Particle Theory of Matter
What state of matter has particles packed closely together that only vibrate in place?
What is 'Solids'.
What are intermolecular forces?
What are 'forces of attraction between particles'?
What state change happens at 100°C for water?
What is 'boiling, or liquid turning into gas'?
How does freezing rain occur?
What is 'when rain falls through a layer of warm air but lands on surfaces that are cold, forming ice on contact'?
What happens to particles in a substance when it heats up?
What is 'the particles gain energy, move faster, and take up more space, causing the material to expand'?
In which state of matter do particles slide past each other, allowing it to flow?
What is 'Liquids'.
What happens to intermolecular forces in a gas?
What are 'very weak forces that allow particles to move freely'?
What state change is happening when frost forms?
What is 'deposition (gas directly to solid)'?
What is a major impact of freezing rain?
What is 'it creates slippery surfaces and can cause accidents or damage'?
Why is thermal expansion and contraction important in building construction?
What is 'because materials like metal and concrete expand and contract with temperature changes, so structures are designed with flexible joints to prevent cracking or warping'?
What is true about the movement of particles in a gas compared to solids and liquids?
What is 'they move very quickly in all directions'?
What is condensation; what happens to the particles during condensation?
What is 'when a gas cools and becomes a liquid as particles lose energy'?
What state change is the opposite of sublimation?
What is 'deposition?'
What is mass?
What is 'the amount of matter in an object'?
What happens to particles in a substance when it cools down?
What is 'the particles lose energy, move closer together, causing the material to contract'?
Describe the strength of attraction between particles in gases compared to solids and liquids.
What is 'weakest in gases, stronger in liquids, and strongest in solids'?
What is sublimation? Give an example.
What is 'when a solid changes directly to a gas, like dry ice turning into gas'?
What is the freezing point of water?
What is '0°C'?
What is volume?
What is 'the amount of space an object occupies'?
What is one solution used to help the DuSable Bridge when it expanded too much on a hot day?
What is 'hosing it down with cool water'?
What happens to the movement of particles in a solid if it’s heated?"
What is 'they vibrate faster'?
Compare intermolecular forces in solids, liquids, and gases.
What are 'solids have strong forces, liquids have medium-strength forces, and gases have weak forces'?
What is the melting point of ice?
What is '0°C'?
Can two objects have the same volume but different masses? Give an example.
What is 'Yes, for example, a balloon and a rock can have the same size but different masses'?
How does ice help fish and plants survive during winter?
What is 'it prevents heat from escaping too quickly from the water below'?
