PLEASE HURRY A sample of gas does 150J of work against its surroundings and loses 90J of internal energy in the process. Does the gas gain or lose heat, and how much?

the heat gained by the system (gas) is 60 J.

Explanation:

Given;

work done by the gas sample, W = 150 J

change in internal energy, ΔU = -90 J

Apply the first law of thermodynamic;

ΔU = Q - W

where;

Q is the heat gained by the system

From the equation above;

Q = ΔU + W

Q = -90 + 150

Q = 60 J

Therefore, the heat gained by the system (gas) is 60 J.

where's the following? you gotta add it to know what the choices are

explanation:

scientific laws are the result of testing theories and proving them to be facts.
