Question

a sample of water was heated from 30degree celsius to 45 degree celcious

(a) what were the initial and final temperature of water in Kelvin scale

(b) how much rise in temperature of water in Kelvin scale

(c) how much was the rise in temperature on Celsius scale​

Answer 1

Answer:

a) 308.13 K and 318.13 K

b) 10 K

c) 10 °C

Explanation:

Initial Temp(in celsius)= 30 degree Celsius

Final Temp(in celsius) = 45 degree Celsius

(a)

now the relation between kelvin scale and celsius scale is

K= 273.13 + C

now

Put C=35 in above formula

273.13 + 35 = 308.13 K

for C=45

273.13 + 45= 318. 13 K

(b) Rise in temp in kelivin scale = 318.13 - 308.13

= 10 K

(C) Rise in temp in celsius scale= 45-35= 10° C
