Question

For a given quantity of gas which has a specific volume under a given pressure and temperature, how would we find its volume under changed conditions of temperature and pressure?

Answer 1

By the combined gas law, `(P_1V_1)/T_1=(P_2V_2)/T_2`

Explanation:

Given `"STP"`, which is `0` `""^@C`, and `100*kPa`, you can easily substitute in to find `V_2`, i.e.

`(P_1V_1xxT_2)/(T_1xxP_2)=V_2`

Have at it..........How could you find the mass of gas, given that `"freon-12"` is `C(Cl)_2F_2`?
