A a glass bowl B a frying pan C water D aluminum foil
I have heard that the new tanks are well insulated the way they areWon't hurt to put more around it but I don't think you will notice your water will be any hotter upstairsMay have less heat lost from the tank but it's not going to get the water any hotterThe temperature of the water is set with a thermostatI have a new one and I think it's set very lowThe colder you have it set the less it will cost to runYou can turn the screw on the thermostat up and make it hotter but that will cost more money to run.
Metals have a low specific heat valueValues given for each item are: A a glass bowl s 0.84 J/(g·K) Depends slightly on the formulation of the glassB a frying pan s 0.450 J/(g·K) Assuming an iron frying panC water s 4.183 J/(g·K) D aluminum foil s 0.897 J/(g·K) The greatest value of specific heat capacity is that of waterHope this is helpfulJIL HIR
