Question

An ideal gas undergoes an isochoric process. during which 322 J of heat are absorbed from the environment. How much work was done on or by the gas? 322 J done on gas 322 J done by gas 161 J done on gas 161 J done by gas By how much did the thermal energy of the gas increase or decrease? increased by 322 J decreased by 322 J increased by 16l J decreased by 161 J thermal energy didn't change An ideal an adiabatic process, during which 322 J of work are done by the gas. How much heat entered or left the gas? 322 J entered gas 322 J left gas 161 J entered gas 161 J left gas no heat flowed into or out of the gas By how much did the thermal energy of the gas increase or decrease? increased by 322 J decreased by 322 J increased by 161 J decreased by 161 J. thermal energy didn't change An ideal gas undergoes an isothermal process, during which 322 J of work are done on the gas. How much heat entered or left the gas? 322 J entered gas 322 J left gas 161 entered gas 161 J left gas no heat flowed into or out of the gas By how much did the thermal energy of the gas increase or decrease? increased by 322 J decreased by 322 J increased by 161 J decreased by 161J thermal energy didn't change

Explanation / Answer

14) in a isochoric process volume is coanstant so w = p(chaneg in volume) = 0

15) from 1st law of thermodynamics q = u+w

q = u = 322 J

16) in a adiabatic process heat is constant so heat is loss or gain by the system

17) q = u+w

u = -w = -322 J

18) in a isothermal process temperature is constant so change in internal energy is zero

q = w = 322 J

19) thermal energy is constant
