Answer: More heat is required to raise the temperature of 1 g of water 1 ∘C than to raise the temperature of 1 g of ethyl alcohol 1 ∘C.
Benzene is more resistant to temperature change than sulfuric acid.
Water has a high specific heat due to the hydrogen bonding between water molecules.
Sulfuric acid is less resistant to temperature change than water.
Explanation: Specific heat is the the amount of energy that must be absorbed or lost to raise or lower the temperature of 1 g of a substance by 1°C .
Thus from the given values:
Specific heat of water= 4.18
Specific heat of ethyl alcohol= 2.44
Specific heat of benzene= 1.80
Specific heat of sulphuric acid= 1.40
As the specific heat of water is the most, it means most heat is required to raise the temperature of 1 g of water by 1°C and it is because the water molecules are strongly held together by hydrogen bonds.
And more is the value of specific heat, more resistance the substance would be for a temperature change and vice versa.
