(how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

What determines the average kinetic energy of the particles in a gas? a. the number of collisions b. the number of particles c. the size of the particles d. the temperature

Which of these is a physical property
