A __________ refers to the process of transition of matter from one state (solid, liquid, gas) to another.
phase change
100
What is this?
Types of precipitation in the winter
100
_______ is anything that has mass and takes up space.
Matter
100
When a phase change occurs from solid liquid to a gas the __________ or __________ changes
volume or density
100
a widely used construction material, starts expanding at 20°C.
Steel
100
Why does ice float?
It is less dense than water
200
This is the process through which a liquid turns into a gas.
Evaporation
200
What type of weather an I? Number 4
Rain
200
The particles are close together. The particles are very strongly attracted to each other.
Solid
200
The space an object takes up
Volume
200
Its expansion begins at a higher temperature, around 35°C, making it a more suitable choice for hot environments.
concrete
200
What temperature is water the most dense?
4 degrees C
300
This is the reverse process of evaporation, where a gas turns back into a liquid.
Condensation
300
What type of weather am I? Number 1
Snow
300
The particles are slightly farther apart. Particles are less attracted to each other and are able to slide past each other.
liquid form
300
No matter how they move, their total _____, or amount of matter, stays the same in a substance.
mass
300
______ begins expanding at a lower temperature, around 15°C, and expands more than steel, concrete, and glass.
Aluminum
300
During summer month the cooler water can be found where?
At the lower depths.
400
This is when a gas changes directly into a solid without becoming a liquid first. An example of this can be seen when frost forms on a window on a cold day.
Deposition
400
What type of weather am I? Number 2
Sleet
400
The particles are far apart and can move in any direction because the attraction forces between them are weak. They have no fixed shape and no fixed volume. They expand to fill their container.
gas form,
400
_________ is a measure of how much 'stuff', or mass, is packed into a certain amount of space, or volume.
Density
400
This material expands depending on it's orientation.
wood
400
During winter months where is the warmer water found
deeper in the water
500
This process involves a substance transitioning from a solid state directly to a gas, skipping the liquid state. An example is the "disappearance" of dry ice (solid carbon dioxide) when left at room temperature.
Sublimation
500
What type of weather am I? Number 3
Freezing rain
500
This is an electrically charged gas. Because _____ particles have an electrical charge, they are affected by electrical and magnetic fields. This is the main difference between a gas and a _______. (Northern Lights)
Plasma
(We did not talk about this you get a free 500 points for picking)
500
________ __ __________ __ _______
states that the total mass of substances doesn't change during a chemical reaction. It means that matter can't disappear or be created out of nothing - it can only change forms.
Principle of Conservation of Mass
500
A common material for roads, _________ can start to soften and expand at around 50°C,
Asphalt
500
If ice wasn't less dense than water what would happen.
Ice would form on the bottom of the lake
