The process by which matter changes from liquid to solid

What is freezing?

100

What you must do with energy to heat a substance

What is add/increase?

100

The state of matter in which particles are far apart and disorganized

What is a gas?

100

The freezing point of water (in Celsius).

What is 0oC?

100

The number one priority of lab procedure, even above getting accurate results.

What is safety?

200

The process by which matter changes from solid to liquid

What is melting?

200

What you must do with energy to cool a substance

What is remove/subtract?

200

This state of matter is achieved by cooling a liquid below its freezing point.

What is a solid?

200

An example of this would be when you have an ice-cold drink outside on a hot summer day, the glass sweats.

What is condensation?

200

The first thing you must do before beginning a lab, as part of safety procedure. Protects your eyes from exposure.

What is putting on goggles?

300

The process by which matter changes from liquid to gas

What is evaporation?

300

The process by which heat is transferred between substances

What is conduction?

300

The force that causes different substances to be in different states of matter, even at the same temperature

What is force of attraction?

300

What water does when it changes from liquid to solid ice, due to the arrangement of molecules in a fixed pattern with empty spaces.

What is expand?

300

The purpose of an experiment is to prove or disprove this

What is a hypothesis?

400

The process by which matter changes from gas to liquid

What is condensation?

400

A substance that heats or cools more quickly, such as metal

What is a conductor?

400

This process occurs naturally to liquid water over time if it is left out, and can be sped up by adding heat energy

What is evaporation?

400

Water vapor that rose into the atmosphere and got cold, it condensed and collected into floating water droplets.

What is a cloud?

400

When designing an experiment, you must do this in order to have valid results. Otherwise, the cause of change may be unclear.

What is controlling/isolating variables?

500

The process by which matter changes from gas to solid

What is deposition?

500

The action by which energy is conducted from a fast particle with high energy to a slow particle with low energy

What is collision/contact/slamming?

500

Solids at room temperature have this kind of attraction, especially when compared to gases

What is a strong force of attraction?

500

The shape water molecules are arranged in when in solid form

What is a hexagon?

500

A second copy of the sample which you are experimenting on that you leave alone and do nothing with. This is done to ensure your results are accurate and usable.

What is a control sample?
