According to kinetic theory, the particles in a ................... are considered to be small, hard spheres with an insignificant volume

• solid

• liquid

• gas

NGSS.MS-PS1-4

The motion of the particles in a gas is rapid, constant, and random.

• True

• False

NGSS.HS-PS3-2

Kinetic theory says that all collisions between particles in a gas are perfectly elastic.

• True

• False

During an elastic collision, kinetic energy is transferred without loss from one particle to another, and the total kinetic energy of the system remains constant.

• True

• False
