transferring the substance to a smaller container
Adding heat energy to the substance
Changing the phase of matter from liquid to solid
Decreasing the overall kinetic energy of the liquid

the basic unit of an element
solid
liquid
gas
atom
state
atom
changes in either ____ or ____ can cause changes in the state of matter
temperature, pressure
As thermal energy is added to a substance, which of the following changes can be predicted?
As kinetic energy decreases, temperature is not affected
As kinetic energy increases, temperature decreases
As kinetic energy decreases, temperature increases
As kinetic energy increases, temperature increases
as kinetic energy increases temperature increases
particles moving freely at a very fast speed
solid
liquid
gas
atom
state
gas
describe the relationship between kinetic energy and states of matter
When particles have low kinetic energy, they do not have enough motion to overcome the attraction for the other particles; they are a solid. As the kinetic energy increases, the more movement there is and the particles have enough motion to become a liquid. As the kinetic energy continues to increase, the particles have enough motion to become
particles move around and slide past each other in a given area
solid
liquid
gas
atom
state
liquid
Describe the movement of atoms in a liquid during a temperature change (both an increase and a decrease in temperature).
When a substance is heated, the particles gain kinetic energy and they move, vibrate, and slide past each other more. As the temperature is lowered, they lose kinetic energy and their motion slows down.
