States of matter
This state of matter has a fixed volume but takes the exact shape of whatever container you pour it into. .
What is a liquid?
A pot of water is heated on a stove. Name two types of heat transfer occurring and give an example of each.
What is conduction and convection?
What is a compound?
Through this process, plants release excess water vapor into the air, acting much like how humans sweat to stay cool.
What is a Transpiration?
A plant has vascular tissue, produces seeds in cones, and does not produce flowers. Classify it as specifically as possible.
What is a Gymnosperms?
Dew forming on grass in the early morning is a perfect example of this process, where a gas cools down and turns back into a liquid.
What is condensation?
A metal spoon becomes hot after sitting in a pot of soup. Explain how the heat reached the handle.
Conduction transferred heat through the metal spoon.
Salt water contains substances physically combined but not chemically bonded. What is it?
What is a Mixture?
What is a stomata?
Which group has one cotyledon, parallel leaf veins, and usually fibrous roots?
What is Monocots?
Because the particles in this state of matter are spread very far apart with lots of empty space between them, it can be easily compressed.
What is a gas?
You feel heat from the Sun even though space has almost no matter. What type of heat transfer is this?
What is radiation?
A student mixes iron filings and sand. Is this a compound or mixture, and how could the substances be separated?
What is Mixture? Iron can be removed by magnet
What process releases energy from glucose inside plant cells?
What is Cellular respiration?
A flowering plant has branching leaf veins, a taproot, and two cotyledons. How should it be classified?
What are Dicots?
Adding this type of energy to a block of ice causes its particles to vibrate faster and faster until the crystalline structure breaks apart.
What is thermal energy (or heat)?
Warm water rises while cooler water sinks. What type of heat transfer causes this movement?
What is convection?
Is CO₂ an element, compound, or mixture? Explain why.
What is a compound? carbon and oxygen are chemically bonded.
A plant's stomata close during a very hot, dry day. Which plant process will be directly reduced, and why might closing the stomata help the plant?
What is transpiration? It helps reducing water loss.
A plant produces flowers, and its seeds are protected inside a fruit. What group does it belong to?
What is Angiosperm?
What is plasma?
What type of heat transfer happens when two objects are touching?
What is Conduction?
Salad, trail mix, and muddy water are all examples of this, because the different parts are physically combined and can be separated easily.
What are mixtures?
A plant has flowers, two cotyledons, and branching veins. Is it a monocot or dicot, and is it an angiosperm or gymnosperm?
What is Dicot and angiosperm?
