Describe the States of matter. | Materials can be classified as solids liquids nor gases based on whether their shapes and volumes are definite or vaariable. |
What is a solid? | Solid is the state of matter in which materials have a deffinite shape and a definite volume. |
What is a liquid? | Liquid is the state of matter in which a material has a definite volume but not a definite shape. |
What is a gas? | Gas is the state of matter in which a material has neither a definite shape nor a definite volume. |
What are 2 other states of matter besides.. solid liquid and gas? | plasma, Bose-Einstien condensate. |
What is kinetic energy? | Kinetic energy is the energy an object has due toits motion. |
What is the kinetic theory of matter? | The kinetic theory of matter says that all particles of matter are in constant motion. |
Gases are never at rest why is this? | There are forces of attraction among the particles in all matter. |
Does the constant motion of particles in a gas allow a gas to fill a containor of any shape and size? True or false? | True |
Why does a liquid take the shape of its container? | A liquid takes the shape of its container because particles in a liquid can flow to new locations. The volume of a liquid is constant because forces of attraction keep the particles close together. |
What is the behavior of a solid? | Soids have a definite volume and shape because particles in a solid vibrate around fixed locations |
Do solids vibrate in fixed locations? True or false? | True. |
