Answer:
use formula Ep=mgh
Explanation:
potential energy is being utilized
The gas releases an amount of heat equal to -225 J
Explanation:
The change in internal energy of a diatomic gas is given by:
where
n is the number of moles
R is the gas constant
is the change in temperature
For this gas we have:
n = 0.235 mol
So, the change in internal energy of the gas is
Now we can use the 1st law of thermodynamics to find the heat absorbed/released by the gas:
where
Q is the heat absorbed by the gas
W is the work done by the gas
Here we have:
Solving for Q, we find:
Where the negative sign means the heat has been released by the gas.
