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

What is Scientific Notation .Explain ?

Ans 1: Writting number in power of ten or standard from N=M*10ⁿis called scientific Notation.
Explanation:With the help of Scientific Notation, we can express very large number or small number very easily. A large or small number "N" can be expressed in term of a number "M" and a power of '10 '
N= M * 10ⁿ-------------------(1)
In equation 1 "M" represents a number whose first digit is non-zero digit. "n" represents the power of 10, which may be positive or negative
For example 150,000,000,000 m can be expressed in scientific notation as under
150,000,000,000 m = 1.5* 10¹¹m
