Answer:
Inside it's usually warm so when you open a door to outside which is cold a cold front and a warm front will be exposed to each other cold will win usually since cold goes below the warm front.
Explanation:
The answer will be A since chemical where discovered
I think it’s A. Troposphere❤️

So, the question would would probably ask if the gold ring is indeed pure gold. Let's calculate the specific heat capacity of the calorimeter. If this is equal to the given specific heat for pure gold, then the the gold ring is pure gold.
Qwater = mCdT = (50 g)(4.18 J/gC)(31 - 23.7) = 1525.7 J
Through conservation of energy,
Qwater = Qcalorimeter = mCdT = 1525.7
1525.7 = (10.5)(C)(78.3 - 31)
Solving for C,
C = 3.072 J/gC
Since the specific heat of the calorimeter is not equal to that of the pure gold (0.1291 J/gC), then the gold ring is not pure.
