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.
