Question # 1

Enthalpy is a state function Justify?

Ans 1: The total heat content of a system is called enthalpy. Equation
H= E+PV E,P and V are state functions so enthalpy is also a state function.It is not possible to measure the enthalpy of a system in a given state.However change in enthalpy can be measured for achange in the state of system.

Question # 1

Explain " Rounding off numbers ?

Ans 1: The quantities in a measurement are always rounded off to certain level of accuracy. The following rules must be observed while rounding off a number.
1. If the dropping digits is less than "5" then the last retained digit is kept as it is For example 863.73 is rounded to 863.7
2. If the dropping digits is greater than '5' then the last retained digits is increased by '1' for example 9.66 is rounded to 9.7
3. If the dropping digits is '5' and the last retained digit is even then it will be remain uneffected. For example 66.45 is rounded to 66.4
4. If the dropping is '5' and the last retained digit is add, then it will be increases by '1' for example 76.35 is rounded to 76.4
