Which of the following is NOT a fundamental property of matter?

  1. Mass

  2. Volume

  3. Temperature

  4. Color


Correct Option: D
Explanation:

Color is not a fundamental property of matter, as it depends on the interaction of light with the material.

The specific heat capacity of a substance is defined as the amount of heat required to raise the temperature of one gram of the substance by one degree Celsius.

  1. True

  2. False


Correct Option: A
Explanation:

The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a given amount.

Which of the following is NOT a mode of heat transfer?

  1. Conduction

  2. Convection

  3. Radiation

  4. Advection


Correct Option: D
Explanation:

Advection is the transfer of heat by the movement of a fluid, while conduction, convection, and radiation are all direct transfer mechanisms.

The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.

  1. True

  2. False


Correct Option: A
Explanation:

The first law of thermodynamics is a fundamental principle of physics that states that energy cannot be created or destroyed.

The second law of thermodynamics states that the entropy of an isolated system always increases over time.

  1. True

  2. False


Correct Option: A
Explanation:

The second law of thermodynamics is a fundamental principle of physics that states that the entropy of an isolated system always increases over time.

Which of the following is NOT a thermodynamic system?

  1. A closed system

  2. An open system

  3. An isolated system

  4. A non-equilibrium system


Correct Option: D
Explanation:

A non-equilibrium system is not a thermodynamic system because it is not in a state of equilibrium.

The efficiency of a heat engine is defined as the ratio of the work output to the heat input.

  1. True

  2. False


Correct Option: A
Explanation:

The efficiency of a heat engine is a measure of how much of the heat input is converted into useful work.

The Carnot cycle is a theoretical heat engine cycle that achieves the maximum possible efficiency for a given set of temperatures.

  1. True

  2. False


Correct Option: A
Explanation:

The Carnot cycle is a theoretical heat engine cycle that achieves the maximum possible efficiency for a given set of temperatures.

Which of the following is NOT a greenhouse gas?

  1. Carbon dioxide

  2. Methane

  3. Water vapor

  4. Nitrogen


Correct Option: D
Explanation:

Nitrogen is not a greenhouse gas because it does not absorb infrared radiation.

The greenhouse effect is a natural process that helps to regulate the Earth's temperature.

  1. True

  2. False


Correct Option: A
Explanation:

The greenhouse effect is a natural process that helps to regulate the Earth's temperature by trapping heat in the atmosphere.

Which of the following is NOT a renewable energy source?

  1. Solar energy

  2. Wind energy

  3. Hydropower

  4. Fossil fuels


Correct Option: D
Explanation:

Fossil fuels are not a renewable energy source because they are formed from the remains of ancient plants and animals.

The Kyoto Protocol is an international agreement that aims to reduce greenhouse gas emissions.

  1. True

  2. False


Correct Option: A
Explanation:

The Kyoto Protocol is an international agreement that aims to reduce greenhouse gas emissions by setting binding targets for industrialized countries.

Which of the following is NOT a type of heat exchanger?

  1. Shell-and-tube heat exchanger

  2. Plate-and-frame heat exchanger

  3. Double-pipe heat exchanger

  4. Regenerator


Correct Option: D
Explanation:

A regenerator is not a type of heat exchanger because it does not transfer heat between two fluids.

The critical point of a substance is the temperature and pressure at which the liquid and gas phases become indistinguishable.

  1. True

  2. False


Correct Option: A
Explanation:

The critical point of a substance is the temperature and pressure at which the liquid and gas phases become indistinguishable.

The triple point of a substance is the temperature and pressure at which the solid, liquid, and gas phases coexist in equilibrium.

  1. True

  2. False


Correct Option: A
Explanation:

The triple point of a substance is the temperature and pressure at which the solid, liquid, and gas phases coexist in equilibrium.
