Which of these is heated up the least by the sun's energy? Concrete Sand Sea Soil

Option C

Explanation:

The higher the specific heat capacity of a substance, the higher will be the time taken to heat them.

Here,

Specific heat capacity of Concrete is 880 J/kg°C

Specific heat capacity of water is 4181 J/kg°C

Specific heat capacity of sand is 840 J/kg°C

Specific heat capacity of soil is 1810 J/kg°C

Hence, out of all these water will be heated the least by sun's energy

Hence, option C is correct
