Which substance has the lowest specific heat? a) beach sand b) beach water c) ice d) pool water

Beach sand.

Explanation:

The specific heat capacity of sand is lower than the water that's why

the beach sand gets hot on hots day.

Specific heat capacity:

"The amount of heat require to raise the temperature of one gram of substance by one degree"

it mean that water require more heat to raise the temperature while sand get hot by absorbing small amount of temperature.

The specific heat capacity of water is 4200 J Kg-1 °C-1

The specific heat capacity of sand is 840 J Kg-1 °C-1

Equation:

C = Q/ ΔT

Here C is the heat capacity, ΔT is the change of temperature of substance by absorbing heat and Q is the energy in joule.

Another equation:

Q = C× m × ΔT

m is the mass of given substance. The specific heat capacity of water very high than other substances that make a water compound in term of temperature.
