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

• A

  $50{ }^{\mathrm{o}}\mathrm{C}$
• Correct answer
  B

  $>50{ }^{\mathrm{o}}\mathrm{C}$
• C

  $<50{ }^{\mathrm{o}}\mathrm{C}$ but $>0{ }^{\mathrm{o}}\mathrm{C}$
• D

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

Hence, the correct answer is option: 'B'.
