what is a solid? liquid? gas? a solid is a state of matter in which materials have a definite shape and a definite volume. a liquid is the state of matter in which a material has a definite volume but not a definite shape. gas has no definite hsape or volume.
what is kinetic energy? give an example. what does it say about kinetic energy and its particles? kinetic energy is the energy an object has due to its motion. a ball being thrown has kinetic energy. "the kinetic theory of matter says that all particles of matter are in constant motion."
how to gasses move? they move around fast and all over the place, scattering nad very fast. there are forces of attraction among the particles of all matter.
what is the kinetic theory of gasses? the constant motion of particles in a gas allows a gas tp fill a container of any shape or size.
explain the behavior of a liquid. 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.
explain the behavior of a solid. solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
what is pressure? pressure is the result of a force distributed over an area.
what is absolute zero? is a temperature of zero kelvins.
what is charles law? states that the volume of a gas is directly proportional to its temperature in kevins if the pressure and the number of the particles of the gas are constant.
boyles law? states taht the volume of a gas is inversly proportional to its pressure if the temperature nad the number of particles are constant.
phase changes? is a reversible pohysical change that occurs when one substance changes to another.
endothermic? its a change when the system of a material absorbs energy from its surroundings.
heat fusion? the amount of energy for water.
exothermic? its a change where the system of a material releases enery to its surroundings.
vaporization? the phase change in which a substance changes from a liquid into a gas.
heat of vaporization? the amount of energy absorbed when a liquid changes into a gas.
evaporation? is the process taht changes a substance from a liquid into a gas at room temperature.
vapor pressure? the pressure caused by the collisions of this vapor
condensation? the phase change in which a substance changes from a gas to a liquid.
sublimation? the phase change in which a substance changes from a solid to a gas or vapor without changing into a liquid first.
deposition? a phase change in which a gas or vapor changes directly into a solid without changing into a liquid first.
