What is the unit of heat capacity?

• Joules per Kelvin (J/K)

• Joules per gram per degree Celsius (J/g°C)

• Kelvin per Joule (K/J)

• Celsius per gram (°C/g)

Which property describes the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius?

• Specific heat

• Heat capacity

• Thermal conductivity

• Latent heat

Why is water often used as a coolant in machinery?

• Because it has a high specific heat

• Because it is a good conductor of electricity

• Because it is inexpensive

• Because it evaporates quickly

What does the equation Q = mcΔT represent?

• The relationship between heat transfer and temperature change

• The formula for calculating pressure

• The equation for determining velocity

• The principle of conservation of mass

How does the specific heat of metals like copper and aluminum compare to that of water?

• Metals have a lower specific heat than water

• Metals have a higher specific heat than water

• Metals and water have the same specific heat

• Specific heat cannot be compared between metals and water
