Particle theory
This is what all matter is made of according to particle theory.
What are tiny particles?
This change of state occurs when a solid becomes a liquid.
What is melting?
Increasing temperature causes particle kinetic energy to do this.
What is increase?
Substances with strong particle attraction usually have these types of melting points.
What are high melting points?
During a state change, the mass of a substance does this.
What is stay the same?
When energy is added to a substance, particles do this.
What is move faster?
This change occurs when a gas becomes a liquid.
What is condensation?
A substance boils when particles have enough energy to become this state.
What is a gas?
This determines a substance's boiling point.
What is the strength of attraction between particles?
This Organ Pumps blood throughout the body.
What is the heart?
When energy is removed from a substance, particles do this.
What is slow down?
During freezing, particles do this.
What is lose energy and move closer together?
This type of energy is the energy of moving particles.
What is kinetic energy?
Strong particle attraction means more energy is needed for this and boiling.
What is melting?
If 50 g of ice melts completely, the liquid water will have this mass.
What is 50 g?
The arrangement of particles in a solid can be described this way.
What is tightly packed in fixed positions?
In this state of matter, particles move fastest and are far apart.
What is a gas?
Evaporation happens because particles do this.
What is gain energy and escape the liquid?
Water boils at this temperature under normal atmospheric pressure.
What is 100°C?
DAILY DOUBLE****
Give an example of sublimation and explain the particle change.
What is dry ice turning directly into carbon dioxide gas because particles gain energy and spread apart?
This theory states that all matter is made of tiny particles that are always moving.
What is Particle Theory?
This process occurs when a solid changes directly into a gas.
What is sublimation?
Explain the effect of adding energy on particle speed and spacing.
What is particles move faster and spread farther apart?
DAILY DOUBLE***
Give a real-world example of condensation and explain why it happens
What is water droplets forming on a cold drink because water vapor loses energy and turns into liquid?
This organelle is known as the "powerhouse of the cell," and its function is to give the cell energy
