Physical chemistry is the area that deals with the
mechanisms, the rate, and the energy transfer that occurs when matter undergoes
a change. So the correct option for the given question is option “B”. Whenever
there is a change in the state of matter, the physical properties definitely
undergo a change. A solid matter will always have a definite shape and volume,
while a liquid has a definite volume but no shape. Gases do not have either definite
volume or shape. Chemical properties might not be affected, but physical
properties are definitely impacted when a matter undergoes change.
CH3CH2OH + 3O2 = 2CO2 + 3H2O
Basically you do trial and error on both sides so they can be equal
