Specific Heat Capacity Quiz

What is specific heat capacity?

• The amount of heat required to change the color of a substance

• The amount of heat required to change the state of a substance from solid to liquid

• Amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius

• The amount of heat required to lower the temperature of a substance by one degree Celsius

What is the formula to calculate specific heat capacity?

• P = VI

• F = ma

• E = mc^2

• Q = mcΔT

What are the units of specific heat capacity?

• Kg/J

• m/s²

• J/kg°C

• J/°C

What is the specific heat capacity of water?

• 6.32 J/g°C

• 3.14 J/g°C

• 2.5 J/g°C

• 4.18 J/g°C

How does specific heat capacity affect the temperature change of a substance?

• It causes the substance to change color

• It increases the pressure of the substance

• It affects the temperature change by determining how much heat energy is required to change the temperature of a substance.

• It has no effect on the temperature change

When a substance releases heat and undergoes a phase change, what term is used to describe the heat involved?

• Specific heat capacity

• Latent heat

• Thermal expansion

• Conduction

How is specific heat capacity different from heat capacity?

• Specific heat capacity is only applicable to solids, while heat capacity is applicable to all states of matter.

• Specific heat capacity is measured in joules, while heat capacity is measured in calories.

• Specific heat capacity measures the temperature change, while heat capacity measures the energy change.

• Specific heat capacity measures heat required for a unit mass, while heat capacity measures heat required for the entire substance.

What are the factors that affect the specific heat capacity of a substance?

• Age, height, and width

• Volume, pressure, and conductivity

• Color, shape, and density

• Type of material, mass, and temperature

Calculate the specific heat capacity of a substance if 500 J of heat is required to raise the temperature of 2 kg of the substance by 10°C.

• 25 J/kg°C

• 100 J/kg°C

• 50 J/kg°C

• 10 J/kg°C

Which statement is true about substances with a higher specific heat capacity?

• They heat up or cool down quickly.

• They conduct heat poorly.

• They require more heat to change their temperature.

• They have a lower boiling point.
