Question

A system absorbs 600 J o f heat and work equivalent to 300 J on its surroundings. The change in internal energy is: (A) 300 J (B) 400 J (C) 500 J (D) 600 J

We know that Δ E=Q + W= 600 + (-300) = 300 J W= - 300, because the work is done by the system

Q. A system absorbs $600 J$ o f heat and work equivalent to $300 J$ on its surroundings. The change in internal energy is:

$300 J$

$400 J$

$500 J$

$600 J$

We know that $Δ E = Q + W = 600 + (- 300) = 300 J$
$W = - 300,$ because the work is done by the system

Q. A system absorbs 600J o f heat and work equivalent to 300J on its surroundings. The change in internal energy is:

300J

400J

500J
