The tanker
Water/Steam
Anything that has mass or takes up space.
What is matter?
The most tightly packed state of matter.
What is a solid?
What happens when particles cool down?
They sink down/They become more dense
True/False
When you heat up a pot of water, the temperature decreases causing the water to boil.
False
What was in the tanker before it was cleaned?
Air
How tightly packed the molecules in an object are.
A state of matter that spreads out to take the shape of its container/space.
What is gas?
A decrease in temperature, causing a decrease in energy, liquid turns to solid.
How did the pressure in the tanker change so quickly?
A quick change in temperature.
How much space an object takes up.
What is Volume?
When steam cools and changes into a liquid state of matter
What will happen if hot water is placed on top of cold water.
Nothing, their densities are already balanced/where they want to be.
An increase an energy/temperature, causes a liquid to turn into a gas.
What is boiling
During the night what happened to the tanker?
The metal and the air inside the sealed tanker cooled, causing a drop in pressure and the liquid to condense.
The force applied to an object
What is pressure?
A state of matter where particles flow past each other, it takes the shape of its container.
What is liquid?
As steam condenses there are less molecules pushing on the container, this means the pressure ______________?
Decreases
Overnight as the tanker imploded, where was the greatest amount of force exerted on the tanker?
Outside from the air pushing down on the tanker.
Compare density and mass.
Density and mass are similar because the denser the material is, the more mass it will have. The less density something has the more spread out the particles are.
Give an example of a gas condensing.
Answers may vary.
How does a ping bowling ball relate to a volleyball?
Both have the same volume, but different densities. The bowling ball is more dense than the volleyball but they each take up the same amount of space.
What is true about how temperature and pressure are related?
Both of them are proportional, meaning if temperature rises so does the pressure. Reversely if temperature goes down, so does pressure.
