When the temperature of a gas decreases at constant volume, its a. pressure increases. b. mass increases. c. pressure decreases. d. particles move faster.

a. pressure increases

b. particles move faster

Explanation:

When the temperature of a gas at constant volume increases, it means the kinetic energy of the gas particles will also increase and this means that the particles will move at a faster speed.

Also, since the particles are moving faster, it means they will be hitting the walls of the container carrying the gas at a faster rate.

And the higher the force, the higher the Pressure.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
