States of Matter
What are the states of matter?
What is a solid, liquid, gas?
What state of matter is steam?
What is a gas?
Which has a higher viscosity, honey or water.
Honey.
This occurs when a gas moves to a liquid state of matter.
What is condensation
why do liquids expand more than solids?
Particles move around each other faster where the force of attraction between these particles is less than the force of attraction in solids.
Which state of matter is an ice cube?
What is a solid?
What is MATTER?
Watch this video https://www.youtube.com/watch?v=ZgTTUuJZAFs then answer this question:
How does the molecules behave, in a balloon, placed in liquid nitrogen?
The volume of the air decreases.
How may states of matter can we observe in a hot bowl of soup? Explain
3. Solid is the bowl. Liquid is the soup. Gas is the steam.
define sublimation
solid to gas
How do solids molecules move?
They vibrate (shake back and forth) and are close together.
Which state of matter keeps its volume and its shape when you move it from place to place?
What is a solid?
On cooling, the different states of matter contract where their volume decreases. True or false
true
name the six phase changes (transitions)of matter
melting, freezing
Evaporation, condensation
Sublimation, deposition
SLIME is technically not a solid nor a gas. It is called a non-Newtonian fluid. Why?
Because it has properties (acts like) both a solid and a liquid.
fire burning is a physical change or chemical change?
What is a chemical change
Ice melting is a chemical change or a physical change?
What is physical change.
name four characteristics of a solid
Rigid, Fixed shape, Fixed volume, cannot be squashed( compressed)
name the four characteristics of liquid
Not rigid( semi loosely packed)
no shape
fixed volume
cannot be squashed( compressed)
Two things that can change the particle arrangement in matter are called
pressure and temperature
Name matter with no shape and no defined volume. Plus two other characteristics.
What is a gas? Two other characteristics: can be squashed(compressed) and not rigid(very loosely packed.
what phase change happens when a chocolate bar sits in the sun
Melt.
Clouds are made of this.
What are droplets of water.
Dew droplets on the grass on a sunny morning after a cool night is an example of...
Condensation.
Give an example of something SOLID that can be poured like a LIQUID without heating it up.
Sand, sugar, salt, powdered spices, powdered coco, etc.
