Question

1. Any object has internal energy due to the particles inside it.

a) Name two types of energy possessed by these particles

b) Which of these energies is strongly linked to a change in state?

Answer 1

for example, the molecules of a \(real\) gas, namely \(not\) an ideal gas, have two type of energy:
1) kinetic energy, since they are always moving
2) potential energy, since they interact each other by means of a potential, like the \(Lennard-Jones\) potential for example

of course, state changes, are related to the changes of the type of the potential of interaction among such molecules

Answer 2

m late.............bt its KE and PE...n change is state is due to PE
