SelectQuestion
If R = universal gas constant, the amount of heat needed to raise the temperature of 2 mole of an ideal monoatomic gas from 273K to 373K when no work is done
Find the change in internal energy of the system when a system absorbs 2 kilocalorie of heat and at the same time does 500 joule of work
A system performs work $\Delta W$ when an amount of heat is$\Delta Q$ added to the system, the corresponding change in the internal energy is $\Delta U$. A unique function of the initial and final states (irrespective of the mode of change) is
A container of volume $1{{m}^{3}}$is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at 300 K. The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be
110 J of heat is added to a gaseous system, whose internal energy change is 40 J, then the amount of external work done is
Which of the following is not thermodynamical function
When the amount of work done is 333 cal and change in internal energy is 167 cal, then the heat supplied is
First law thermodynamics states that
A thermo-dynamical system is changed from state $({{P}_{1}},\,{{V}_{1}})$ to $({{P}_{2}},\,{{V}_{2}})$ by two different process. The quantity which will remain same will be
In thermodynamic process, 200 Joules of heat is given to a gas and 100 Joules of work is also done on it. The change in internal energy of the gas is
