Detailed explanation-1: -Sand also has a relatively low specific heat. Water, on the other hand, has a very high specific heat. It takes a lot more energy to increase the temperature of water than sand. This explains why the sand on a beach gets hot while the water stays cool.

Detailed explanation-2: -Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their temperatures change more quickly.

Detailed explanation-3: -Those in the water are most likely feeling cooler than those on the sand. This is due to the high specific heat capacity of water. In other words, the same amount of heat energy when applied to sand and water will increase the temperature of the sand more than it will increase the temperature of the water.

Detailed explanation-4: -Since, specific heat capacity of water is more than that of sand, it takes more time to become hot. For sand, the specific heat capacity is very less, so it heats up quickly during the day.

Detailed explanation-5: -At the end of a sunny summer day at the beach you will notice that while the sand is very hot, sea water is still cool. This happens since sand has a Specific Heat Capacity (S.H.C) of 830J/kgoC, meaning that with 830J of heat energy gained from the sun, the temperature of 1kg of sand increases by 1oC.
