Question

Q3.A sample of water was heated from 35°C to 40°C.(a) What were the initial and final temperatures of water in Kelvin scale(b) How much was the rise in temperature on Celsius scale?c) How each was the rise in temperature on Kelvin scale?​

Answer 1

HERE   IS  YOUR  ANSWER , I HOPE  IT  HELPED  IF  IT  DID, THEN PLEASE  MARK  IT AS  THE  BRAINLIEST

A )     initial temperature of water = 35 degree celsius

final temperature of water = 40 degree celsius

B )     rise in temperature = final temp. - initial temp.

                                          = 40 - 35

                                          => 5 degree celsius

C )    initial temperature of water  on kelvin scale = 35 + 273 k

                                                                                     = 308k

    final temperature of water  on kelvin scale = 40 + 273k

                                                                                 = 313 k

rise in temperature = final temp. - initial temp.

                                 = 313k - 308k

                                 = 5 k
