Explanation:
The physical properties of matter tells us everything about the substance when no change is occurring to its constituents.
We observe such properties with our senses or instruments or some apparatus.
Examples are boiling point, melting point, density, viscosity, spectroscopic patterns, state of matter, odor, taste, hardness, texture etc
A chemical property is one that tells us what a substance can do with regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water etc.

Answer:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 104 kPa
= final pressure of gas = 52 kPa
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The volume of air at where the pressure and temperature are 52 kPa, -5.0 ºC is .
Answer:
The behaviour of gases is described in terms of kinetic theory , which considers the motion of molecules in the gas . The gas link pressure , volume and temperature .
Explanation:
atom: The smallest possible amount of matter which still retains its identity as a chemical element, consisting of a nucleus surrounded by electrons.
proton: Positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element. It weighs 1 amu.
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
