Answer:
As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase .
Solid → Liquid: Melting or fusion
Solid → Gas: Sublimation

What is the measure of angle coa? 140° 150° 160° 170°.
Answer:
160
Explanation:
edge 2021
The measure of angle COA will be 160°. Option C is correct. Center angle theorem is the base of the given problem.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D shapes.
The measure of an angle formed by an arc of a circle with any point on the circumference of that circle is half the angle formed by that arc at the center of the circle.
The angle formed by arc AC at the center, will be twice as large. Therefore,
∠AOC = 2∠ABC
∠AOC = 2(80°)
∠AOC = 160°
As a result, the center angle AOC is 160 degrees.

What mass of glucose (C6H12O6) should be dissolved in 10. 0 kg of water to obtain a solution with a freezing point of -4. 2 ∘C?.
Answer:
4.1kg
Explanation:
I dont kwon but it was ok in the test
The mass of glucose dissolved in the solution is obtained as 4.734 Kg.
We know that;
ΔT = K m i
ΔT = Freezing point depression
K = freezing constant = 1.86 °C/m
m = molality of solution
i = Van't Hoff factor = 1 (molecular solution)
To find the freezing point depression;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Since freezing point of water = 0°C
Freezing point depression = 0°C - (-4. 2 ∘C) = 4. 2 ∘C
The molality of the solution is obtained as follows;
m = ΔT/K i
m = 4. 2 ∘C/ 1.86 °C/m × 1
m = 2.63 m
Molality = number of moles/mass of solvent in Kg
Number of moles = mass/molar mass =
Molar mass of glucose = 180 g/mol
Let the mass of solute be m
2.63 = m/180/10
2.63 = m/1800
m = 2.63 × 1800
m = 4734 g or 4.734 Kg

Answer:
I don't know answer what
The partial pressure of c₂h₂ is25 atm.
What is partial pressure?When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.
Partial pressures can be calculated in one of two ways:
To determine the individual pressure of each gas in a mixture, use PV = nRT. Determine the proportion of pressure from the total pressure that may be assigned to each individual gas by using the mole fraction of each gas.When there is a combination of two or more gases in a given volume, the pressure created by each individual gas in the mixture is expressed using the phrase partial pressure.
The partial pressures of the individual gases make up the total pressure of the gas combination. P1 + P2 + P3 = Ptot = Pi

In triangle def, cg = (x + 5) units and dg = (3x - 2) units. [figure may not be drawn to sacle] what is dg? 12 units 17 units 34 units 51 units.
The length of the segment DG is 34 units
How to determine the length DG?The attached figure represents the missing information in the question
The point G is the centroid of the triangle.
This means that:
CG : DG = 1 : 2
Express as fraction
CG/DG = 1/2
Multiply both sides by 2
DG = 2 * CG
Substitute the given parameters:
3x - 2 = 2 *(x + 5)
Expand
3x - 2 = 2x + 10
Evaluate the like terms
x = 12
Recall that:
DG = 3x - 2
So, we have:
DG = 3 * 12 - 2
Evaluate
DG = 34

Which features do most stratovolcanoes and cinder cone volcanoes have in common?.
shield volcanoes from very large gently sloped mounds from effusive eruption
Both stratovolcanoes and cinder cone volcanoes have steep sides and violent eruptions. The correct option is B.
What is a volcano?An opening in the crust of a planet or moon known as a volcano allows molten rock, heated gases, and other things to erupt.
The steep, conical-shaped strato-volcanoes are created by the alternating ash and lava deposits. This type of volcano's magma is made up of bubbles and has a high silica concentration.
A stronger force is applied from the bottom towards the surface after the gases in these bubbles are released. As a result, they are extremely explosive and produce large-scale material eruptions. Take Mount St. Helens, for instance.
The simplest volcanoes have steep sides and are called cinder cones. They are constructed from the substances and partially hardened lava spewed from the volcano's vents.
Due to the power of the gas and the molten lava that have gathered near the vent, eruptions are frequently explosive. Consider the drug Paricutin.
Thus, the correct option is B.
