How do you find the water equivalent of a calorimeter?
Calculation: Let water equivalence of a calorimeter = W g Heat lost by warm water= Heat gain by cold water + heat gained by the calorimeter Heat lost by the hot water is = (t2-t3) cal. Heat gained by the calorimeter and the hot water = (W+50) (t3 – t1) cal.
How do you calculate water equivalent?
Equivalent Water = Mass x Specific Heat It is also possible to describe the water equivalent of a given body as the mass of water whose heat capacity equals the heat capacity of a given body.
Why it is necessary to calculate the water equivalent of a calorimeter?
Measurement of W (i.e, water equivalent of the calorimeter) is necessary because during the heat exchange, the calorimeter also takes some amount of heat evolved (due to the reaction) and hence should be taken into account. When both acid and base are strong, the heat released is maximum and is 13.7 kcal.
How will you determine the water equivalent of the flask?
Heat absorbed by the flask may be considered as equivalent to the heat absorbed by a certain mass of water for the same change in temperature, assuming the specific heat of water to be 1 calorie per gram. This calculated mass of water is called the water equivalent of the flask.
What is meant by water equivalent?
Definition of water equivalent : the product of the mass of a body by its specific heat equal numerically to the mass of water that is equivalent in thermal capacity to the body in question.
What is the unit of water equivalent of calorimeter?
The thermal capacity of the body and its water equivalent are numerically equal. If the thermal capacity of the body is expressed in terms of the mass of water then it is called Water equivalence of the body. $\therefore$ The SI unit of water equivalent of the calorimeter is $Kg$.
What is the water equivalent?
: the product of the mass of a body by its specific heat equal numerically to the mass of water that is equivalent in thermal capacity to the body in question.
What is a water equivalent?
What is the dimensional formula of water equivalent?
The SI unit of Water equivalent is Kg and the dimensional formula is [M¹L⁰T⁰].
What is the unit for water equivalent?
The SI unit of Water equivalent is Kg and the dimensional formula is [M¹L⁰T⁰]. Thermal capacity of the body and its water equivalent are numerically equal. If thermal capacity of a body is expressed in terms of mass of water it is called as Water Equivalent of the body.
How much water is a unit?
Each billing unit is 100 cubic feet of water which is equal to 748 gallons.
What is water equivalent Class 11?
Water equivalent is defined as the amount of water that can replaces any substance gaining the same variation in temperature, when provided with the same amount of energy as that of substance.
