Mrac [35]

Answer:

So Q=\int Tds

From cycle we can say that

q_{in}=T_2\left ( s_2-s_1 \right )

JulijaS [17]
The reason has to do with the amount of work necessary to remove heat from a substance, which increases substantially the colder you try to go. To reach zero kelvins, you would require an infinite amount of work.
