Introduction

• Molar mass refers to a physical property.
• It is a mass of a particular substance divided by
  the amount of that substance.
• Kg or Mol is the base SI unit of molar mass.
• Molar masses have been express in the form of
  g/mol historically.

Temperature

• This is the numerical measure of cold and hot.
• Temperature is measured by detecting heat
  radiation, kinetic energy particle velocity.
• The most measurement of temperature is the
  thermometric materials behavior.
• It can be calibrated in different temperature
  scales including Kelvin, Fahrenheit and Celsius

Evaluation of molar mass

• Parameters of molecular size have were
  identified.
• They were increasing on the basis of increased
  temperature of the solution.
• Molar mass can change depending on the
  temperature by up to 50 percent.
• Influence of temperature on molar mass is higher
  in elements that have higher molar mass.

• This is usually the case in linear polyethylene
  than in branched polyethylene.
• Influence of temperature on molar mass is also
  noticed in when temperatures are below the normal
  melting point of the normal crystalline polymer.
• Effects of temperature on molar mass can be due
  to the gradual dissociation of aggregates of the
  element and their inter-chaining.
• A relationship is also established between molar
  mass and intrinsic viscosity of elements.
• Effects of temperature on molar mass are
  fractionated when conditions are unfavorable to
  the persistence of the aggregate elements of the
  substance.

Effects of Temperature on Molar Mass in Relation
to Viscosity

• Increased temperatures increase viscosity of
  substances .
• This has also impact on molar mass.
• Effects of temperature are associated with the
  impact that temperature has on diffusion.
• Temperature affects kinetic energy of the
  particles of substances.
• Tiny particles that form any substance called the
  atoms are always moving even when the substance
  is not.

• This is what causes diffusion when substance such
  as gas is left in an open space.
• The rate of diffusion is inversely proportional
  to molar mass.
• This is when temperatures are kept constant.
• It implies that increasing temperatures decrease
  molecular mass.
• This also increases the rate of diffusion.
