Question

The following can change in matter in an increase or decrease in temperature except one?​

Answer 1

Answer:

vapour pressure

Explanation:

ANSWER

Surface tension, viscosity and density will decrease with increase in temperature except for vapour pressure.

Vapour pressure will increase with increase in temperature.

With increase in temperature, kinetic energy of liquid molecules increases. This increases the number of molecules that change phase from liquid to gas. It increases vapour pressure.

Answer 2

Answer:

Therefore, increasing temperature decreases viscosity.With the rise in temperature, which of the following forces can never increase. Solution : With the rise in temperature, only viscosity of gases increases whereas force of surface tension decreases, elastic force decreases. Solid friction does not depend on temperature.
