Thermal Energy and Temperature
As temperature increases what happens to thermal energy?
it also increases
What is crystalline solid?
Materials in which atoms, ions or molecules are arranged in a highly ordered, repeating pattern extending throughout the material.
What is the change in state from a solid to a liquid?
Melting
What is the change in state from a gas to a liquid?
condensation
Charles law is a __________________ Relationship.
Proportional.
Heat moves from _________________ to ___________________ until the particles even out.
Hot to cold.
________________ allows for the surface of water to act like a thin skin.
Surface Tension.
What is the change in state from a liquid to a solid?
freezing
What is the change in state from a liquid to a gas that takes place on the surface of a substance?
Evaporation
Boyles Law is a ________ _________ relationship.
Inversely Propertional
What is temperature?
The measure of the average energy in a substance (how hot or cold it is)
What is an Amorphous solid? Provide an example.
Any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel.
What happens to the energy and temperature in a substance when it melts?
Increases
What is the change in state from a liquid to a gas that takes place within/involving the whole substance? Hint: NOT Vaporization. Be more specific.
Boiling
I took a balloon outside in the winter and it deflated. Which law explains what happened?
Charles Law. Cold temperature made the particles move slower and the volume decrease.
What is thermal energy?
The total amount of energy in a substance due to the motion of its particles
Glass and butter melt unevenly because they are ____________________ Solids.
Amorphous.
What happens to the temperature and energy of a substance when it freezes?
decreases
What happens to the temperature and energy in a substance as it goes through vaporization?
Increases
Boyles law shows a relationship between these two variable.
Pressure and Volume.
Thermal energy is transferred in the form of ____________
Heat
A fluid with high __________ resists motion because its molecular makeup gives it a lot of internal friction.
Viscosity.
What is the change in state from a solid to a gas? What happens to the energy and temperature of a substance going through this?
Sublimation. Rapidy increasing.
What happens to the temperature and energy of a substance as it goes through condensation?
Decreases
Charles law shows a relationship between these two variable.
Volume and temperature.
