Answer:
Explanation:
Given:
- Initial temperature of water,
- final temperature of water,
- energy spent in one hour of walk,
- volumetric capacity of stomach,
<em>Now, let </em><em>m </em><em>be the mass of water at zero degree Celsius to be drank to spend 450 kilo-calories of energy.</em>
We know:
.....................................(1)
where:
m = mass of water
Q = heat energy
temperature difference
= specific heat capacity of water
<u>Putting values in the eq. (1):</u>
Since water has a density of 1 kilogram per liter, therefore the volume of water will be:
