The first law thermodynamics was gives as `q=Delta U+(-w)`, where q is heat given to a system and `Delta U` represent increase in internal energy and -w is work done by the system. Various process such as isothermal, adiabatic, cyclic, isobaric and isochoric process in terms to first law of thermodynamics leads for important results. The molar heat capacity for 1 mole of monoatomic gas is 3/2R at constant volume and 5/2R at constant pressure.
Which of the following statements are correct:
A. Both work done heat appears at the boundaries of system
B. Heat given to a system is given +ve sign.
C. Heat given to a system is equal to increase in internal energy under isothermal conditions
D. Heat given to a system is used to increase internal energy under isochoric conditions
