A gas expands against a variable pressure given by `P = (20)/(V)` (where P in atm and V in L). During expansion from volume of 1 litre to 10 litre, the gas undergoes a change in internal energy of 400 J. How much heat is absorbed by the gas during expansion?
A gas expands from 10 litre to 20 litre at a constant pressure of 2 atmospheres. What is the work done by the gas during the expansion ?
A gas expands from 40 litres to 90 litres at a constant pressure of 8 atmosphers. Work done by the gas during the expansion is
An ideal gas expands from 500 cm^3 to 700 cm^3 against 1 atm pressure, by absorbing 2J of energy. Calculate change in internal energy of the ideal gas.
One mole of an ideal diatomic gas undergoes a transition from A and B along a path AB as shown in the figure The change in internal energy of the gas during the transition is
Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum until its total volume is 20 litres. How much heat is absorbed and how much work is done in the expansion?
