Which are assumed to be constant while using the combined gas
law?
pressure
number of moles
volume and moles of gas
pressure and temperature
Homework Answers
Solution :-
While using the combined gas law the formula used is P1V1/T1 = P2V2/T2
therefore in this formula the moles of the gas are assumed to be constant.
So the answer for the combined gas law constant is moles of gas.

Combined Gas Relationship Since the Ideal Gas Law produces a constant (R), it can be used to look at a gas sample in which initial and final conditions have changed. The combined gas relationship is as follows P.V R=P.V2 n, T n2 T2 where P, Vi,and T, and n, are the initial pressure, volume, temperature, and number of moles of gas. The final conditions are represented by P, V2, T2 and n2. If any of the conditions in the initial...

For a fixed amount of gas at constant pressure, the "volume of the gas is proportional to its Kelvin temperature. When the pressure and temperature are held constant, B. the volume of a gas is proportional to the number of moles present. For a fixed amount of gas at constant temperature, the pressure and volume of the...

c) (6 pts) Calculate the molar mass of methane. 10. (10 pts) Terrence finds that all gases exhibit virtually the same behavior in response to temperature and pressure changes, no matter what the gaseous compound's formula mass or shape. The physical properties of gases depend on only four variables: pressure (P), volume (V), Kelvin temperature (T), and number of moles (n). All four variables can be changed simultaneously, but experimenting with only two at a time while keeping the other...
