exam
is a theory that explains the states of matter and is based on the idea that matter is composed of tiny particles that are always in motion
kinetic molecular theory
these particles hold kinetic energy.
kinetic molecular theory
under kinetic molecular theory, in higher temperatures, the particles have more _____
energy
under kinetic molecular theory, whereas in lower temperatures, the particles have less _____
energy
the more _____ a particle has, the faster it’ll move
energy
the more energy a particle has, the faster it’ll _____
move
in solids such as _____, the particles barely move and hold a regular pattern because the energy is low and the particles are tightly packed
ice
compared to solids, ______ have more energy and the freedom to move around.
liquids
what molecules have more energy and the freedom to move around?
liquids
in _____ like steam, these particles have the most energy.
gasses
what particles are sparse and move around freely?
gasses
____ can be expanded and compressed in different pressures and are usually invisible to the eye.
gasses
what is the type of law that provides a relationship between the pressure and the volume of a gas?
boyle’s law
what is the type of law that that provides a relationship between the volume occupied by a gas and the absolute temperature?
charle’s law
what is the type of law that provides a relationship between the pressure exerted by a gas on the walls of its container and the absolute temperature associated with the gas?
gay-lussac’s law
what law gives the relationship between the pressure of a gas and the volume of the gas at a constant temperature?
boyle’s law
what law’s volume of a gas is inversely proportional to the pressure of a gas at a constant temperature?
boyle’s law
what law states that at constant pressure, the volume of a gas is directly proportional to the temperature (in Kelvin) in a closed system?
charle’s law
what law describes the relationship between the temperature and volume of the gas?
charle’s law
what law gives the relationship between temperature and pressure at constant volume?
gay-lussac’s law
what law states that at a constant volume, the pressure of the gas is directly proportional to the temperature of a given gas?
gay-lussac’s law
_____ are sugar molecules
carbohydrates
along with proteins and fats, _____ are one of three main nutrients found in foods and drinks.
carbohydrates
our body breaks down ______ into glucose
carbohydrates
