A certain amount of ice is supplied heat at a constant rate for 7 minute. For the first 1 minute, the temperature rises uniformly with time, then it remains constant for the next 4 minute and again rises at a uniform rate for the last 2 minute. Explain physically these observation and calculate the final temperature (in\[{}^\circ C\]). Latent heat of ice \[=336\times {{10}^{3}}J\,\,k{{g}^{-1}}\] and\[{{c}_{water}}=4200J\,\,k{{g}^{-1}}{{K}^{-1}}.\]

Answer:

40.00
