What are similarities and differences between refraction, reflection, diffraction and absorption?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

The law of reflection states that the angle of reflection is equal to the angle of
