Matter
What makes up matter
Particles
True or false water expands when heated
True, water expands and takes up more space
What are closer, ice particles or water particles
Ice particles, because they are cold and compacted
What is the freezing point of water in celsius
0 degrees
What happens to particles when heated {scientific word}
Expansion
True or false, ice particles take the shape of a circle
False, the ice particles take the shape of a hexagon
Do particles always have space between them
Yes, no matter how cold they get they always have space in between
What is the boiling point of water in celsius
100 degrees
What is the scientific word for when particles are cooled
Contraction
What are the properties of water
Solid, liquid, gas
True or false particals naturally repel each other
False, the don't repel from each other it is more like an invisible shield separating them
In a thermometer why does the liquid inside of it rise when heated
The particles inside expand and the only room to move is up
What is matter
Something that has mass and takes up space
True or false, water is more dense then ice
True, the liquid form is more dense as water then ice, which is why it floats on liquid as ice
Which state of water has the most kinetic energy, gas, liquid, or solid
Gas, because they are all spread apart
Describe how a liquid thermometer works
When the liquid in the thermometer is heated the only way to expand is up, when it cools the only room to contract is down
True or false, particles are always touching
False the particles never touch each other
True or false, in winter a sheet of ice forms on water protecting animals underneath
True, the ice is like a blanket and it spreads oxygen and nutrients to the animals below
Why is a basketball bouncier when heated
Because the gas particles inside expand making the basketball stretch and giving it more air time
Does water immediately freeze at 0 degrees celsius
No it does not, water will take around 5 minutes before starting to freeze
