But here are the problems: How will you make sure all the heat released goes into the water?
Maybe the reaction releases heat, well watch the system warm up over time.
This process releases heat and makes the steam feel hot.
In theory such a system would be able to "hide" data without releasing heat.
Regular breaks allow more time for the body to release heat built up during exercise.
The heat released from a person's back, combined with some insulation, can keep the water liquid.
These reactions release heat, which is why fire is hot and makes light.
Of the heat released from the ground at Yellowstone, about 25% is by conduction.
If a reaction releases heat, that means it is exothermic.
Your body can then release heat and moisture faster.
