A ______ is a state of matter that has a specific shape and volume.
solid
Matter is made up of very tiny particles called ______.
atoms
the amount of force that is put on an area
Pressure
How to concert kelvin to degrees celsius
K - 273 = °C
A 40.0 L tank of ammonia has a pressure of 12.7 kPa. Calculate the volume of the ammonia if its pressure is changed to 8.4 kPa while its temperature remains constant.
60.5 L
The atoms in a solid are “locked into place”, but they do make small movements called ________.
vibrations
A ______________ happens when matter changes from one physical form to another
change of state
a measure of how fast the particles of an object are moving
Temperature
Charles' law says that volume and temperature are _______ related.
directly (temperature increases, volume increases)
A _______ is a substance that has a specific volume, but has no particular shape.
liquid
Condensation Point
the specific temperature at which the substance changes from a gas to a liquid
how much space an object takes up.
Volume
Boyle’s law says that volume and pressure are _______ related.
inversely (when volume decreases, pressure increases)
a force that acts on the particles at the surface of a liquid to hold them together.
Surface Tension
When energy is added, it is _________, and when energy is removed it is _________.
Endothermic - energy is added
Exothermic - energy is removed
The hotter an object is the _____ the particles move and the ____ energy is added.
faster ; more
__________, __________, and __________ of a gas are all related to each other.
Temperature, pressure, and volume
If a liquid is resistant to flow, it is said to have a _____ _______.
high viscosity
Sublimation
the change of state from solid to gas
