The heat released by the gas is -225 J
Explanation:
First of all, we have to calculate the change in internal energy of the gas, which for a diatomic gas is given by
where
n = 0.235 mol is the number of moles
is the gas constant
is the change in temperature
Substituting,
Now we can us the 1st law of thermodynamics to find the heat absorbed/released by the gas:
where
is the change in internal energy
Q is the heat
W = 205 J is the heat done by the gas
Solving for Q,
Since the sign is negative, it means the heat has been released by the gas.

<u>In modern physics</u>, as it was called "Stefan-Boltzmann law", the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the black body's temperature T
as:
where: P is the power (total energy radiated per second per square meter) and T is the temperature of a black body.
then we can make a ratio between the state of before quadruple (with subscript 1) and after (with subscript 2) as:
As
Then
then
- The factor will the total energy radiated per second per square meter increase = 256
