An ideal gas expand against a constant external pressure at 2.0 atmosphere from 20 litre to 40 litre and absorb `10kJ` of energy from surrounding . What is the change in internal energy of the system ?

A system absorbs 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?

A system absorbs 50 kJ heat and does 20 kJ of work. What is the net change in the internal energy of the system ?

A gas expands against a constant pressure of 1 atm from a volume of 5L to 10L. During the process, system absorbs 400 J of heat from the surroundings. Calculate the change in the internal energy of the system.

A gas contained in a cyclinder fitted with a frictionless piston expands against a constant external pressure of 1 atm from a volume of 5 litres to a volume of 10 litres. In doing so it absorbs 400 J of thermal energy from its surrounding .Determine the change in internal energy of system.

Frictionless and weightless piston was fitted into a cylinder containing a gas This gas was allowed to expand from one litre to 5 litre against a constant pressure of one atmosphere in doing so, 200 J of heat was absorbed from the surrounding . The change in the internal energy of the system is :

A gas contained in a cylinder fitted with a frictionless piston expands against a constant external pressure or 1 atm from a volume of 5 litres to a volume of 10 litres. In doing so it absorbs 400 J of thermal energy from its surroundings. Determine the change in internal energy of system.
