Air vs Water Heat Capacity

Simple science experiment, which shows that water is able to absorb much more heat comparing to air.

i had to whach this is my h.w. :(

Totally agree. ..and that guy is from NASA?!

This is a bit misguiding video about heat capacity (cp). The reason why balloon burst is not due to "low" heat capacity of air but due to low heat transfer rate from the balloon surface to the inside air. The ratio of cp_water/cp_air is about 3, but that of heat transfer coefficients of liquid and gas is around 100. If one would put a hydrogen gas (which has 3x higher cp than water) instead of air the balloon would still burned out.

Noone is disputing we need to make resource decissions, but tricking people to think we have control on the climate - by changing light bulbs and riding to work - is dilussion/dangerous. The environmental movement is guilty (at least) of the pushing of biofuels and that is killing hungry now - one of the greatest human made disarsters.

If you think you have it right with your understanding of GW, would you put YOUR life on it, now - not future generations yours! I think you wouldn't.

Guys, the only thing you have done in this clip is falsified your hypothesis of CO2 related GW. You are demonstrating that water is the main 'greenhouse gas' and has no close competition. CO2 actually has a lower heat capacity than air. You are tricking the public to believe that CO2 is quickly increasing the atmos temp; reality is that low heat cap gases heat faster than high- as demonstrated in other related clips. The proof is around us, we don't use CO2 to trap heat, but we do water.
