Question

5. A vessel contains n moles of H2. Pressure of the gas is made
double by adding additional n moles of H2 at same
temperature. Internal energy of the system:
(a) becomes twice (b) becomes 2 times
(c) remains same (d) becomes four times​

Answer 1

Answer:

internal energy also doubles because pressure is directly proportional to internal energy

Answer 2

The correct option is b.

• We know that the internal energy of a system is directly proportional to the pressure of the system.
• Internal energy is denoted by the symbol "U".
• The pressure of a system is denoted by the symbol " P".
• If we double the pressure of gas its internal energy will also become two times of initial.
