Occurs when liquids change to gases rather slowly at the surface of the liquid as heat is added from their surroundings.
What is evaporation?
100
Which of these materials is the best conductor of heat: plastic, metal, or wood.
What is metal?
100
The state of matter where the particles are closest together and move very little.
What is a solid?
200
How much matter is in an object. This can be found using a balance. The more an object has the heavier it will feel.
What is mass?
200
Do not have a definite shape or volume. They take the shape and size of their container.
What are gases?
200
The fast change from a liquid to a gas with bubbles of gas forming in the liquid at a given temperature because a lot heat is being added.
What is boiling?
200
Sources of heat such as fires, stoves, toasters, ovens, the Sun, light bulbs, engines, animals make things warmer and produce______________.

What is heat?
300
When a gas is cooled enough (heat is removed) to form a liquid. An example is when liquid water is visible on the outside of a glass of ice water.
What is condensing?
300
Using electricity eat can be produced. • For example, when electricity is used in light bulbs, heaters, stoves, toasters, or ovens, things get warmer.
