Match the following items. 1. equilibrium temperature 2. caused by collisions with container walls evaporation = condensation 3. measure of average kinetic energy pressure 4. the intermingling of one substance within another diffusion 5. determined by mass and speed kinetic energy

Hi

Here are the matches that look most appropriate.

Temperature: measure of average kinetic energy

As we know that temperature is a measure of average kinetic energy. The greater the temperature, higher will be collisions between molecules and higher will be their kinetic energies.

Pressure: caused by collisions with container walls

When temperature is increased, it increase the kinetic energies of molecules which causes a greater no. of collision between molecules. If volume of same container is kept constant and only temperature is increased,  it will cause greater collisions of molecules with the wall of containers, which will exert more pressure on the wall.

Diffusion: the intermingling of on substance within another 

Diffusion can be considered as random movement of molecules when they are placed in an environment with the need of no energy from outside. This movement is random and one molecules adheres and intermingles with other without any sequence.

Kinetic energy: determined by mass and speed

Kinetic energy is the energy that moving object display. It is measured by two important factors, mass and speed of any object and can be found as : 1/2 mv ^2.

Evaporation=condensation: equilibrium

A chemical state of equilibrium is reached when the rate of evaporation becomes equal to the rate of condensation of a certain liquid. For example :Acetone.

Hope it help!
