Question

A 10L closed cylinder contains 2g hydrogen nd 2g deuterium gas at 27 degree celsius . Find the internal pressure of the cylinder... Please solve it friends...​

Answer 1

Answer:

this is a question dealing with constant volume or Isochoric increase in temperature. You can assume the gas is a compressible gas with compressibility being independent of temperature. Under this assumption:

P_1 * V = n*Z*R *T_1 and

P_2 * V = n*Z*R* T_2

dividing the two equations and rearranging

T_2 = T_1 (P_2/P_1)

substituting values:

T_2= 273.15* 2.5/2

T_2= 341 Kelvin or 68 degree centigrade.

If compressibility is also a function of temperature, then we have different values of compressibility for the two cases and the best way is to substitute the function instead of Temperature.
