States of Matter
Out of the three common states of matter, the one with the most kinetic energy.
What is a gas?
Changing from a liquid to a gas
What is vaporization?
One beaker contains 1 liter of water and the second beaker contains 5 mL of water, but both are the SAME TEMPERATURE. This beaker has MORE thermal (total) energy.
What is the one with more water in it (1 liter of water)
It's the type of rock that is formed under extreme heat and pressure.
What is metamorphic?
This is the only substance on Earth that exists in all 3 states of matter in nature.
What is water?
This is the state of matter where attractive forces are strong, particles are pulled close together. Has definite shape and volume.
What is a solid?
This occurs when the temperature of matter goes below its melting point.
What is freeze?
The measure of the average kinetic energy of a substance.
What is temperature?
To determine an unknown substance the thing you should use from these choices: mass, color, volume, melting point.
What is melting point?
What is less air pressure?
What is solid<liquid<gas?
This is the name given to the process when hot water vapor fogs up a cooler mirror.
What is condensation?
Particles at higher temperatures have more _____energy and that's why they are moving so much faster.
What is kinetic?
The electrons responsible for atoms forming bonds with other atoms to create molecules.
What are valence electrons?
When modeling (drawing) the energy and motion in particles on you should use these.
What are arrows? (Longer arrows represent faster particles.)
State of matter where enough intermolecular forces are overcome for freedom of motion with no definite shape, but not enough to allow particles to spread out, so it has a definite volume.
What is liquid?
2 phase changes that involve adding/increasing thermal energy.
What are melting, vaporizing (boiling/evaporating), or subliming.
This is why an iceberg has more thermal energy than a cup of hot water.
What is because it has more particles (atoms, molecules, etc)?
0 degrees Celsius and pressure at sea level are known as this universal measurement.
What is STP (standard temperature and pressure)?
Pressure and this determine the state matter is in.
What is temperature?
Some substances have particles with such strong attractions between their molecules that they don't change phase until temperatures are very high. These substances most exist in this state of matter.
What is solid?
While matter is in the process of changing state the temperature is doing this.
What is remaining constant?
It's 95o F outside your house. The inside of the house is 80o F. You mom suggests opening the windows because it's so hot in the house. You tell her this to explain why she shouldn't open the windows.
What is because hot air flows from warmer to cooler so the outside air will come and make the house even hotter?
The variable that the investigator purposely changes to test a hypothesis.
What is the independent (manipulated) variable?
To make a substance boil at a higher temperature than normal, you should increase this.
What is pressure?
