The r.m.s velocity of oxygen molecules at 27°C is 318 m/s. the r.m.s velocity of hydrogen molecules at 127°C is
By what percentage should the pressure of a given mass of a gas be increased so as to decrease its volume by 10% at a constant temperature? |
Answer |
The equation of state corresponding to 8 g of O2 is, |
Answer |
Three containers of the same volume contains three different gases. The masses of the molecules are m1, m2 and m3 and number of molecules in their respective container are N1, N2 and N3, the gas pressure in the container are P1, P2, and P3 respectively. All the gasses are now mixed and put in one of these containers. The pressure P of the mixture is |
