Question

A sample of water was heated from 30°C to 45°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?​

Answer 1

I hope that this answer will help you

Answer 2

The initial temperature on the kelvin scale = 303k.

The initial temperature on the kelvin scale = 303k.The final temperature on the Kelvin scale = 318k.

Given,

Water heated from 30c to 45c.

To Find,

Initial and final temperatures of water in the Kelvin scale.

The increase in temperature on the Kelvin scale.

Solution,

We can subsequently solve the problem.

we know that

K = C + 273

here,

k = kelvin scale temperature

c = temperature in centigrade

273 = standard temperature

Therefore, 30 centigrade converted into kelvin scale

K = 30 + 273

= 303k

45 centigrade convert into kelvin scale

K = 45 + 273 = 318k

Hence, The initial temperature on the kelvin scale = 303k.

Hence, The initial temperature on the kelvin scale = 303k. The final temperature on the Kelvin scale = 318k.
