Has neither a definite shape nor a definite volume.
What is a gas.
300
The process of a solid becoming a liquid.
What is melting.
300
If _____ increases ______ also increases.
What is temperature/heat, and energy.
300
45 grams of snow is placed in a pan on the stove, after a short while the snow melts, and after a few minutes all of the snow is gone from the pan. How much mass is present from the original snow? What state of matter is it now?
What is 45 grams and gas.
300
Particles that move freely with no limitations outside of a container.
What is a gas.
400
An ionized gas made of positive ions and free electrons.
What is a plasma.
400
The process of a gas becoming a liquid.
What is condensation.
400
If ______ decreases ______ also decreases.

400
A cup of ice cubes is measured to have a mass of 150 grams. The cup is left outside on a hot day, at the end of the day the cup has a mass of 148 grams. How do you explain the 2 gram difference?
What is evaporation, the 2 grams did not disappear, but rather after the ice melted, some of the water must have evaporated into the surrounding air due to the hot weather.
400
A neon sign is an example of which state of matter?
What is a plasma.
500
The fifth and least encountered type of matter.
What is Bose-Einstein Condensates (BEC).
500
The process of a solid becoming a gas.
What is sublimation.
500
Which has more thermal energy, a tea kettle upon a lit stove, or the water poured from the kettle into a cup.
What is the kettle.
500
A helium balloon measures 22 grams, the balloon is placed in a container of liquid nitrogen (very cold), when the balloon is removed from the container it is half its original size but still has a mass of 22 grams, explain why.
What is conservation of mass. The very cold temperature of the liquid nitrogen caused the gas particles to slow down and move closer together, therefore decreasing the size of the balloon, but the temperature did not change the amount of gas still present in the balloon.
