Is it possible to convert internal energy into works?

Define the term 'enthalpy'. What will happen to the internal energy if work is done by the system ?

A : During a cyclic process work done by the system is zero. R : Heat supplied to a system in the cyclic process converts into internal energy of the system.

Which of the following statement is correct? (A) only internal energy is a state function but not work (B) only work is a state function but not internal energy (C) Both internal energy and work are state functions (D) Neither internal energy nor work is state function

In an isothermal expansion change in internal energy and work done by the gas are respectively

Solar energy is converted into ATP in or Light energy is converted into chemial energy in the presence of

An ideal monoatomic gas undergoes a process in which its internal energy U and density rho vary as Urho = constant. The ratio of change in internal energy and the work done by the gas is

What will happen to internal energy if work is done by the system?

In what process is the heat added entirely converted into internal energy of the system ?
