Heat is supplied to a certain amount of ice at a constant rate for 9 min. For' the first 1 min, the temperature rises uniformly with time, Then the temperature remains constant for the next 5 min and after that again temperature rises at uniform rate for last `3 min`. If the ratio of magnitude of final temperature to initial temperature is `P^(circ) C`, then find the 'value of `4 P`. (Given: `S_ (ice )=0.5 (cal) (g)^(-1)/overset(o) \ C^(-1), L_(f)=80 (cal g).

A certain amount of ice is supplied heat at a constant rate for 7 min. For the first one minute the temperature rises uniformly with time. Then it remains constant for the next 4 min and again the temperature rises at uniform rate for the last 2 min. Given S_("ice")=0.5cal//g^(@)C,L_(f)=80cal//g . The initial temperature of ice is

A certain amount of ice is supplied heat at a constant rate for 7 minutes. For the first one minute the temperature rises uniformly with time. Then, it remains constant for the next 4 minute and again the temperature rises at uniform rate for the last two minutes. Calculate the final temperature at the end of seven minutes.
