Question

When 300 J of heat given to an ideal gas with C_p= 72R its temperature raises from 20^ C to 50^ C keeping its volume constant. If n is the number of moles of the gas, then what is the value of 100n ? ( R=8.314 J/ mol .K )

Accepted Answer

Correct answer: 48. (48) Given: C_P= 72R, so C_V=C_P-R= 52R Q=nC_V T (constant volume) 300=n 52 8.314 30 n=0.48 mol 100n=48

$When 300 J of heat given to an ideal gas with C_{p} = \frac{7}{2} R its temperature raises from 20^{\circ} C to 50^{\circ} C keeping its volume constant. If n is the number of moles of the gas, then what is the value of 100 n ? (R = 8.314 J / mol . K)$
