States of Matter
What is matter ?
Anything that has mass and takes up space.
Describe the difference between potential energy and kinetic energy
Potential energy is stored, while Kinetic Energy is in motion.
This type of heat transfer happens when two objects touch
Conduction
Name the 3 states of Matter
Solid , Liquid, Gas
What type of energy is transferred from one object to another through direct contact, like when you rub your hands together?
Thermal Energy
Why does a metal spoon in hot soup become warm?
Metal is strong conductor of heat energy
What properties do all solids share?
All solids have a definite shape and mass
True or False: Energy can be lost and destroyed
False
Name one household object that gives off heat through radiation.
A microwave
What is the primary difference between the movement of particles in a solid, a liquid, and a gas at the molecular level?
The primary difference in the arrangement and movement of particles is in a solid, particles are closely packed and vibrate in fixed positions. In a liquid, molecules are more spread out and can move past each other, but they still have some attraction to each other. In a gas, molecules are far apart and move freely, with little to no attraction between them.
True or False: Flashlights are systems that produce energy in the form of light using electrical and chemical energy.
True

Name and define the 3 forms of heat transfer
Conduction- transfer of heat when in direct contact.
Convection- Heat transfer through air or water
Radiation- transfer of heat through waves
When warm air rises from a heater and spreads through a room, what type of heat transfer is that?
Convection
