Why is a solid so orderly? All of the atoms are so closely packed that they are stuck in place vibrating. they still have Kinetic Energy.
What is a liquid? State of matter in which a material has a definite volume but not a shape.
Give an example of how a gas looks in a gas's state of matter. A pool's billiards bouncing off each other.
Is it still considered Kinetic Energy when an object is not moving? Yes.
True or False, pressure is distributed over one area of an object? False, it is distributed over all areas of the object.
At which temperature is something considered Absolute Zero? The temperature at which an object is at 0 Kelvin.
Charles Law decrees what? Volume of a gas is directly proportional to it's temperature in kelvins if the pressure and number of particles are constant.
What does Boyles law decree? Volume of gas is inversely proportional to it's pressure if the temp. and the number of constant is proportional
Give an example of a phase change. Melting, freezing, condensation, sublimation, and deposition are six common phase changes.
How can you remember that endothermic is when a system absorbs energy rather than releases it? Endo means within in Latin.
What is heat of fusion? Melting points for substances.
How can you remember exothermic in comparison to endothermic? Ex means out in latin so energy is being releases or let out
Is vaporization an endothermic or exothermic process? Endothermic.
True or false the heat of vaporization varies from substance to substance True.
Does evaporation take place below or about the surface of the liquid? Above.
When does the vapor pressure of water increase? When the temperature increases.
During condensation does the phase change go from gas to liquid or liquid to gas? Gas to liquid.
Give an example of sublimation. Dry ice freezing.
What is deposition the reverse of? Sublimation.
