This is the highest frequency most people can hear.
What is 20kHz?
200
This is the force experienced on the top of a branch bending down.
What is tension?
200
Energy goes this direction when melting occurs.
What is "into the system"?
200
More internal energy in one liquid than another of the same volume and heat capacity means it has a higher ____.
What is temperature?
200
This is the inverse of frequency.
What is period.
200
This describes the direction of a sound bending.
What is refraction?
300
Water pressure only depends on this value (other liquids would also depend on the density of that liquid).
What is depth?
300
This is a contraption used to increase the boiling point of water.
What is a pressure cooker?
300
Tile is better at this and so it feels warmer than wood even at the same temperature.
What is thermal conduction?
300
This is the units of frequency.
What is Hertz?
300
This is the kind of interference used in noise cancellation.
What is destructive interference?

What is 1N?
400
Freezing is a ____ process.
What is warming?
400
This is the law of increasing entropy.
What is the 2nd law of thermodynamics?
400
This is the effect to a person if they are moving in relation to another object/person that is vibrating.
What is the Doppler Effect?
400
This is a property of sound nearly every object has (it has to do with resonance).
What is natural frequency?
500
This is the law that describes the pressure in a liquid is the same everywhere.
What is Pascal's Principle?
500
This is the name for the 540 Joules of energy consumed or released for a phase change of 1 gram of water.
What is the latent heat of vaporization?
500
This is the process of going straight from solid to gas.
What is sublimation?
