True
Your dad decides to make spaghetti. He goes to the stove and turns it on. How is energy transferred?
Electrical to Thermal
(Remember you know it is electrical because it is a plugged in appliance and stoves and grills are conductors of thermal energy)
Fill in the blank:

True or False:
If solar energy usage has greatly increased in Virginia in the 2000s then we can conclude Virginia is uncovering new ways to move energy through electrical currents.
True (because you can't create or destroy energy)
A fire is being used to make hot tea. What form of energy is being used to boil the water?
Thermal Energy
Electrical Energy
Hydropower plants use water flowing through pipes that then pushes against and turns blades in a turbine that spin to power a generator to produce electricity for homes and businesses. What type of energy transformation is this?
Mechanical (moving water) energy being transferred to electrical energy
Identify the type of energy (radiant, thermal, mechanical, electrical)
Radiant
