Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Temperature is a measure of
the total energy of a substance
the number of particles
the volume
the average kinetic energy of the particles
2.
Evaporation makes the remaining liquid cooler because
the fastest particles escape
the slowest particles escape
particles are added
the volume increases
3.
Which will increase the rate of evaporation?
Lower temperature
Still, humid air
Larger surface area
A covered container
4.
Gases expand more than solids when heated because
gas particles are lighter
gases have more mass
gas particles do not move
forces between gas particles are very weak
5.
A drop of ink spreads through still water. This is
diffusion
evaporation
boiling
condensation
6.
The internal energy of a body is
only its kinetic energy
its temperature
the sum of the random kinetic and potential energies of its particles
its heat capacity
