Thermal Properties Of Matter
Test Description: Checking your conceptual understanding about thermal properties of matter.
Instructions: Answer all questions to get your test result.
1) When heat is supplied to a body,
A
the particles in the body move or vibrate faster.
B
there is an increase in the internal energy of the body.
C
there is always an increase in the temperature of the body.
D
there is an increase in bonding between the particles.
2) The increase in temperature when heat is supplied to a body can be explained by
A
a decrease in the average speeds of the particles in the body.
B
an increase in the average kinetic energy of the particles in the body.
C
a decrease in the internal energy of the particles in the body.
D
an increase in the average kinetic energy of the particles in the body.
3) Specific heat capacity is defined as
A
the amount of energy required to change a substance from one phase to another.
B
the amount of energy required to raise the temperature of a unit mass of a substance by 1°C.
C
the amount of energy required to change a unit mass of a substance from the liquid to the gaseous state.
D
the amount of energy required to raise the temperature of a substance by 1°C.
4) Why does a pure substance melt at a constant temperature?
A
All pure substances melt at 0°C.
B
The heat absorbed during melting is used to increase the kinetic energies of the particles, and not the temperature of the
C
The heat absorbed during melting is used to break the bonds between the particles.
D
Negligible (i.e. very little) heat is absorbed during this process.
5) The specific latent heat of fusion of ice is 3.4 × 105 J kg–1. Explain what this means.
A
The amount of energy needed to boil some water is 3.4 × 105 J.
B
The amount of energy needed to melt a unit mass of ice is 3.4 × 105 J.
C
The amount of energy needed to boil a unit mass of water is 3.4 × 105 J.
D
The amount of energy needed to melt a piece of ice is 3.4 × 105 J.
6) The rate of evaporation is affected by several factors. Which statement describes one of the factors appropriately?
A
A smaller exposed area increases the rate of evaporation.
B
Higher air humidity increases the rate of evaporation.
C
A lower surrounding temperature increases the rate of evaporation.
D
A higher altitude (height above sea level) increases the rate of evaporation.
7) A beaker of water is cooled from 90 °C to 30 °C. What will happen to the water molecules?
A
The water molecules contract and move slower than before.
B
The water molecules gain kinetic energy and move faster than before.
C
The water molecules expand and move faster than before.
D
The water molecules gain kinetic energy and move faster than before.
8) A substance consists of particles that are close together and sliding past each other at random. The average speed of the particles is not increasing. Which statement best describes the substance?
A
A solid being melted.
B
A liquid being heated.
C
A solid being heated.
D
A liquid being boiled.
9) A liquid is heated till it boils. The boiling point of the liquid is 80°C. Which of the following statements describe what happens if the liquid continues to be heated strongly as it boils?
A
The temperature of the liquid increases to 100°C.
B
The temperature of the liquid remains at 80°C, as there is no change in temperature during boiling.
C
The temperature of the liquid remains at 80°C, as the temperature cannot be increased beyond 80°C.
D
The temperature of the liquid drops below 80°C, as evaporation takes place and cools the liquid.
10) Which of the following explains the increase in temperature when heat is supplied to a body?
A
An increase in the average kinetic energy of the particles in the body.
B
A decrease in the average speeds of the particles in the body.
C
A decrease in the internal energy of the particles in the body.
D
An increase in the average spacing of the particles in the body.
