Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at ${100^{\rm{o}}}C$, while the other one is at ${{\rm{0}}^{\rm{o}}}C$, If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is

less than ${50^{\rm{o}}}C$ but greater than ${0^{\rm{o}}}C$

Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at

{100^\mathrm{o}}C

, while the other one is at

{\mathrm{0}^\mathrm{o}}C

, If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is

View answer and explanation

Correct option: C

more than

{50^\mathrm{o}}C

Option C (more than

{50^\mathrm{o}}C

) is correct because the body at

{100^\mathrm{o}}C

has a greater heat capacity, leading to a final temperature closer to

{100^\mathrm{o}}C
