States of Matter

a glass container is in what state of matter?

• solid

• liquid

• gas

• plasma

when molecules are close together and vibrating slowly in place, what state of matter are they in?

• solid

• liquid

• gas

• plasma

when molecules are slightly spread out and sliding around at a medium speed, what state of matter are they in?

• solid

• liquid

• gas

• plasma

when molecules are freely spread out and quickly moving around, what state of matter are they in?

• solid

• liquid

• gas

• plasma

When thermal energy is increased

• molecules do not changed

• molecules move slower and come together

• molecules move faster and spread out

• molecules stop moving

thermal energy is added during which phase changes? (check all that apply)

• boiling

• freezing

• melting

• condensing

thermal energy is removed during which phase changes? (check all that apply)

• boiling

• freezing

• melting

• condensing

during the phase change of condensing, thermal energy is removed causing

• the Kinetic Energy of molecules to stay the same

• the Kinetic Energy of molecules to decrease

• the Kinetic Energy of molecules to increase

• the Kinetic Energy of molecules to equal zero

during a phase change,

• the molecular structure changes

• the speed and the attraction between molecules changes

• the type of atom changes

• the number of atoms changes

steam coming from a pot of boiling water is in what state of matter?

• solid

• liquid

• gas

• plasma
