Transformations
What needs to be added to solid for melting to occur?
Energy or heat because a the particles in a liquid has more energy than the particles ina a solid, which has almost no energy.
What is freezing?
A liquid turning into a solid.
Describe the general density of a solid.
A solid is very dense because the particles are packed together.
What are the main states of matter?
What are solids, liquids, and gases?
Name another state of matter besides solid, liquid, or gas.
You could have said a lot but I'll trust that you said something like PLASMA, BOSE-EINSTEIN CONDENSATE, or COLLOID.
What is condensation?
A gas turning into a liquid.
Of the following, where would evaporation occur.
A. A dark room with a glass of water on the table
B. A puddle of water chilling out in the road on a 90 degree day
C. A puddle of water chilling out in the road on a 90 degree day while its raining.
B. A puddle of water chilling out in the road on a 90 degree day (whats the puddle doing out in the road!?!?! It could get run over!)
What do the particles look like in a solid?
Locked into a set shape and unmoving.
What state of matter is locked into one shape?
Solid
Describe the amount of energy in a solid.
The amount of energy in a solid is little to none. A solids particles don't move and are very compact, so its energy is close to zero.
Burning my failed math test is what type of change? (To the math test on the piece of paper)
Chemical change (kids don't burn your failed math tests. That's lying to your parents.)
What is the freezing point of water?
32 degrees Fahrenheit or 0 degrees Celsius
What do the molecules look like in a liquid?
Spread out and sliding past each other
What state of matter takes the shape of the its container?
Liquid
Describe the amount of energy in a gas.
A gas has a lot of energy because the particles are constantly moving around and away from each other.
What is evaporation?
Liquid turning into a gas.
What is melting?
A solid turning into a liquid.
What do the particles look like in a gas?
They are very spread out and moving freely.
What state of matter expands to fill the whole of its container?
Gas
Describe the amount of energy in a liquid.
The amount of energy in a liquid is a lot more than a solid. The particles move a little bit sliding past each other, so it has a little energy.
Taking a bite out of a delectable cheeseburger is a physical or chemical change? (to the cheeseburger not me)
Physical change (to the delectable cheeseburger)
Solid directly to a gas
Sublimation
Describe the general density of a liquid.
The density of a liquid is not extremely dense because the particles are spread out enough to slide past each other.
What is a plasma? (An example would be sufficient)
Stars etc.
What is a plasma?
Stars etc.
