Question

which cools and heats faster

Answer 1

Land cools and heats faster than water

Answer 2

Which cools and heats faster among land and water?

Land

1. We need to get that, land and water really get a similar measure of heat.        It's exactly how much heat is expected to raise the temperature/hotness of the thing.

2. The phenomena responsible is Heat Capacity is a proportion of the measure of heat important to raise the temperature of one mole of a pure substance by one degree Kelvin, however instinctively it implies how much heat energy you need to "settle up" so as to build the temperature(or hotness) of a specific substance.

3. Water is incredible at "putting away heat", since it takes a great deal of heat energy to really heat it when contrasted with state metal and sand.  

4. The inverse applies a similar way as well. Water chills off more slow than land regardless of whether they discharge energy at a similar rate.
