Explanation:
Given
Temperature of cooling water from engine exit
After Passing through the radiator its temperature decreases to
specific heat of water
Volume of water
density of water
Thus mass of water
Heat transferred to the surrounding is equal to heat absorbed by cooling water
Answer:
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.
What is specific heat capacity?
Specific heat capacity is the quantity
of heat required to raise a unit mass of
a substance by 1 kelvin.
Specific heat capacity of water and sand
{<em>refer to the above attachment}</em>
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.
