Question

One mole of gas absorbs 200j of heat at constant volume its temp rise from 298k to 308k the change in internal energy is

Answer 1

using the formula

Cv=dq/dT

(cv=change in internal energy at constant volume, dq=heat ,dT=change in temperature)

Cv=200/308-208

200/100=2j

hence chnge in energy =2joule
