What happens when there is a temperature difference between two objects?
energy is transferred from the hotter object to the cooler object
the objects maintain their initial temperatures
energy is transferred from the cooler object to the hotter object
no energy transfer occurs
|
At what point does energy transfer between two objects stop?
when the objects reach thermal equilibrium
energy transfer never stops
when the hotter object reaches room temperature
when the cooler object reaches room temperature
|
Which of the following is NOT a method of energy transfer by heating?
conduction
insulation
radiation
convection
|
What happens to particles when an object is heated?
they start vibrating less as they lose kinetic energy
they remain stationary
they start vibrating more as they gain kinetic energy
they change their size
|
How do vibrating particles pass energy to neighbouring particles in conduction?
by direct contact
by emitting radiation
by creating a vacuum
by changing their mass
|
What happens to a hot object during conduction?
it cools down
it changes its shape
it heats up
its temperature remains constant
|
During radiation, what happens to the hot object?
it radiates more energy than it absorbs
it radiates and absorbs equal amounts of energy
it absorbs more energy than it radiates
it does not radiate or absorb energy
|
What is the purpose of wrapping an object in an insulator?
to slow down energy transfer
to increase the temperature of the object
to change the direction of energy transfer
to speed up energy transfer
|
What is the term for materials that easily transfer energy?
|
Describe the process of energy transfer by conduction.
