According to the First Law of Thermodynamics, which of the following statements is true?

• Heat is a form of energy that can be created and destroyed.

• Heat can be transferred from a cold object to a hot object without external energy.

• Heat is a form of energy that can neither be created nor destroyed, only transferred.

• Heat is not a form of energy and does not follow the law of conservation.

What does the Zeroeth Law of Thermodynamics state?

• If two bodies are in thermal equilibrium with a third body, they are not in equilibrium with each other.

• If two bodies are in thermal equilibrium with a third body, they are also in equilibrium with each other.

• If two bodies are in thermal equilibrium, they must be at the same temperature.

• If two bodies are not in thermal equilibrium, they cannot exchange heat.

What is the Second Law of Thermodynamics primarily concerned with?

• The unrestricted creation and destruction of heat energy.

• The transfer of heat energy from a body at a lower temperature to a body at a higher temperature without the addition of outside energy.

• The prediction of energy costs for heating and cooling systems.

• The concept of entropy and the direction of heat transfer.

What is "absolute zero" according to the Third Law of Thermodynamics?

• The temperature at which matter contains a maximum amount of energy.

• The temperature at which matter is at its most disordered state.

What does entropy describe in a thermodynamic system?

• The transition of energy from one form to another.

• The amount of disorder in the system.

• The process of heat transfer by direct contact.
