What is the difference between insulators and conductors?

What is material that  allows heat & electricity to pass through easily (conductors) and materials that do not allow heat & electricity to pass through easily (insulators) 

200

What specifically is a jacket doing (insulator or conductor) to keep you warmer in the winter (how)?

They act as an insulator slowing down heat from leaving our bodies

Sam builds a ramp and lets a toy car roll down. Describe the energy of the toy car as it rolls down the ramp.
What is kinetic energy increases and the potential energy decreases.
300

Electricity is produced in a hydroelectric plant when moving water turns a turbine. Which describes this energy transformation from the turning turbine into electricity?

What is kinetic energy into electrical energy

300
How do hats help people stay warm in the winter?
What is hats slow down the thermal energy leaving their heads
300

Define mechanical energy and give example 

What is the transformation between KE & PE (juggling, gears turning, etc...)

300
Give an example of a conductor and insulator, not just a type of material
What is up to teacher :)

A student is riding a roller coaster. The roller coaster moves up a hill slowly and then starts to move faster as it goes toward the bottom of the hill. Where on the hill will the student have the MOST kinetic energy?
What is at the bottom of the hill.
400
In certain parts of the world, people use solar panels to harness energy from the Sun to heat their homes. Which type of energy transformation occurs with these solar panels?
What is radiant to thermal energy
400
If you are sitting in the car and the sun in shining down on you, you feel warm because of this type of heat transfer
What is radiation
400

Define sound energy

What is energy that travels as vibrations through matter

400

How much heat is required to raise the temp of 350 g of water from 9.0oC to 12.0oC? (remember the specific heat of water is 4.184 J/g x oC) Q = m x C x ∆T

**Daily Double- (worth double the points)

Q=4393.2 J


500
How does height and distance affect potential and kinetic energy?
What is the increase in height and distance increases the potential energy which then increases the kinetic energy.
500

What is the Law of conservations of energy?

What is energy cannot be created or destroyed, it transforms into other forms of energy

500
During a heat transfer demonstration, students observed water being pumped around a closed loop in an engine. The moving water carries heat from the hot engine to the radiator. Which type of heat transfer is involved when the cooler water absorbs heat while in contact with the hot engine?
What is conduction
500

How much heat is lost when a 220 g piece of copper cools from 567oC, to 18oC?  (The specific heat of copper is 0.38 J/g x oC) Q = m x C x ∆T

**Daily Double (worth double points)

Q= -45,896.4 J
