What gas law is used to calculate the pressure of gas at various volume assuming temperature stays constant?

If you know other factors, you could use PV=nRT, where P is pressure, V is volume, n is the number of moles of the gas, R is the gas constant (typically 0.0821, but it depends on the units of the other factors), and T is temperature.
However, if you don't know those other factors, or have no need for them, Boyle's law will suffice: P1V1=P2V2.

What happens to the pressure as the volume changes?
Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
If a gas is contained in a 5.0 L containter at a pressure of 100kPa what size container would be required to contain the gas at a pressure of 50 kPa assuming constant temperature?
10.0
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
When a container decreases in size what will happen to an amount of gas in the container?
Assuming the temperature stays constant and there is no leakage of gas, then if the container decreases in size then the pressure will increase.
If the temperature of gas in the container decreases what happens to its pressure?
Assuming the volume is kept constant, the pressure will also decrease in this case.
What happens to the pressure as the volume changes?
Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
Do gases expand in heat?
Yes. If the temperature increases, the gas expands (assuming the pressure remains constant).
Assuming no change in temperature and pressure calculate the volume of O2 in liters required for the complete combustion of 14.9 L of butane C4H10?
Assuming no change in temperature and pressure, calculate the volume of O2 (in liters) required for the complete combustion of 14.9 L of butane (C4H10):
How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
What is the kind of matter that can change in shape but not volume?
Liquids. By assuming that temperature and pressure are constant so that volume does not change.
How are Charles law and boyles law alike?
Boyles Law deals with conditions of constant temperature. Charles' Law deals with conditions of constant pressure. From the ideal gas law of PV = nRT, when temperature is constant (Boyles Law), this can be rearranged to P1V1 = P2V2 (assuming constant number of moles of gas). When pressure is constant, it can be rearranged to V1/T1 = V2/T2 (assuming constant number of moles of gas).

How to calculate final pressure when given initial pressure and initial temp and also final temp and know that it's a constant volume process from initial state?
You can calculate pressure and temperature for a constant volume process using the combined gas law.
What will happen to pressure when gas expands and volume increases?
As the pressure increases, the volume wil decrease.
What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature?
assuming the balloon is closed, the air pressure would double
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
