A number of small drops of mercury adiabatically coalesce to form a single drop. The temperature of the drop will
Text Solution
Verified by ExpertsThe correct answer is:
A
Heat neither enters nor leaves n system in an adiabatic process.
From first law of thermodynamics 
where Q is the energy,
W is work done and
is internal energy.
In an adiabatic process 
.
When drop is compressed, work is done Hence, 
Hence, internal energy increases, because of which temperature increases.
