Chapter 4.1 Thermal Equilibrium

You leave your cold spoon in a hot bowl of oatmeal. What happens after an hour?

• The temperature of both the oatmeal and the spoon stay the same

• The spoon and the oatmeal become the same temperature

• Only the temperature of the oatmeal will change

• Only the temperature of the spoon will change

Temperature is a measure of the...

• total energy in a substance

• total kinetic energy in a substance

• average potential energy in a substance

• degree of hotness of an object

Diagram shows two bodies A and B which are in thermal equilibrium. Which of the following statement is False?

• The net rate of heat flow is zero

• The heat flow in both directions is the same

• The final temperature of both bodies is the same

• The final physical characteristics of both bodies are the same

Which of the following points are used in the calibration of thermometer?

• Melting point of ice and freezing point of ice

• Melting point of ice and boiling point of water

• Boiling point of water and condensation point of water

• Melting point of ice and condensation point of water.

Which of the following is NOT an advantage of mercury as a thermometric liquid?

• It does not stick on glass

• Its boiling point is high

• It required more heat energy to heat it up.

• It is a good conductor which expands uniformly.
