Energy
What does KE Stand for?
Kinetic energy

What does a does a chemical reaction need to occur?
reactants or energy
What is Ms. Poulin's classroom themed after?
Star wars
Explain what potential energy is.
Potential energy is the energy due to the distance between particles.
Draw particles with high potential energy.
O)) O)) O))
O)) O))
What state of matter holds a constant shape.
Solid
What is the difference between a chemical change and a physical change?
Physical change usually reversable and no new substance is created ex) chopping wood.
Chemical change is non-reversable, and a new substance is created. Ex) burning wood
What was Ms. Cortez's hair color before it was dyed?
Black
What is the equation for thermal energy?
TE= KE + PE
Describe particle motion of a solid.
Particles vibrate in place and are close together.
What is the phase change called going from gas to liquid?
Condensation
What is the law of conservation of mass?
Total mass before the reaction is the same total mass after the reaction.
*Mass is not created, nor destroyed just recycled
What is Mr. Harris widely known for?
His dad jokes (sometimes on his shirts)
kinetic energy (how fast particles are moving)
Explain how kinetic and potential energy change when you add heat.
Kinetic and potential energy increase when you add heat.
When you increase temperature of a gas what happens to the volume?
What is an exothermic reaction?
Exothermic reaction releases more energy than is used to break bonds
What classroom number has two science teachers?
Room 62
What is the law of conservation of energy?
Energy is not created nor destroyed just transferred
Why can gasses be easily compressed while solids and liquids cannot?
Gasses have particles that are far apart whereas solids and liquids have particles close together.
You need room to squeeze and compress particles together.
What is the difference between boiling and evaporation?
boiling takes place throughout the liquid, turning liquid to gas
Evaporation occurs at the surface of the liquid, turning liquid to gas
An ice pack on a sore ankle is what type of reaction?
Endothermic reaction
Energy is absorbed
What teacher is no longer a science teacher but used to teach science here at Wawona?
Ms. Manhas
