Heat and Temperature Quiz

What is conduction of heat?

• Transfer of heat through direct contact between particles of a substance

• Transfer of heat through sound waves

• Transfer of heat through electromagnetic waves

• Transfer of heat through fluid movement

Explain an example of conduction of heat.

• When a plastic spoon is placed in a hot cup of tea, the heat from the tea is conducted through the spoon and warms up the handle.

• When a metal spoon is placed in a hot cup of tea, the heat from the tea is conducted through the spoon and warms up the handle.

• When a book is placed in a hot cup of tea, the heat from the tea is conducted through the book and warms up the pages.

• When a feather is placed in a hot cup of tea, the heat from the tea is conducted through the feather and warms up the air around it.

What is convection of heat?

• Transfer of heat through solid objects

• Transfer of heat through electromagnetic waves

• Transfer of heat through the movement of fluids

• Transfer of heat through sound waves

Describe an example of convection of heat.

• When hot air rises and cold air sinks

• When heat is transferred through electromagnetic waves

• When hot air sinks and cold air rises

• When heat is transferred through direct contact

What is radiation and how does it transfer heat?

• Radiation is the transfer of heat through electromagnetic waves.

• Radiation is the transfer of heat through conduction

• Radiation is the transfer of heat through physical contact

• Radiation is the transfer of heat through convection

Provide an example of heat transfer through radiation.

• Heat from a fire

• Heat from a microwave

• Heat from a hot pan

• Heat from the sun

What is specific heat capacity?

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

• The amount of heat required to raise the temperature of a unit volume of a substance by one degree Celsius

• The amount of heat required to raise the temperature of a substance by ten degrees Celsius

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

How is specific heat capacity different from heat capacity?

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

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

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

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

What is thermal expansion?

• Change in shape, area, and volume in response to a change in temperature

• Change in electrical conductivity with temperature

• Change in state from solid to liquid

• Change in color due to temperature

Give an example of thermal expansion in everyday life.

• Metal bridge expanding in hot weather

• Plastic melting in the sun

• Glass breaking when heated

• Wood shrinking in cold weather
