Specific heat capacity?

Question

state and explain one advantage and one disadvantage of using water rather than air as a cooling material?

Answer 1

Water cooling has many advantages over air cooling.

Water has a thermal conductivity of 0.6062 W/ (m*K) whereas the thermal conductivity of air is only 0.0262.

This means heat can be drawn away more efficiently with water.

Water also has a much higher specific heat capacity than air (1.0 J/ (kg*K) versus 0.24), which allows the water cooling system to absorb a lot more energy before heating up.

Answer 2

Advantage: Water has a higher specific heat capacity  i.e takes in more energy to increase its temp as compared to air. It takes in alot of energy before heating up as compared to air, thus making it more efficient in doing its job as a cooling material.

Disadvantage: Its nature tends to be more messy as compared to air i.e. using water to cool certain electronics might end up in the electronic spoiling upon contact.
