Which law of thermodynamics states that the total energy of an isolated system remains constant?

  1. First Law of Thermodynamics

  2. Second Law of Thermodynamics

  3. Third Law of Thermodynamics

  4. Zeroth Law of Thermodynamics


Correct Option: A
Explanation:

The First Law of Thermodynamics states that the total energy of an isolated system remains constant, meaning that energy can neither be created nor destroyed, only transferred or transformed.

What is the term for the spontaneous tendency of heat to flow from a hotter object to a colder object?

  1. Entropy

  2. Enthalpy

  3. Heat Capacity

  4. Thermal Conductivity


Correct Option:
Explanation:

Heat Transfer refers to the spontaneous tendency of heat to flow from a hotter object to a colder object, driven by the difference in temperature between the two objects.

Which law of thermodynamics states that the entropy of an isolated system always increases over time?

  1. First Law of Thermodynamics

  2. Second Law of Thermodynamics

  3. Third Law of Thermodynamics

  4. Zeroth Law of Thermodynamics


Correct Option: B
Explanation:

The Second Law of Thermodynamics states that the entropy of an isolated system always increases over time, meaning that the system tends to become more disordered and less organized.

What is the term for the amount of heat required to raise the temperature of a substance by one degree Celsius?

  1. Specific Heat Capacity

  2. Latent Heat

  3. Heat of Fusion

  4. Heat of Vaporization


Correct Option: A
Explanation:

Specific Heat Capacity refers to the amount of heat required to raise the temperature of a substance by one degree Celsius.

Which law of thermodynamics states that the entropy of a perfect crystal at absolute zero is zero?

  1. First Law of Thermodynamics

  2. Second Law of Thermodynamics

  3. Third Law of Thermodynamics

  4. Zeroth Law of Thermodynamics


Correct Option: C
Explanation:

The Third Law of Thermodynamics states that the entropy of a perfect crystal at absolute zero is zero, meaning that the system is in a state of perfect order and has no thermal motion.

What is the term for the amount of heat required to change a substance from a solid to a liquid?

  1. Specific Heat Capacity

  2. Latent Heat

  3. Heat of Fusion

  4. Heat of Vaporization


Correct Option: C
Explanation:

Heat of Fusion refers to the amount of heat required to change a substance from a solid to a liquid.

Which law of thermodynamics states that two systems in thermal equilibrium with a third system are in thermal equilibrium with each other?

  1. First Law of Thermodynamics

  2. Second Law of Thermodynamics

  3. Third Law of Thermodynamics

  4. Zeroth Law of Thermodynamics


Correct Option: D
Explanation:

The Zeroth Law of Thermodynamics states that two systems in thermal equilibrium with a third system are in thermal equilibrium with each other, providing a basis for temperature measurement.

What is the term for the amount of heat required to change a substance from a liquid to a gas?

  1. Specific Heat Capacity

  2. Latent Heat

  3. Heat of Fusion

  4. Heat of Vaporization


Correct Option: D
Explanation:

Heat of Vaporization refers to the amount of heat required to change a substance from a liquid to a gas.

Which of the following is not a type of heat transfer?

  1. Conduction

  2. Convection

  3. Radiation

  4. Specific Heat Capacity


Correct Option: D
Explanation:

Specific Heat Capacity is a property of a substance, not a type of heat transfer.

What is the term for the transfer of heat through direct contact between two substances?

  1. Conduction

  2. Convection

  3. Radiation

  4. Specific Heat Capacity


Correct Option: A
Explanation:

Conduction refers to the transfer of heat through direct contact between two substances.

Which of the following is not a thermodynamic system?

  1. A closed system

  2. An open system

  3. An isolated system

  4. A homogeneous system


Correct Option: D
Explanation:

A homogeneous system is not a thermodynamic system, as it does not have a definite boundary.

What is the term for the transfer of heat through the movement of a fluid?

  1. Conduction

  2. Convection

  3. Radiation

  4. Specific Heat Capacity


Correct Option: B
Explanation:

Convection refers to the transfer of heat through the movement of a fluid.

Which of the following is not a thermodynamic property?

  1. Temperature

  2. Pressure

  3. Volume

  4. Specific Heat Capacity


Correct Option: D
Explanation:

Specific Heat Capacity is a property of a substance, not a thermodynamic property.

What is the term for the transfer of heat through electromagnetic waves?

  1. Conduction

  2. Convection

  3. Radiation

  4. Specific Heat Capacity


Correct Option: C
Explanation:

Radiation refers to the transfer of heat through electromagnetic waves.

Which of the following is not a unit of work?

  1. Joule

  2. Newton-meter

  3. Watt-second

  4. Calorie


Correct Option: D
Explanation:

Calorie is a unit of heat, not work.
