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.

<u>0.4 mol of </u> molecules has larger mass than 0.4 mol of O atoms
<h3>What are molecules?</h3>
The smallest component of a substance that possesses both its chemical and physical characteristics. One or more atoms make up molecules.
They may have the same atoms (for example, an oxygen molecule has two oxygen atoms) or different atoms if they have more than one (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules like DNA and proteins can include thousands of atoms.
the lowest recognised unit into which a pure material can be divided while retaining its chemical makeup and attributes is made up of two or more atoms.
