of heat must be added up to the second reservoir to make both reservoirs have the same increase in entropy.
Entropy is the measure of systems thermal energy per unit temperature.
Mathematically,
Entropy = 
ΔS = 
For reservoir first ,
Q (heat) = 400 J
Temperature = 
° C = ° + 273 K
= 243K
Therefore ,
ΔS = 
J/K
For second reservoir,
Q = ?
Temperature = 0° C + 273°
= 273 K
ΔS = 
According to question, Entropy of both the systems are same
Therefore,
= J/K
Q = 
J
Q = 449.38 J

Answer:
Where is the pic or sum ? How can i tell ?
Explanation:
though alchemists were often superstitious, they left a rich legacy of modern chemists. what was their main contribution-
Explanation:
they were the first to preform experiments.
Answer:
Ok; just use PV=nRT solve for n.
Explanation:
The water from the lake must first evaporate from the liquid state to the gaseous state and then condense in the air to form vapors.
The water molecules absorb energy while evaporating and release it when condensing. Their motion gets faster when they are evaporating and slows back down upon condensation.
