Question # 1

Define derived units.

Ans 1: The units associated with the derived quantities are called derived units. SI units for measuring all other physical quantities are derived from the base and supplementary units. For Example, newton, joule, watt, pascal etc.

Question # 1

Discuss the conventions for using SI units?

Ans 1: The various conventions for using SI are given below.
1. Full name of the unit does not begin with a capital letter even if named after a scientist.
2. symbol of unit name after scientist has initial capital latter for for example N for newton Pa for pascal H3 for hertz etc
3. The prefixes is written before an adjacent to the unit
4. The combination of units is written each with one space a part For example , Torque =55 N m
5. Double, triple etc prefixes are not allowed
6. When a multiple of base unit is raised to a power. The power applies to the whole multiple and not just the base unit
7. Before substituting values in the formula to calculate the final result make sure that all the included physical quantities are expressed in their SI units.

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.
