Lets look at a certain amount of gas, e.g. trapped
inside a balloon. To completely describe the state of
this gas one has to specify the following quantities:

Q: What is chemistry?
A: The study of matter, its properties and changes at
the atomic and molecular levels.
Chemistry and engineering:
Matter is anything that has mass and occupies space.
There are different forms of energy, e.g.
kinetic energy (when an object moves)
potential energy (e.g. when a spring is extended)
heat ( thats what this chapter is about)
In general, energy is measured in units of Joules (J),
