Particle Principles
What tiny building blocks make up all matter according to the particle model?
What are particles?
What phase change occurs when a solid turns directly into a liquid?
What is melting?
What is the scientific term for when matter increases in volume as it gets warmer?
What is thermal expansion?
Which is denser: a solid block of iron or air?
What is a solid block of iron?
What lab instrument is used to accurately measure liquid volume in milliliters (mL)?
What is a graduated cylinder?
In this state of matter, particles are tightly packed together and only vibrate in place.
What is a solid?
What process occurs when gas particles cool down, lose energy, and turn back into a liquid?
What is condensation?
What is the scientific term for when matter decreases in volume as it cools down?
What is thermal contraction?
Unlike most other substances on Earth, what happens to water when it freezes into a solid?
What is it expands / becomes less dense?
What temperature measuring tool works directly because liquid inside expands when heated and contracts when cooled?
What is a thermometer?
What happens to the speed of particles when a substance is heated?
What is they move faster?
On the Celsius scale, what is the boiling point of pure water at sea level?
What is 100°C?
Why are small gaps (expansion joints) engineered into concrete bridges and sidewalks in Alberta?
What is to prevent cracking/buckling when concrete expands in hot summer weather?
Why does an ice cube float in a glass of liquid water?
What is because solid water (ice) is less dense than liquid water?
What scale, named after Swedish astronomer Anders, do Canadians use to measure daily temperature?
What is the Celsius scale?
True or False: When you heat matter, the particles themselves grow larger.
What is False?
If you freeze 100 grams of liquid water into solid ice, what is the total mass of the ice?
What is 100 grams?
When air inside a balloon cools down, what happens to the space between the air particles inside?
What is the space between particles decreases (causing the balloon to shrink/contract)?
How does ice floating on top of lakes in winter protect fish and aquatic life beneath it?
What is it forms an insulating blanket on top, keeping the deeper water liquid so life can survive beneath?
Why can water freezing inside cracks in Alberta roads during freeze-thaw cycles create potholes?
What is water expands when it turns into ice, pushing the pavement apart?
Name the two forces or features that keep particles near each other, which weaken as matter is heated.
What are attractive forces
Using particle theory, explain why evaporation happens faster on a hot summer day than on a cold fall day.
What is heat causes water particles to move faster and gain enough energy to break away into gas?
Which state of matter—solid, liquid, or gas—generally expands the most when heated?
What is gas?
If two liquids are poured into a glass and Liquid A settles above Liquid B without mixing, which liquid is denser?
What is Liquid B?
What standard metric (SI) unit is used when measuring mass on a balance scale in a Grade 6 science lab?
What are grams (g) or kilograms (kg)?
