Physics Formulas

Temperature

  • It is the thermal condition of a body that determines its ability to transfer heat to other bodies
  • Relation between Celsius and Fahrenheit scales is F= 9/5C + 32
  • General relation for any arbitrary scale of temperature.

arbitrary scale

Where ‘s’ is reading on a scale.

Linear expansion

linear expansion

α-Coefficient of linear expansion.

t2 – l1 : : Increase in length

t2 – t1 : : Increase in Temperature

Superficial or areal expansion

areal expansion

β- Coefficient of areal expansion

a2 : a1 : Increase in area

t2 – t1 : Increase in temperature.

Volume Expansion

volume expansion

γ- Coefficient of volume expansion

V2 – V1 : Increase in volume

t2 – t1 : Increase in temperature

Relation between α, β and γ

α: β: γ = 1:2:3

α, β and γ are measured /°C.

Variation of density of solids

d0 = dt (1 + γt )

d0 and dt are densities at 0°C and t°C respectively.

Expansion of Liquid

  • Liquids have definite volume, but do not have definite shape. So they have only cubical expansion.
  • When liquid is heated in a container the container also expands. Hence liquids have two types of cubical expansion.
  • On heating liquids expand. The expansion is more than that for solids.
  • There are two coefficients of expansion for a liquid.
  1. Coefficient of apparent expansion.
  2. Coefficient of real expansion.

Coefficient of apparent expansion (γa)

The coefficient of apparent expansion of a liquid is the ratio of the apparent increase in the volume of the liquids per degree rise of temperature to its. Original volume.

apparent expansion

Where v2 – v1 = apparent increase in volume

(t2 – t1) = Increase in temperature.

v1 = volume at t1°C

v2 = volume at t2°C

Coefficient of real expansion (γr)

The coefficient of real expansion of a liquid is the ratio of the real increase in volume of the liquid to its original volume per 1°C rise of temperature.

real expansion

v2 – v1 = real increase in volume

t2 – t1 = increase in temperature.

v1 = volume at t1°C

v2 = volume at t2°C

Properties of matter are listed below:

Ideal gas or perfect gas

An ideal gas or perfect gas is that gas which strictly obeys the gas law, such that Boyle’s law, Charles law, Gay Lussac’s law, etc.)

  • The size or the molecule of a gas is zero.
  • There is no force of attraction or repulsion amongst the molecule of the gas.
