Ch 5 L2 Thermal Energy Transfer Quiz

All matter transfers thermal energy by radiation.

• True

• False

Warm objects emit less radiation than cold objects.

• True

• False

Radiation can transfer thermal energy through solids, liquids, and gases.

• True

• False

Conduction is the transfer of thermal energy between materials by the collisions of particles.

• True

• False

Thermal energy always transfers from a cooler object to a hotter object.

• True

• False

In conduction, particles with higher kinetic energy transfer energy to particles with lower kinetic energy.

• True

• False

Metals are better thermal conductors than non-metals.

• True

• False

A thermal insulator is a material through which thermal energy flows easily.

• True

• False

Specific heat is the amount of thermal energy required to increase the temperature of 1 kg of a material by 1°C.

• True

• False

A material with low specific heat needs a lot of energy to change its temperature.

• True

• False
