Drag each tile to the correct box. water’s specific heat capacity is 4.186 joules/gram degree celsius. mercury’s specific heat capacity is 0.140 joules/gram degree celsius. water and mercury are put into three identical bowls: bowl a contains 20 grams of water. bowl b contains 40 grams of water. bowl c contains 20 grams of mercury. the bowls start at the same temperature, and then the same amount of heat is added to each bowl. order the bowls from coolest to warmest, based on their final temperatures. bowl a bowl b bowl c < < this is chemistry not math oops

The amount of heat depends on three factors:-
#Mass of the material used in bowls.
#Specific heat capacity of the material used in bowls.
#Temperature change.
So, (change in energy) = (mass) x (specific heat capacity) x (temperature change)
Temperature Change = (Change in energy) / (mass x specific heat capacity)
It says "The bowls start at the same temperature, and then the same amount of heat is added to each bowl". It means temperature change varies inversely with product of mass and specific heat capacity.
Higher the product of mass and specific heat capacity, Lower the temperature change, Cooler the bowl will be.
Water’s specific heat capacity is 4.186 joules/gram degree Celsius. Mercury’s specific heat capacity is 0.140 joules/gram degree Celsius.
Water and mercury are put into three identical bowls:
#Bowl A contains 20 grams of water.
#Bowl B contains 40 grams of water.
#Bowl C contains 20 grams of mercury.
So, we have (40g x 4.186 J/g) > (20g x 4.186 J/g) > (20g x 0.140 J/g)
It means temperature change in Bowl B < Bowl A < Bowl C.
Hence, Order of the bowls from coolest to warmest, based on their final temperatures would be Bowl B < Bowl A < Bowl C.
