An ideal gas expands from volume This may be achieved by either of the three processes:isobaric, isothermal and adiabatic. Let U be the change in internal energy of the gas, Q be the quantity of heat added to the system and W be the work done by the system on the gas. Identify which of the following statements is false for U?

 

  • (A):U is least under adiabatic process.
  • (B):U is greatest under adiabatic process.
  • (C):U is greatest under the isobaric process.
  • (D):U in isothermal process lies in-between the values obtained under isobaric and adiabatic processes.

Best Answer

Correct Answer:

(B): U is greatest under adiabatic process.
