Question

1. Which of the following is a direct cause of a substance’s temperature increase? (1 point)
Energy is removed from the particles of the substance.
Kinetic energy is added to the particles of the substance.
The number of atoms and molecules in a substance changes.
The volume of the substance decreases.
2. As the temperature of a substance increases, its volume tends to increase due to (1 point)

thermal equilibrium.
thermal energy.
thermal expansion.
thermal contraction.

Answer 1

1. Kinetic energy is added to the particles.
2. Thermal expansion.

Answer 2

can you help with some more please?

Answer 3

Well. Temperature, as you may know, is the movement of the particles in a substance. That's why kinetic energy means. When particles move fast it means the temperature is high, and when they are still it means they have low temperature.

Answer 4

3. Energy transferred as heat occurs between two bodies in thermal contact when they differ in which of the
following properties? (1 point)
mass
specific heat
density
temperature

4. What three properties of a substance affect the amount of energy transferred as heat to or from the
substance? (1 point)
volume, temperature change, specific heat capacity
density, temperature change, specific heat capacity
mass, temperature change, specific heat capacity
mass, temperature change, latent heat

5. Which of the following is true during a phase change? (1 point)
temperature increases
Temperature remains constant.11/29/13 Physics AUnit 4Quiz 1

temperature decreases
There is no transfer of energy as heat
.

7. What condition is necessary for two bodies that are in physical contact with each other to be in thermal
equilibrium? (3 points)

8. A metal bolt with a mass of 8.50 x 10
-2
kg and a temperature of 85.0°C is placed in a container of water.
The mass of the water is 0.150 kg, and its temperature is 25.0°C. What is the specific heat capacity of the bolt if
the final temperature of the bolt and water is 28.4°C? (cp.w = 4186 J/kg•°C) (3 points).

Answer 5

When you apply energy to a system, the particles tend to move faster and faster and they try to escape from the bulk. Eventually, they leave the bulk and become gas and that's why the volume increases.

Answer 6

3. Temperature
4. mass, temperature change, latent heat (which is the amount of heat in the substance)
5. I can't acces the link
7. That they are in equilibrium with the surroundings. Law zero of thermodynamics.

Answer 7

this is #5 sorry about that and thank you bunches!
Which of the following is true during a phase change? (1 point)
