A box of gas is place in a room of higher temperature. The room transfers 1080j of energy to the gas. 400 of work are done to gas. What is net total change of the internal energy the gas in the box?
The net total change of the internal energy of the gas in the box can be found by subtracting the work done on the gas from the energy transferred to the gas.
Net total change of internal energy = Energy transferred to the gas - Work done on the gas
Net total change of internal energy = 1080 J - 400 J
Net total change of internal energy = 680 J
To calculate the net total change of the internal energy of the gas, we need to consider the energy transferred to the gas and the work done on the gas. The internal energy change is given by the equation:
ΔU = Q - W
where ΔU is the change in internal energy, Q is the energy transferred to the gas, and W is the work done on the gas.
In this case, we have Q = 1080 J (energy transferred to the gas) and W = 400 J (work done on the gas).
Plugging in the values, we get:
ΔU = 1080 J - 400 J
ΔU = 680 J
Therefore, the net total change of the internal energy of the gas in the box is 680 Joules.
