The volume of a fixed mass of gas is 300...

The volume of a fixed mass of gas is `300 cm^3` at STP. When the temperature is related to `50^@C` at constant volume, the pressure exerted by the gas becomes 900mmHg. What is the pressure coefficient of the gas?

Text Solution

Verified by Experts

Here `p_t=900mmHg,p_0=760 mmHg` and `t=50^@C`
`becausep_1=p_0(1+gamma_vt)`
`thereforeY_v=(p_t-p_0)/(p_0t)`
or,`gamma_v=(900-760)/(760 times50)=140/(760 times50)=0.00368^@C^-1`.
