Phases of Matter
The phase of matter with no definite shape OR definite volume
What is a gas?
The phase that exists along the x axis in a phase diagram
What is gas or vapor?
According to kinetic molecular theory, attractive forces are greatest for particles in this phase.
What is solid
This property of a gas increases as temperature increases.
What is volume?
Gases behave most ideally under these conditions.
What is high temperature and low pressure?
The phase of matter in which particles have the least potential energy possible
What is a solid?
In this process vapor in the air becomes a liquid
What is condensation?
According to kinetic molecular theory, particles exhibit this type of motion
What is rapid, random motion in a straight line
A sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 L to 15 L. This is the final pressure.
What 0.67 atm?
An explanation of how particles in matter behave
What is kinetic molecular theory?
The phase of matter with the most thermal (kinetic plus potential) energy
What is a gas?
The phase change(s) that occur(s) at 0 degrees Celsius in water.
What is melting and freezing?
Based on kinetic molecular theory this state of matter is affected most by changes in temperature, pressure, and volume
What are gases?
What property(ies) of gases decrease(s) as temperature decreases?
What is pressure and volume?
Vaporization that only takes place at the surface of a liquid
What is evaporation?
The phase of matter a substance would end as after the process of condensation.
What is a liquid?
The pressure and temperature at which solid, liquid, and gaseous phase coexist in equilibrium.
What is the triple point?
According to kinetic molecular theory, particles collide with this type of collision in which no energy is lost.
What is an elastic collision?
This is the amount of gas in moles that occupies 36.52 L at 68.0 °C and 672 mm Hg.
What is 1.15 atm?
The force that pulls adjacent parts of a liquid’s surface together, decreasing surface area to the smallest possible size
What is surface tension?
The phase of matter a substance will end up as at the end of the process of deposition
What is a solid?
In this process matter changes from a solid to a gas, skipping the liquid state
What is sublimation?
According to kinetic molecular theory, the rate of this property is millions of times slower in solids than in liquids
What is diffusion.
This is the mass in grams of carbon dioxide that is contained in a 5.33 L vessel at 48 °C and 1.44 atm?
What is 12.8 g?
A tank containing both HF and HBr gases developed a leak. This is the ratio of the rate of effusion of HF to the rate of effusion of HBr.
What is 2.01?
