What has a property of losing and gaining heat quickly?
A
water
B
soil
C
sand
D
cactus
Explanation: 

Detailed explanation-1: -Explain that sand and sandy soils absorb heat more quickly but also lose it more quickly. Conversely, darker soils absorb but also release heat more slowly.

Detailed explanation-2: -Dry sand soil has the unit specific heat capacity is about 800 J/kg K and saturated sand soil is about 1632 J/kg K (See Table 1).

Detailed explanation-3: -Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster.

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.
