- No inter-particle connections
- What differs them from liquids is the fact that they can move freely without any confines
- Liquids are still connected
- Moves as if it’s a pool ball, it moves in a straight line until it hits something until it is deflected in another direction, then it stays in that direction until it hits something else
- Gas particles are subject to perfectly elastic collisions
- Whenever a gas particles collides with something, they do not gain or lose energy
- Pressure exerted by a gas is due to collisions of gas particles with the container they occupy.
- There are no interparticle attractions
- Means that one water molecule is not attached to another, not that the elements within the molecules are separate
- The volume a gas occupies is considered to be empty space.
- The actual volume of the gas particles is negligible compared to the volume the gas occupies.
- Has to do with the relationship between volume and pressure
- when you assert pressure on a gas, you decrease the volume
- Relationship between volume and temperature (Direct relationship)
- The relationship between pressure and temperature
- The pressure of a fixed mass of gas in a constant volume is directly proportional to the absolute temperature.
Solids that can absorb moisture from the atmosphere
Is the process of absorbing so much moisture a solution forms
- The particles at the surface are pulled together and down into the body of the liquid
It causes a meniscus to form
- The resistance of a liquid to flow
- The strength of the bonds determines how well one layer moves over the one below it
High viscosity= “thick” liquid pours slowly
- Low viscosity= “thin’ liquids pour easily
Liquid vapor at any temp other than the boiling point
The KE in liquids is distributed among particles evenly
Evaporation only occurs at the surface. The most energetic particles do this
Rapid evaporation within the body of the liquid
Ionic Substances- Made up of ions
Molecular Substances- Made up of molecules
partials are arranged in a regular pattern three dimensionally. It creates a specific geometric shapes
No Regular Pattern of Arrangement
If I wanted to collect data about how deep a pond is would I use quantitative or qualitative data?
In science ___________________________ data typically evolves all of the senses except for taste and touch.
When you are making an observation which would be correct?a. Like Wax b. Is Wax
All _______________ digits are significant, zeros between _______________ digits and _______________ zeros (zeros at the end of the number) all others ____________significant
All non-zero digits are significant, zeros between significant digits and trailing zeros (zeros at the end of the number) all others are not significant
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
