Thermodynamics ...

In a thermodynamic process a gas expands such that the heat transferred to the gas $$ (d Q)= $$ decrease in internal energy $$ (-d U) . $$ Find

The molar heat capacity

 A cyclic process $$ A B C A $$ is shown in the $$ V-T $$ diagram. Process on the $$ P $$ - $$ V $$ diagram is

A cyclic process $$ A B C D $$ is shown in the following $$ P-V $$ diagram. Which of the following curves represents the same process?

Carbon monoxide is carried around a closed cyclic process $$ a b c, $$ in which $$ b c $$ is an isothermal process, as shown in Fig. 2.115. The gas absorbs 7000 J of heat as its temperature is increased from 300 K to 1000 K in going from $$ a $$ to $$ b $$. The quantity of heat ejected by the gas during the process $$ c a $$ is

An ideal gas (1 mol, monatomic) is in the initial state $$ P $$ (see Fig. 2.111 ) on an isothermal $$ A $$ at temperature $$ T_{0} . $$ It is brought under a constant volume $$ \left(2 V_{0}\right) $$ process to $$ Q $$ which lies on an adiabatic $$ B $$ intersecting the isothermal $$ A $$ at $$ \left(P_{0}, V_{0}, T_{0}\right) . $$ The change in the internal energy of the gas during the process is (in terms of $$ T_{0} $$ ) $$ \left(2^{2 / 3}=\right.1.587)$$

A monatomic gas "undergoes a cycle consisting of two isothermals and two isobarics. The minimum and maximum temperatures of the gas during the cycle are $$ T_{1}=400 $$. K and $$ T_{2}  =800 \mathrm{K}, $$ respectively, and the ratio of maximum to minimum volume is 4

The volume at $$ D $$ is

Two samples $$ A $$ and $$ B $$ of a gas initially at the same pressure and temperature are compressed from volume $$ V $$ to $$\dfrac{ V }{2 }$$ ($$A $$ isothermally and $$ B $$ adiabatically). The final pressure of $$ A $$ is

Three processes compose a thermodynamics cycle shown in the P-V diagram. Process $$ 1 \rightarrow 2 $$ takes place at constant temperature , process $$ 2 \rightarrow 3 $$ takes place at constant volume  and process $$ 3 \rightarrow  1$$ is adiabatic during the complete cycle.The total amount of work done  in the cycle is $$10 J$$. During process $$ 2 \rightarrow 3 $$ the internal energy decreases by $$20 J$$ and during process $$ 3 \rightarrow 1 $$, $$20 J$$ of work done on the system. How much heat is added to the system during process $$ 1 \rightarrow 2 $$?
