Question

300J heat is released from the system,
when 500J work is done on that system.
What is the change in internal energy?

Answer 1

Required Answer:-

Given that,

• 300J heat is released from the system, when 500J work is done on that system.

To calculate :

• The change in internal energy.

Formula :

$\red{ \star} \underline{ \boxed{ \sf{U = q + w}}}$

Here,

• U denotes internal energy⠀⠀⠀⠀⠀
• q denotes electric charge
• w denotes the work done

Inserting the values in the equation,

$\longrightarrow \rm Internal \: energy = 500J - 300J$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\longrightarrow\underline {\boxed{\rm{ \purple{Internal \: energy = 200J}}}} \blue{ \bigstar}$

Therefore, the change in internal energy is 200J.
