what is heating in chemistry
The definition of chemistry easy is the study of elements, laws of combination and behavior. The definition of simple is having only one thing or element to do.
the application of the theories and principles of chemistry to practical purposes.
A definition doesn't exist for low density. The values depends on the application or material.
A very short definition is: organic chemistry is the chemistry of carbon compounds. But, by tradition some compounds of carbon are considered inorganic chemicals. Or Organic chemistry is the study of Hydrocarbons or their derivatives

Celsius and Kelvin scales.
Zero Kelvin by definition
uhmm
The scientific definition of chemistry revision is when older chemistry theory is updated to reflect the current theory of chemistry. It is when a scientific formula has to be updated because new information has been found out.
The definition of chemistry easy is the study of elements, laws of combination and behavior. The definition of simple is having only one thing or element to do.
Just by definition in the SI naming convention.
the application of the theories and principles of chemistry to practical purposes.
In Chemistry, K is an abbreviation for Kelvin which is a unit for temperature, but I don't know if that's what you were asking.
This is no chemistry but maybe a mis-spelling of 'H2SO4', in that case rephrase your question.
The Kelvin scale, usually, but chemistry and allied disciplines use Celsius sometimes.
