Fluids
What is the force that pushes a fluid downward because of gravity?
Pressure
All matter is made up of
Particles
What is a conducter
Something that allows heat to move through it
What is the strongest type of bridge
Truss
What is a food web
A network of food chains
Fluids can be either liquids or this other state of matter.
Gass
Matter is anything that has mass and takes up stuff.
Space
What happens to the speed of particles when heat is added to a substance?
They move faster and spread out more
If I wanted to build a bridge over a 40-meter river, what bridge would I make
Arch
What is a decomposer
Orgainsims that break down stuff
This word describes how thick or sticky a fluid is when it flows.
Viscosity
Water changing from a liquid to a gas is called this.
Evaporation
What is the difference between thermal energy and temperature?
Temperature is how hot or cold something is, whereas thermal energy is what we use.
This type of bridge uses cables hanging from tall towers to hold up the road.
Suspension bridge
These are the non-living parts of an ecosystem, such as sunlight, water, and temperature.
Abiotic factors.
This happens when an object floats because the fluid pushes upward on it.
Buoyancy
This process happens when a solid changes directly into a gas without becoming a liquid first.
Sublimation
This type of heat transfer happens when heat moves through a solid by direct contact between
Conduction
This force pulls materials apart in a structure or bridge.
Tension
Organisms like plants and algae that make their own food using sunlight are called this.
Producers
This scientist discovered the principle that explains why objects float or sink in fluids.
Archimedes
This layer of Earth is the hottest and is mostly made of iron and nickel.
The core
How does a thermos flask maintain the temperature of a liquid kept in it?
By using a double-walled mechanism
This type of bridge uses a curved structure that pushes weight outward into supports.
Arch bridge
This process happens when plants use sunlight, water, and carbon dioxide to make their own food and release oxygen.
Photosynthesis
