WHAT IS EXACTLY FOMENTATION??? AND HOW DOES SPECIFIC HEAT CAPACITY DEPEND ON MASS?
Asked by rajkoth20002 | 19th Jul, 2017, 08:00: PM
Fomentation is the application of hot packs to reduce the pain in body parts. By fomentation, patients suffering from pain get relief by maintaining the swollen body parts of patients at a moderate temperature, around 50 °C. Hot water is used for fomentation as it can store a large amount of heat energy at low temperature due to its high specific heat.
Specific heat capacity:
Heat capacity of a body when expressed for unit mass is called its specific heat capacity. It is denoted by the symbol c. Thus the specific heat capacity of a substance (or a body) is defined as the heat capacity per unit mass of that body, that is
The specific heat capacity of a substance is the amount of heat energy required to raise the temperature of unit mass of that substance through 1°C (or 1 K).
Thus, it does not depend on the mass of the body but is the characteristic property of the substance of the body.

- a calorimetry of mass 50g contains 200g of water at 30degree celcius . Calculate the final temperature of the mixture when 40g of ice at -10degree celcius is added to it.
- find result of mixing 10g of ice at-10c of water at 10c
- Is heat a conserved quantity? Give reason in suport of your answer?
- The temperature of 170g of water at 50degree celsius is lowered to 5degree celcius by adding certain amount of ice to it.Find the mass of ice added . (Take ,specific heat capacity of water=4200J/kg0c and specific latent heat of ice =36000J/kg)
- Water falls from a height of 50m. Calculate the rise in the temperature of water when it strikes the bottom. G=10ms-2 C=4200J/Kg°C
