States of Matter
What is the shape of a solid?
A solid has a definite shape.
What is melting?
Melting is the phase change from solid to liquid.
What is Boyle's Law?
Boyle's Law states that when volume decreases, pressure increases.
What happens to particles when thermal energy is added?
When thermal energy is added, particles move faster and may change phase.
What are the smallest particles of matter called
molecules
What is the volume of a liquid?
A liquid has a definite volume but takes the shape of its container.
What is condensation?
Condensation is the phase change from gas to liquid.
What happens to gas volume when temperature increases?
Gas volume increases when temperature increases.
How does removing thermal energy affect a liquid?
Removing thermal energy can cause a liquid to freeze into a solid.
What is the particle arrangement in a gas?
In a gas, particles are widely spaced and move freely.
What is vaporization?
Vaporization is the phase change from liquid to gas.
Describe what happens to a balloon when heated.
When heated, the balloon expands as the gas inside increases in volume.
What is the effect of heating on gas particles?
Heating causes gas particles to move faster and occupy more space.
What is Mrs. McGill's sons' name
Liam
Give an example of a liquid.
answers will vary
What is sublimation?
Sublimation is the phase change from solid to gas.
What does Charles's Law state?
Charles's Law states that when temperature increases, the volume of a gas increases.
How does cooling affect particle motion?
Cooling slows down particle motion.
What happens to particles in a solid?
Particles are tightly packed and vibrate in place.
Describe deposition in your own words.
Deposition is when a gas changes directly to a solid without becoming a liquid.
How does pressure relate to gas volume in Boyle's Law?
In Boyle's Law, as pressure increases, volume decreases, demonstrating an inverse relationship.
Describe how thermal energy affects phase changes.
Thermal energy determines the phase of a substance; adding energy can cause melting or vaporization, while removing energy can cause freezing or condensation.
