What do you think happens when waves hit an object or hit each other?

What does happen, though is that waves can either add up or cancel each other out as they pass through one another. This property is called superposition. If a crest from one wave happens to line up with the trough of another, they cancel each other out. This is called destructive interference.

Explanation:    

When two objects collide and undergo a partially inelastic collision (so every one we experience in every-day life), they rebound to a certain degree, but kinetic energy is not conserved. Thus, the energy of motion must be converted to another type of energy. Thus, when two object collide, the most common forms of energy that kinetic energy is converted to are sound energy and thermal energy.

gas and liquid

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
