Sample questions
-
1.An iron ball requires 5000 J heat energy to raise its temperature by 10°C. What is the heat capacity of the iron ball?
- A.50 J K⁻¹
- B.500 J K⁻¹
- C.5000 J K⁻¹
- D.500 J °C⁻¹
-
2.Why are steam pipes more effective than hot water pipes for warming buildings in cold countries?
- A.Steam pipes release more latent heat during condensation than hot water pipes.
- B.Steam pipes transfer heat faster due to higher thermal conductivity.
- C.Hot water pipes lose heat quickly through radiation, reducing efficiency.
- D.Steam pipes operate at higher pressures, increasing heat output.
-
3.What is meant by the term latent heat?
- A.The heat energy required to raise the temperature of a substance by 1°C.
- B.The heat energy absorbed or released during a phase change at constant temperature.
- C.The total heat energy contained in a substance at any given time.
- D.The heat energy lost by a substance when it cools down rapidly.
-
4.Which of the following correctly defines the term heat?
- A.Heat is a form of energy that flows from a body at higher temperature to a body at lower temperature due to the temperature difference between them.
- B.Heat is the total kinetic energy possessed by the molecules of a body.
- C.Heat is the degree of hotness or coldness measured by a thermometer.
- D.Heat is a force that causes temperature to rise in a substance.
-
5.What is the principle of the method of mixtures, what other name is it known by, and which fundamental law underlies this principle?
- A.Heat lost by the hot body equals heat gained by the cold body; principle of calorimetry; law of conservation of energy.
- B.Heat lost by the cold body equals heat gained by the hot body; principle of thermal equilibrium; law of entropy.
- C.Heat transfer depends on mass and temperature difference; principle of thermodynamics; Newton's law of cooling.
- D.Heat energy is conserved only in isolated systems; principle of heat exchange; law of specific heat capacity.
