900j of work are done on a volume gas. The gas is placed next to a higher temperature reservoir, which gives 1250j of energy to the gas. What was the total change on the internal energy of the gas due to the reservoir and work done?
The total change in internal energy of the gas is the sum of the work done on the gas and the energy transferred to the gas from the reservoir.
Change in internal energy = Work done on the gas + Energy transferred to the gas
Change in internal energy = 900j + 1250j
Change in internal energy = 2150j
To find the total change in internal energy of the gas, we need to consider the work done on the gas and the energy given to it by the reservoir.
The total change in internal energy (ΔU) can be calculated by using the equation:
ΔU = Q + W
Where:
ΔU is the change in internal energy
Q is the energy added to the system (reservoir)
W is the work done on the system (work done on the gas)
Given:
Q = 1250 J (energy added by the reservoir)
W = 900 J (work done on the gas)
Substituting the given values into the equation, we get:
ΔU = 1250 J + 900 J
ΔU = 2150 J
Therefore, the total change in internal energy of the gas due to the reservoir and work done is 2150 J.
