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
Water has a high specific heat, which means it needs a lot of energy to increase its temperature.
True
False
Thermal contraction occurs when an object's temperature increases.
True
False
When particles lose thermal energy, they slow down and get closer together, decreasing volume.
True
False
Thermal expansion causes a decrease in a material's volume.
True
False
A hot air balloon rises because the air inside expands, making it denser.
True
False
Ovenproof glass is designed to expand more than ordinary glass.
True
False
Convection occurs only in solids.
True
False
Convection currents cause fluids to move in a cycle, transferring heat.
True
False
Which method of thermal energy transfer involves electromagnetic waves?
Conduction
Convection
Radiation
Evaporation
Which of the following is an example of radiation?
