In a gas expansion, 69 J of heat is absorbed from the surroundings, and the energy of the system decreased by 118 J. Calculate the work done.
_______ J
thank you
To calculate the work done in a gas expansion, we can use the formula:
Work = Change in Energy - Heat absorbed.
Given that the energy of the system decreased by 118 J and 69 J of heat is absorbed from the surroundings, we can substitute these values into the formula:
Work = -118 J - 69 J
Simplifying the equation, we have:
Work = -187 J
Therefore, the work done in the gas expansion is -187 J.
