Unequal heating of the atmosphere
Answer:
CaCl2=1
KCl=3
Explanation:
CaCl2 has a very high heat of solution hence it is best at melting ice. It is better than all the other salts mentioned. Its dissolution in water produces a lot of heat which melts the ice.
maybe 1+8 (4+548) 4/6 4+4
Heat always flows from hot to cold. The aluminum is hotter than the water in the cup so the answer is 2: The heat is transferred from the aluminum to the water, and the temperature of the water increases.
