States of Matter
Name the 4 states of matter.
Solid, Liquid, Gas, and Plasma
Liquid to Solid.
Freezing
What is kinetic energy?
Energy of movement or motion
Condensation
What is the temperature that a solid changes to a liquid?
Melting Point
What is the volume and shape of a solid?
Definite; Definite
Gas to Liquid.
Condensation
Which state of matter has the highest kinetic energy - Solid, liquid, or gas?
Gas
Popsicle sitting out in the sun
Melting
The name of the properties of a solution that change depending upon the total concentration.
Colligative Properties
What is volume and shape of a liquid?
Definite; Indefinite
Liquid to Gas.
Evaporation
From gas to solid, did kinetic energy increase or decrease?
Decrease
Leaving a cup of water on the counter for several days
Liquid to Gas (Evaporation)
What is the freezing/melting temperature of water?
32 F /0 C
What is the volume and shape of a gas?
Indefinite; Indefinite
Solid to Liquid.
Melting
Which state of matter has the lowest kinetic energy?
Solid
Making ice cubes
Liquid to Solid (Freezing)
What is the temperature that water changes to a gas?
212 F / 100 C
How are plasma particles arranged?
Spread out and charged
Solid to Gas.
Sublimation
How does thermal energy affect kinetic energy?
Increased thermal energy equals increased kinetic energy. Decreased thermal energy equals decreased kinetic energy.
Dry Ice
Solid to Gas (Sublimation)
Why is melting/freezing point the same?
Depends on the direction of thermal energy - endothermic or exothermic
