Two cups m and n contains the same mass of water, m is at 25°c while n is at the temperature of 102°c. If both cups are placed in the same freezer of internal temperature - 45°c. Which of the content of m and n freezes first ? Hence, show that tₘ⁻ tₙ = - wc In(²¹/₁₀). where tₘ and tₙ are the time taken for m and n to freezes and w is the mass of water and c is specific heat capacity of water.
