When the same amount of heat is added to cold sand and cold water, the temperature change of sand will be higher because of its lower specific heat capacity.
<h3>What is specific heat capacity?</h3>
Specific heat capacity is the quantity of heat required to raise a unit mass of a substance by 1 kelvin.
<h3>Specific heat capacity of water and sand</h3>
Water, c = 4,200 J/kg⁰C
Sand, c = 830 J/kg⁰C
Q = mcΔθ
where;
- Δθ is temperature change
- Q is quantity of heat added
Δθ = Q/mc
Thus, for an equal mass of water and sand, when the same amount of heat is added to cold sand and cold water, the temperature change of sand will be higher because of its lower specific heat capacity.
