Given:

A gas perform work of expansion =1000 J by absorbing the heat 1600 J.

To find:

Internal Energy change for the thermodynamics process ?

Calculation:

In these type of questions, its best to use the equation for 1st Law of Thermodynamics:

 \boxed{ \sf  \therefore \: \Delta Q = \Delta U + W}

  • Here , heat has been absorbed, so sigh of ∆Q will be positive.

  • Also, work has been done by system (i.e. expansion) , so sign of W will be positive.

 \implies \sf   \:  (+ 1600)= \Delta U + ( + 1000)

 \implies \sf   \: 1600= \Delta U + 1000

 \implies \sf    \Delta U  = 1600 - 1000

 \implies \sf    \Delta U  =600 \: joule

So , internal energy (U) increases and is equal to 600 Joule.

Answer:

600

Explanation:

∆U=q+w

expansion : w= - negative

compression : w = + positive

U = q - w

= 1600 - 1000

= 600
