Answer:
The question is incomplete, here is the complete question ; Quantity A of an ideal gas is at absolute temperature T, and a second quantity B of the same gas is at absolute temperature 2T. Heat is added to each gas, and both gases are allowed to expand isothermally. If both gases undergo the same entropy change, is more heat added to gas A or gas B?
a. More heat is added to gas A
b. More heat is added to gas B
c.The same amount of heat is added to each gas
Option B is the correct answer = more heat is added to gas B
Explanation:
Considering dQ = dS/T
dQ(A) = dS/T
dQ(B) = dS/2T
From this, it implies that dQ(B) = dQ(A)/2
and as such, more heat is added to gas B or gas B will undergo the greater entropy change
