Solid, liquid, or gas
What are the three main states of matter?
Cutting paper
What is a physical change?
Kinetic energy
What is energy due to motion called?
Conduction
What type of heat transfer occurs when you touch something hot?
Gravity
What is the force that pulls objects toward Earth?
Evaporation or Boiling
What is the process called when a liquid turns into a gas?
Flammability or reactivity
What is an example of a chemical property?
Gravitational potential energy
What is energy stored in an object because of its position?
Convection
What type of heat transfer occurs through the movement of fluids?
Friction
What type of force slows down a moving object on a rough surface?
Condensation
What is the term for a gas turning back into a liquid?
Dissolving sugar
What is a physical change example?
Energy cannot be created or destroyed, only transformed.
What does the law of conservation of energy state?
Radiation
What type of heat transfer travels in waves?
An object will stay at rest or in motion unless acted upon by a force.
What is Newton's First Law?
Gas particles
What is move freely and fill their container?
A gas
What is formed when a chemical change produces bubbles?
A rollercoaster going downhill
An example of energy transforming from potential to kinetic energy.
Insulators, such as wood or plastic
What materials are poor conductors of heat?
Force increases
What happens when mass increases?
They slow down and form a fixed structure.
What happens to the particles of a substance as it freezes?
Precipitate
What is the term for a solid that forms from a solution during a chemical reaction?
It remains the same
What happens to the total energy of a system when energy changes form?
It is less dense than cooler air.
What causes warm air to rise in convection?
Force = Mass × Acceleration
