What are the three main states of matter?
solid, liquid, gas
plasma
foam
mist
Which state of matter has a definite shape and volume?
Solid
Plasma
Gas
Liquid
What happens to the particles in a solid when it melts?
The particles in a solid break apart and form gas when it melts.
The particles in a solid lose energy and become stationary when it melts.
The particles in a solid expand but remain tightly packed when it melts.
The particles in a solid gain energy, vibrate more, and move freely when it melts.
What is the process called when a gas turns into a liquid?
Precipitation
Evaporation
Condensation
Sublimation
How do particles behave in a gas compared to a solid?
Particles in a gas move freely and are far apart, while in a solid, they are closely packed and vibrate in fixed positions.
Particles in a gas are stationary and closely packed.
Particles in a solid move freely and are far apart.
Particles in a gas are tightly packed and vibrate in place.
What is the term for the change from liquid to gas?
Sublimation
Condensation
Freezing
Vaporization
How does temperature affect the motion of particles?
Particles move faster at lower temperatures and slower at higher temperatures.
Higher temperatures increase particle motion; lower temperatures decrease it.
Higher temperatures decrease particle motion; lower temperatures increase it.
Temperature has no effect on particle motion.
What state of matter has particles that are far apart and move freely?
Plasma
Solid
Liquid
Gas
What happens to the temperature of a substance during a change of state?
The temperature fluctuates during a change of state.
The temperature increases during a change of state.
The temperature decreases during a change of state.
The temperature remains constant during a change of state.
What is the process called when a solid turns directly into a gas?
Sublimation
Melting
Evaporation
Condensation
In which state of matter do particles vibrate in fixed positions?
Gas
Solid
Plasma
Liquid
What effect does increasing temperature have on the kinetic energy of particles?
Kinetic energy of particles is only affected by pressure, not temperature.
Increasing temperature decreases the kinetic energy of particles.
Temperature has no effect on the kinetic energy of particles.
Increasing temperature increases the kinetic energy of particles.
What is the term for the change from solid to liquid?
Melting
Condensation
Sublimation
Freezing
How do particles in a liquid compare to those in a gas?
Particles in a liquid are larger and heavier than those in a gas.
Particles in a liquid are closer together and can move past each other, while particles in a gas are far apart and move freely.
Particles in a liquid are far apart and move freely, while particles in a gas are closer together.
Particles in a liquid are fixed in place and cannot move, while particles in a gas are tightly packed.
What happens to the volume of a gas when it is compressed?
The volume of a gas decreases when it is compressed.
The volume of a gas fluctuates randomly when it is compressed.
The volume of a gas remains the same when it is compressed.
The volume of a gas increases when it is compressed.
