The air pressure decreases, because all the force is being pushed down, not up. Such as a pile of people. :D The person on the bottom is probably hurting so mch, because of all the weight and PRESSURE. The person on the top is probably laughing his or her head off because she has no pressure.
Warm, moist air will rise, then cool; this forms clouds.
It will increase.
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
The density is reduced to 50% (half) of its original value.
The density will be 50 % from the initial value.
the warm air rises up and moves over the cold air that is already there.
it rises up
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
it gets warmer as it rises
It expands and cools
Ofcourse, the volume will increase Ofcourse, the volume will increase
cold air replaces it
it gets warmer
Electricity and volume This happens because when the mass expands over heat the density expands which in turn makes the volume expand
The temperature of air is decreased.
The temperature of air is decreased.
it gets warmer
