States of Matter
What are the three states of matter?
Gas, liquids, soldis
What are the three kinds of heat transfer?
Conduction, convection, and radiation
What particles have the most space between each other?
gases
What is heat?
A type of energy a substance can lose or gain.
Fahrenheit, Celsius, and Kelvin
How are the particles arranged in each state of matter?
Solids- packed closely together, vibrating slightly.
Liquids- have some space between them, have space to move.
Gas- largely spread out and move freely.
What is conduction? Give a definition and an example.
The transfer of heat through molecules and direct contact.
What state of matter contains the lowest kinetic energy?
Solids
What is temperature?
The measure of how hot or cold a substance feels.
What is the boiling point of Fahrenheit and Celsius?
212F
100C
What are three ways that states of matter can change?
Fusion, Evaporation, Condensation, solidification, sublimation, desublimation
What is convection? Give a definition and an example.
Molecules expand an rise when heated and are displaced by cooler particles.
The force of attraction is greatest in what type of matter?
solids
What is kinetic energy?
Energy in motion. Heat is kinetic energy.
What is the difference between sublimation and condensation?
Sublimation is when a solid changes directly to a gas (ex: dry ice). Condensation is when a gas changes directly to a liquid.
sublimation or fusion and vaporization
What is radiation? Give the definition and an example.
The transfer of heat using waves without direct contact.
What does the kinetic molecular theory state?
1. All matter is made up of tiny particles, and those particles are always moving in random directions.
How is the amount of energy a substance has measured? There are two ways.
Joules or calories.
What is fusion?
When heat changes a solid to a liquid.
What processes can change a gas to a solid?
Desublimation or condensation and solidification
conductors and insulators
What will happen to particles if temperature rises?
They begin to speed up and move more frequently.
What do thermometers measure? (More specific than temperature)
They measure the average amount of kinetic energy.
How do the three states of matter relate to the Particle Theory of Matter?
All three states are made up of particles that have space between them, that move and that are attracted to each other.
