A calorimeter of mass m contains an equal mass of water in it. The temperature of water and calorimeter is t2. A block of ice of mass m and temperature t3 < 0oC is gently dropped into the calorimeter. Let C1, C2 and C3 be the specific heats of calorimeter, water and ice respectively and L be the latent heat of fusion of ice.  
Q. 
The whole mixture in the calorimeter becomes ice if  
  • a)
    C1t2 +  C2t2 + L + C3t3 ≥ 0 
  • b)
    C1t2 + C2t2 + L + C3t3 ≤ 0 
  • c)
    C1t2 +  C2t2 – L + C3t3 ≥ 0
  • d)
    C1t2 + C2t2 – L – C3t3 ≤ 0  
Correct answer is option 'B'. Can you explain this answer?
