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

Name two major types of errors in measurement and also define them.

Ans 1: The major types of errors in measurement are Systematic Error and Random Error.

Systematic Errors:Systematic errors occurs when repeated measurements of a quantity give the same values under the same conditions.This error is due to poor calibration or zero error in the stop watch. This error can be removed by applying correction factor
Ans 2: Random Error: Random error occurs when repeated measurements of a quantity give different values under the same conditions. This error is due to faulty procedure or negligence and inexperience of person at the time to start or stop the stop watch. This can be reduced by taking average value of observed readings .

Question # 1

Differentiate between the precision and accuracy.

Ans 1: Precision: A measurement which has less absolute uncertainty is called precise measurement. The precision of a measurement is determined by the instrument being used.Absolute uncertainty , in effect, is equal to the least count of measuring instrument.
Accuracy: is the one which has less fractional or percentage error. Accuracy measures,how close a measured value is to the actual value.
