Two gases A and B are separated by a partition within a box. Gas B expands and move the partition, doing 200j of work on gas A. 400j of energy are transferred to gas A from B due to a temperature difference. What is the net total change of the internal energy from gas A?
The net total change in the internal energy of gas A can be determined by summing up the work done on gas A and the energy transferred to gas A due to the temperature difference.
Given:
Work done on gas A: 200 J (positive because work is done on gas A)
Energy transferred to gas A due to temperature difference: 400 J (positive because energy is transferred to gas A)
Net total change in internal energy of gas A = Work done + Energy transferred
= 200 J + 400 J
= 600 J
Therefore, the net total change in the internal energy of gas A is 600 J.
To determine the net total change in internal energy for gas A, we need to consider both the work done on gas A by gas B and the energy transferred to gas A due to a temperature difference.
Given:
Work done on gas A by gas B (W) = 200 J
Energy transferred to gas A from B due to a temperature difference (Q) = 400 J
To calculate the net total change in internal energy (ΔU) of gas A, we can use the First Law of Thermodynamics, which states that the change in internal energy (ΔU) is equal to the sum of the heat transfer (Q) and the work done (W):
ΔU = Q + W
Substituting the given values:
ΔU = 400 J + 200 J
Calculating the sum:
ΔU = 600 J
Therefore, the net total change in internal energy for gas A is 600 Joules.
