Heating a gas increases its' volume if the pressure remains constant. Heating a gas with the volume consant increases the pressure. See the Related Question linked to the the left of this answer: = How do you solve an Ideal Gas Law problem? =

What things can effect air to rise?
Heat can cause air to rise :)
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
What effect does the obsence of heat have on air molecules?
When heat touches air molecules they speed up but when cold air touches molecules they slow down.
What is the process by which gases hold heat in the air?
The greenhouse effect
How does cold air effect the density of gas?
'Cold' air will have less volume so the density is greater.
How does heat effect urine?
Urine doesn't create or excrete heat. It dissipates heat and it would be the value of the temperature and the volume of the urine probably expressed in "calories" of heat energy. For humans the urine exits the body at about 99 degrees, but the volume would be a variable.
What are the functions of air expansion apparatus?
a device that demonstrate how heat affects the volume of a gas.
How does density volume and mass makes the hot air balloon to work?
Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise ad the volume becomes more. Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise and the volume becomes more.
Weather is caused by variations in what three basic ingredients?
temperature, pressure, volume, and density temperature, pressure, volume, and density
Is an urban heat island effect cool or warm?
The urban heat island effect is a warming effect. Unban means 'city'. Buildings and roads retain more heat and warm the air around them, so cities are warmer then the countryside.
The volume of air in a balloon decreases as soon as it is taken out of the warm store and into the cold air This is due to?
System volume of a gas is directly related to pressure, volume, amount of molecules, and the gas constant. When the balloon is moved to cooler air it loses heat. The loss in temperature results in a contraction of volume.
Why you consider evaporation is heat-absorbing process has a cooling effect?
the hot air is being lifted or released into the air
