1.the ocean in September is warmer than the ocean in may.2expensive aluminum pots and pans have copper on the bottom.3the ocean in September is warmer than the ocean in may.4fruit growers spray water on their trees to fight a spring frost.
MY FRIEND alluminium becauce it is cheaply avaible and easy to use
AluminiumNo doubt about that.
1I am guessing here that some assumptions have been madeI guess that we are talking about northern hemisphere and the surface temperature at the beach rather than the global average temperature of the total ocean volumeIf those guesses are justified then the temperature in May will be lower than you might expect because the sun will have only just started filling up the ocean with heatIt takes time to heat water because of its high specific heatIn the autumn, September, the ocean will contain the summer's heat and that will then begin slowly emptying of heatThink of a pot on the stoveYou apply heat and the water is still coldIt remains cold for some timeIf you boil the water then remove the heat the water is still extremely hotYou would still damage your hand if you put your finger inThis will apply for some time even though the heat is not being applied2Specific heat means heat content for a given massIt should be noted that aluminium is much lighter, i.eless dense, than copperFor a given thickness, copper will hold more heat than aluminiumSo pots have two reasons for having copper bottoms: first, they hold more heat for a given thickness so make cooking more even in the pan, and second, copper is a better conductor of heat3See 14Water is a magic substance in many waysIt has a very high specific heatSo it takes a lot of heat to warm it upIf you spray water on to something during the day it will remain at that temperature even if the weather warms or coolsJust like the pot on the stove, it will take time for the temperature to change even when the heat is removedSo when the frost comes, the sprayed leaves will still be at the daytime temperature for some timeHopefully, they will prevent the temperature from dropping to a point where the leaves would have been damaged for long enough for the sun to come out again.
