Kinetic Theory and the Phases

Front

What is the melting point of a substance?

Back

The temperature at which a solid becomes a liquid.

Front

What does a high specific heat mean?

Back

It requires more energy to change the temperature of a substance.

Front

How does heat flow between objects?

Back

Heat flows always from warm to cold.

Front

What is the lowest possible temperature on the Kelvin scale?

Back

Absolute zero, which is 0 K.

Front

Why are low specific heat materials used in cooking skillets?

Back

They change temperature quickly, allowing for faster cooking.

Front

What is kinetic theory?

Back

A theory that explains the behavior of matter in terms of particles in motion.

Front

What are the three phases of matter?

Back

Solid, liquid, and gas.

Front

What happens to particles in a solid?

Back

They are closely packed and vibrate in place.

Front

What happens to particles in a liquid?
