=\frac{4.6cm}{2}=2.3cm[/tex]

So,

Volume of sphere = [tex]\frac{4}{3}\times 3.14\times (2.3cm)^3[/tex]

Volume of sphere = [tex]50.94cm^3\approx 51.0 cm^3[/tex]

Water displaced = Volume of sphere = [tex]51.0 cm^3[/tex]

We know that:

[tex]1cm^3=1mL[/tex]

So,

Water displaced = 51.0 mL

Therefore, the correct option is (A) 51.0 mL

Answer:

A. 51.0 mL

Answer:

The water in the 75 mL beaker will cool down more rapidly then the water in the 500 mL beaker.

Explanation:

The scale of an object influences the object's properties. For example, the water in a small beaker loses heat more rapidly than the water in a large beaker. This is because heat loss decreases as volume increases. As the scale of a beaker increases, its volume increases. Therefore, the larger the beaker, the slower the water inside the beaker will cool.

Answer:

C) 2 H2(g) + O2 (g) 2 H2O (l) AH° = -571.6

kJ/mol

Explanation:

The magnitude of heat released in an exothermic reaction is shown by the magnitude of the change in enthalpy.

The more negative the enthalpy change of the reaction, the more the heat released by the process.

Hence,  2 H2(g) + O2 (g) 2 H2O (l) AH° = -571.6 kJ/mol has the most negative value of enthalpy change hence the greatest amount of heat is released in this reaction.

The reaction which would produce the largest amount of heat per mole of hydrogen is; Choice C: 2H2(g) + O2 (g). ===> 2 H2O (l) AH° = -571.6

AH° = -571.6kJ/mol.

According to the question;

It is evident that all the reactions are exothermic; the reactions release heat.

In this scenario; the reaction that would produce the largest amount of heat per mole of hydrogen is Choice C: 2H2(g) + O2 (g) =====> 2 H2O (l) AH° = -571.6 kJ/mol

An element is made of one type of  atom, while a compound is two or

more types of atoms combined.

Explanation:

An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.

Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.

As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

Answer:

1.273 atm

Explanation:

We are given:

P1 = 1 atm                         P2 = x atm

T1 = 20 degree celsius or 293 k        T2 = 100 degree celsius OR 373 k

Since the volume remains constant, we don't have to talk about that

From the Gas equation:

PV = nRT

Since  number of moles (n) , Universal gas constant (R) , Volume of the gas (V) are constants

P / T = k   (where k is a constant)

Hence we can say that P1 / T1 = k --------------(1)

Also, P2 / T2  = k -------------------------------------(2)

where k is the same constant

From (1) and (2):

P1 / T1 = P2 / T2

Now, plugging the values in this equation

1 / 293  = x / 373

x = 373 / 293

x = 1.273 atm

Therefore, the pressure of CO2 after increasing the temperature to 100 degree celsius is 1.273 atm

Answer is A.

Explanation:

Answer:

Explanation:

(1) In the IV solution, the solute here is the NaCl salt and the solvent is the liquid (water) the salt is dissolved in.

(2) If the NaCl is replace with water, the water content will become hypotonic to the red blood cells as there would be less solute in the solution than in the cell's cytosol. This also means there is more water in the solution than in the cell's cytosol.

(3) Because the water is hypotonic to the red blood cells (as described in (2) above), the net movement of water will be into the cell.

(4) If the movement of water is allowed to continue as described in (3) above (i.e if 0.9% NaCl in the solution is replaced with pure water instead and waited), the cell will rupture which can lead to cell lysis or cytolysis.

NOTE: An isotonic solution describes when there is the same amount of solute in the cell and the solution outside the cell hence there is little or no movement of water.
