Answer: Option (C) is the correct answer.
Explanation:
Specific heat is defined as the amount of heat necessary to raise the temperature of substance by one degree Celsius.
Mathematically, \(Q = mc \Delta t\)
where Q = heat
m = mass of substance
c = specific heat
\(\Delta t\) = change in temperature
Since mass is same for all the given substances. Therefore, more is the specific heat of a substance more frequently it will raise the temperature.
- Specific heat of copper is 0.385.
- Specific heat of iron is 0.444.
- Specific heat of liquid water is 4.184.
- Specific heat of sand is 0.290.
Thus, we can see that specific heat of liquid water is highest out of the given options.
Hence, we can conclude that liquid water absorb most heat before its temperature changes significantly.
