Explanation: The correct answer is B) It is a measure of the average kinetic energy of the particles in a system. Temperature is a measure of the average kinetic energy of the particles in a substance or system.

Question 2:

Which of the following best describes heat?

Explanation: The correct answer is D) It is the transfer of energy between objects due to temperature differences. Heat refers to the transfer of energy between objects or systems that occurs due to temperature differences.

Question 3:

Which of the following is an example of conduction?

Explanation: The correct answer is D) Touching a hot metal spoon and feeling it get warm. Conduction is the transfer of heat through direct contact between objects or substances.

Question 4:

Which of the following statements is true about specific heat capacity?

Explanation: The correct answer is A) It is the amount of heat required to raise the temperature of a substance by 1 degree Celsius per unit mass. Specific heat capacity is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount per unit mass.

Question 5:

Which of the following statements is true about thermal equilibrium?

Explanation: The correct answer is A) It occurs when two objects have the same temperature. Thermal equilibrium is reached when two objects have the same temperature and no net heat transfer occurs between them.
