Question
A cyclic process of an ideal monoatomic gas is shown in figure. The correct statement is (are) :
Options
A.Work done by gas in process AB is more than that of the process BC.
B.net heat energy has been supplied to the system.
C.temperature of the gas is maximum in state B.
D.in process CA, heat energy is rejected out by system.
Solution
in cyclic process.
ᐃU = 0 ᐃQ = ᐃW as ᐃW = + ve
∴ ᐃQ = +ve
or Net heat energy has been supplied to the system. in process CA
ᐃW = 0 ᐃU = −ve (As T = decreases
∴ heat energy is rejected out by system
ᐃU = 0 ᐃQ = ᐃW as ᐃW = + ve
∴ ᐃQ = +ve
or Net heat energy has been supplied to the system. in process CA
ᐃW = 0 ᐃU = −ve (As T = decreases
∴ heat energy is rejected out by system
