Question

A sample of water is heated from 30 C to 55 C . (I) What were the initial and final temperatures of water in kelvin scale ? (II) How much was the rise in temperature on Kelvin scale ? (III) How much was the rise in temperature on Celsius scale ?

Answer 1

Answer:

K = 273 + C

1. Let T1 be the initial temperature and T2 be the final temperature of water.

        T1 = 30C = 273 + 30 = 303K

        T2 = 55C = 273 + 55 = 328K

    2. Rise in temperature on Kelvin scale = T2 - T1 = 328 - 303 = 25K

    3. Rise in temperature on Celsius scale = 55 - 30 = 25C
