What is the state of matter where particles are far apart and move freely?
Solid
Liquid
Gas
Plasma
What is the relationship between temperature and particle movement?
Higher temperature means slower particle movement.
Higher temperature means faster particle movement; lower temperature means slower movement.
Temperature has no effect on particle movement.
Lower temperature means faster particle movement.
How do particles move in a gas?
Particles move independently from one another.
Particles are tightly packed and vibrate in place.
Particles move in fixed positions and do not change location.
Particles move in a circular motion around a central point.
What is conduction?
Conduction is the transfer of thermal energy through direct contact between materials.
Conduction is the process of energy transfer through electromagnetic waves.
Conduction refers to the movement of fluids in a circular motion.
Conduction is the transfer of energy through chemical reactions.
What happens to particles when thermal energy is removed?
They move faster and may change state (e.g., liquid to gas).
They move slower and may change state (e.g., gas to liquid).
They remain at the same speed and do not change state.
They move randomly and may change state (e.g., solid to gas).
What is convection?
Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).
Convection is the process of heat transfer through direct contact between materials.
Convection is the transfer of energy through electromagnetic waves.
Convection is the movement of air caused by differences in pressure.
How do particles move in a solid?
Particles vibrate within fixed positions.
Particles move freely in all directions.
Particles slide past each other easily.
Particles are stationary and do not move.
What is the state of matter where particles are tightly packed and vibrate in place?
Liquid
Gas
Solid
Plasma
What is an example of convection?
Warm air rising and cool air sinking in a room.
Water boiling in a pot on the stove.
Ice melting in a glass of warm water.
A fan blowing air across a room.
What is thermal energy?
Thermal energy is the total energy of all the particles in an object, related to their motion and position.
Thermal energy is the energy stored in the chemical bonds of a substance.
Thermal energy is the energy associated with the gravitational pull on an object.
Thermal energy is the energy produced by electrical currents in a conductor.
What is an example of conduction?
The sidewalk burning your bare feet in the summer.
A pot of water boiling on the stove.
Ice melting in your hand.
A fan blowing air on a hot day.
What is radiation?
Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.
Radiation is a type of sound wave that travels through air.
Radiation is the process of cooling an object by removing heat.
Radiation is the movement of particles in a solid state.
What is an example of radiation?
Feeling the warmth of the sun on your skin.
Hearing a sound from a distance.
Seeing a rainbow after rain.
Smelling flowers in a garden.
What happens to particles when thermal energy is added?
They move faster and may change state (e.g., solid to liquid).
They move slower and become more compact.
They remain stationary and do not change state.
They lose mass and become lighter.
What is the state of matter where particles are close together but can slide past each other?
Solid
Liquid
Gas
Plasma
