$\green{\mathcal{∆U =\:80}}$

→ In equation form, the first law of thermodynamics is ΔU = Q − W.

→ Here,

• ΔU is the change in internal energy U of the system.

• Q is the net heat transferred into the system.

• W is the net work done by the system

So, ∆U = 230 - 150 = 80

$\blue{\mathcal{So, \; ∆U = \:80 }}$
