Which of the following is correct about Specific heat capacity of water?

Correct option is C

The correct answer is (c) The specific heat of water varies slightly with temperature.
Explanation:
· The specific heat capacity of water is not constant over a wide temperature range.
· It shows small variations with change in temperature due to changes in molecular behaviour.
· There is no uniform increase or decrease in specific heat from 0°C onwards.
· Hence, option (c) is the most accurate statement.
Information Booster:
· The specific heat capacity of water is approximately 4.186 J/g°C near room temperature.
· Water has a very high specific heat compared to most substances.
· This property allows water to absorb large quantities of heat with little change in temperature.
· It plays an important role in maintaining thermal stability in natural systems.
Additional Knowledge:
· Option (a) is incorrect because specific heat does not continuously decrease from 0°C.
· Option (b) is incorrect because specific heat does not continuously increase from 0°C.
· Option (d) is incorrect because specific heat does not remain exactly constant between 0°C and 100°C.
· Slight variation in specific heat occurs due to intermolecular forces changing with temperature.
