Question

Specific heat of Argon at constant Pressure is o.125 cal | g | K and at constant volume is 0.075 cal | g | K. Calculate the density of argon at N.T.P. Given that J = 4.2J | cal? 

Answer 1

Specific heat at constant and Pressure, C_P = 0.125 cal | g | K 

C_P = 0.125 × 4.2 × 1000 J | Kg | K

C_P = 525 J | Kg | K →1) 

Specific heat at constant volume, C_V = 0.075 cal | g | K
