Which of the following statement is true? Worik appears at the boundary of the system. (ii) Change in the state is completely defined when the initial and fianl states are specified. (iii) Temperature is a state funciton. (iv) Work is a state function.
Statement: Both work and heat are manifested by an effect in the surroundings. Explanation: Work done by // on the system and DeltaH appear only at the boundary of system.
The first law of thermodynamics was given as q=DeltaU+(-w) , where q is heat given to a system and DeltaU represents increase in internal energy and -w is work done by the system. Various processes such as isothermal, adiabatic, cyclic, isobaric and isochoric process in terms of I law of thermodynamics leads for important results. The molar heat capacity for 1 mole of monoatomic gas is 3/2 R at constant volume and 5/2 R at constant pressure. Which of the following statements are correct? (1) Both work and heat appears at the boundaries of system. (2) Heat given to a system is given +ve sign. (3) Heat given to a system is equal to increase in internal energy under isothermal conditions (4) Heat given to a system is used to increase internal energy under isochoric conditions (5) Both work and heat are not state functions but their sum (q+w) is state function.
Assertion : Work is a state function. Reason : Work does not depend upon the path.
Assertion: Both Delta H and DeltaU are state functions. Reason : A state function depends only on the initial and final states of the system and is independent of the path.
if work is done by the system then W is
The non- expansion work of a system
State the conditions under which a force does no work.?
Heat given to a system is 30 joules and work done by the system is 15 joules. The change in the internal energy of the system will be
