Question

A sealed flask containing 1.0 mole of H2(g) and a sealed flask containing 2.0 moles of He(g) are at the same temperature. The two gases must have equal

Answer 1

Pressure or Average Kinetic Energy

Step-by-step explanation:

When dealing with sealed containers filled with gas, there are many variables to consider. Namely: pressure, temperature, volume, number of molecules present.

However, this question can be solved easily, without worrying too much about the other variables. Usually the case is that if there is a difference in pressure, there will be a difference in temperature, so the answer could be that both pressures must be equal.

Another way we could look at it is that the Average Kinetic Energies between the two containers have to be equal, and this will then lead to the temperatures being equal without worrying about other variables.
