Checkpoint: States of Matter - Elizabeth Peterson | Library

1

Which of the following changes made to a sample of liquid would result in an increase in the distance between the individual molecules of the substance?

Transferring the substance to a smaller container

 Adding heat to the substance

 Changing the phase of matter from liquid to solid

 Decreasing the overall kinetic energy of the liquid

1

 The illustration should show increased movement of the atoms

 Each individual atom should be larger

 There should be VERY WIDE spaces between the atoms

 The shape of each atom must reflect the shape of the container

1

 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

1

A=particles become more tightly packed

 B=the pressure of the substance decreases

 C= kinetic energy of particles increases

 D= particles become more widely spaced

Spreading Out, Slowing Down

Moving closer, Slowing Down

Moving Closer, Speeding Up

 Spreading out, Speeding Up

1

Tightly Packed, Moving Around Easily

 Moving, Close Together

Spread Out, Moving Around Rapidly

Tightly Packed, Rigid

1

The motion of atoms or molecules within a substance

The transfer of thermal energy from one object to another

 The average temperature of a system over time

The average kinetic energy of the system as a whole
