An ideal gas is taken through a quasi-static process described by $P = \alpha\, V^2$, with $\alpha = 5\,atm/m^6$. The gas is expanded to twice its original volume of $1\,m^3$. How much work is done by the expanding gas in this process
An ideal gas undergoes cyclic process as shown in density pressure graph. During the process $AB$ the work done $|W_{AB}| = 70\,J$ . During the process $BC$, the gas absorbs $150\,J$ of heat. During the process $CA$ , gas undergoes expansion and does $210\,J$ of work
The temperature inside and outside of refrigerator are $260\, K$ and $315\, K$ respectively. Assuming that the refrigerator cycle is reversible, calculate the heat delivered to surroundings for every joule of work done.
Helium gas goes through a cycle $ABCDA$ ( consisting of two isochoric and isobaric lines) as shown in figure Efficiency of this cycle is nearly ....... $\%$ (Assume the gas to be close to ideal gas)
A heat engine is involved with exchange of heat of $1915\, J,$ $-40\, J ,+125\, J$ and $-Q\,J$, during one cycle achieving an efficiency of $50.0 \%$. The value of $Q$ is.......$J$
This question has Statement $1$ and Statement $2.$ Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement $1:$ In an adiabatic process, change in internal energy of a gas is equal to work done on/by the gas in the process.
Statement $2 :$ The temperature of a gas remains constant in an adiabatic process.
During which of the following thermodynamic process represented by $P V$ diagram the heat energy absorbed by system may be equal to area under $P V$ graph?
