Question | Answer |
---|---|
matter that does not have a definite volume or shape;the particles move very quickly. | Gas |
The ability of a substance to dissolve when mixed with another substance. | Solubility |
determines whether one substance will sink or float in another. Less dense = float More dense = sink | Relative Density |
an object will float in water if its tiny particles are loosely packed & far apart. | Buoyant |
the solid state of water | Ice |
matter with definite volume & no definite shape | Liquid |
the change in the state of water from a water vapor to a liquid | Condensation |
the amount of space that matter takes up | Volume |
Two factors that affect how quickly water evaporates. | Heat & Temperture |
a change in the state from a liquid to a solid Water changes at : 0 degrees Celsius | Freezing Point |
changes in which the form or shape of a substance changes but the substance keeps it's identity | Physical Change |
a change in the state from a solid to a liquid Water boils at : 100 Degrees Celsius | Boiling point |
The amount of matter in something | Mass |
anything that has mass and takes up space; it has properties and can change form | Matter |
matter with a definite volume and shape; the particles are close to one another | Solid |
A measure of the energy of motion of the particles in a substance | Tempeture |
the ability of an object to attract to iron or steel | magnetic |
property used to describe how something feel | texture |
property used to describe how something shines in the light | luster |
gas state of water | water vapor |
when a solid changes to a liquid | melting |
when a liquid changes to a solid | freezing |
an object will sink in water if it's tiny particles are close are close together | density |
describe the object as a solid, liquid, or gas | state |

eye wear that protect the eyes | safety goggles |
a device used to measure time | timing device |
an instrument used to measure an objects mass | triple beam balance |
can not be created or destroyed | energy |
the energy in an object due to the position of an object | mechanical |
the energy of moving particals that produce heat | thermal |
is the form of energy that can be seen | light |
the energy that can be heard caused by vibrations | sound |
objects that allow almost all light to pass through | transparent |
objects that allow some light to pass through | translucent |
objects that allow no light to pass through | opaque |
