Question

A liquid cools down from 70 degree Celsius to 60 degree Celsius in 5 minutes. the time taken to cool it from 60 degree Celsius to 50 degree Celsius will be​

Answer 1

Given:

A liquid cools down from 70 degree Celsius to 60 degree Celsius in 5 minutes.

To find:

The time taken to cool it from 60 degree Celsius to 50 degree Celsius will be​

Solution:

From given, we have,

A liquid cools down from 70 degree Celsius to 60 degree Celsius in 5 minutes.

⇒ 70 °C - 60 °C = 10 °C

10 °C per 5 minutes.

Similarly, the time taken to cool it from 60 degree Celsius to 50 degree Celsius will be,

⇒ 60 °C - 50 °C = 10 °C

10 °C per 5 minutes.

But, can be lesser or greater than 5 minutes depending upon the density of the liquid.
