During a process,a system absorbs $710 \ J$ of heat and increases its internal energy by $460 \ J$. What is the work performed by the system (in $J$)?

“The mass and energy both are conserved in an isolated system”,is the statement of

If $65 \ kJ$ of work is done on the system and it releases $25 \ kJ$ of heat,what is the change in internal energy of the system (in $kJ$)?

In an adiabatic process,no transfer of heat takes place between the system and surroundings. Choose the correct option for the free expansion of an ideal gas under adiabatic conditions from the following:

The mathematical equation of the first law of thermodynamics for an isochoric process is:

$A$ system is provided with $50 \ J$ of heat and the work done on the system is $10 \ J$. What is the change in internal energy of the system in joules?
