Well, pressure has to be kept constant and so does the mass of the gas with Charles's Law. Charles's Law--V1/T1=V2/T2--can be derived from the Combined Gas Law--V1xP1/T1=V2xP2/T2--by keeping the pressure constant which in turn cancels out the pressure in the Combined Gas Law leaving you with Charles's Law.

Does Charles law the temperature and number of moles stay constant?

Charles' Law: V1/T1 = V2/T2 The number of moles and the pressure are constant.


What factor is kept the same in a scientific experiment?

All variables except for the independent and dependent variables should be kept the same. The other two will be changed by a fixed amount and by an unknown amount to be discovered during the experiment, respectively.

Do the units for the variables in charles' law matter?

For Charles' Law(V1/T1=V2/T2) T1 and T2 must be in Kelvin temperature scale. This way their is no negatives or zero as 0 on the Kelvin scale would be no kinetic energy (absolute zero) which as never occurred as far as we are aware. The Kelvin temperature scale is Celcius minus 273.15 °. The volume however can be whatever you want as long as V1 and V2 are the same in the equation


What gas law states that the volume of gas increases when temperature increases as long as the pressure stays the same?

It would be Charles's Law.
