Question | Answer | | |
the flow of electricity around a circuit | current | | |
to melt, make a solution out of, or turn into a liquid | dissolve | | |
energy produced by the movement of electrons | electric energy | | |
what is needed to do work or cause change | energy | | |
a push or pull that causes an object to move, stop, or change direction | force | | |
the temperature at which a substance changes states from a liquid to a solid (freezing point of water is 0 degrees Celsius) | freezing point | | |
the temperature at which a substance changes states from a solid to a liquid | melting point | | |
a state of matter with no definite shape or volume | gas | | |
energy that causes a change in temperature between materials | heat energy | | |
to slow down or stop electric current or heat from flowing | insulate | | |
radiant energy that our eyes can see from the visible part of the electromagnetic spectrum | light energy | | |
matter that has a definite volume but no definite shape | liquid | | |
matter that has a definite volume but no definite shape | magnetism | | |
the amount of matter in an object | mass | | |
energy produced by a machine or moving part | mechanical energy | | |
a combinations of two or more substances where each keep their own properties and can be easily separated | mixture | | |
appearances of an object including color, size, shape | physical properties | | |
energy waves bounce off the surface of an object (mirrors or echoes return energy back to their source) | reflect | | |
energy waves bend (change direction and speed) as they pass from one type of object to another type | refract | | |
objects that are more dense sink in water; less dense objects float in water | relative density | | |
a form of matter that has a definite shape and volume | solid | | |
a mixture of one substance dissolved evenly in another | solution | | |

relating to heat | thermal | | |
energy that causes a transfer of heat between materials | thermal energy | | |
measurement of the ability of a solid to dissolve in a liquid | solubility | | |
the physical forms of matter, which include solid, liquid, and gas | state of matter | | |
the temperature at which a substance changes states from a liquid to a gas (the boiling point of water is 100 degrees Celsius) | boiling point | | |
to allow electric current or heat energy to flow through easily | conduct | | |
