One might compare this to various objects, such as a pillow and a brick. Say you threw a tennis ball against a pillow, it wouldnt bounce very far. However if you threw it at the brick, it would bounce further. By your question i assume you mean to say the effects on how it bounces. So to answer the question, if the ball is flat, it would bounce less, as it is a softer surface, (much like the pillow) and if it is harder, it would bounce more and higher, (much like the ball off of the brick).
Not sure if this helped!
meteorology and water
The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
Mini volleyballs are much smaller than regular volleyballs but beginner volleyballs are the same size as regular volleyballs but are lighter
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
Air doesn't effect the bounce of the ball much higher air pressure the harder the ball lower pressure softer the ball temp effects it too colder soft warmer harder
Wilson volleyballs are the best because the are filled with 10% of helium and 90% of air.
Air is expelled from the alveoli, as well as the lungs in general, during exhalation when the diaphragm relaxes and rises up. This creates pressure on the thoracic cavity, and since there is more air pressure inside than outside, the air is exhaled to relieve the pressure.

Yes
Depends on where you are. Hot weather is for beach volleyball ... beach volleyballs fun too!!!! But if not gym volleyballs the way to go!!!
the temperature of a basketball effects it's bounce because the air partacles in the ball slow down causing it to lose pressure and it doesn't bounce as well. if a ball has more pressure it bounces better.
