Each morning a teacher makes a pot of coffee and usually makes more than what is needed. The teacher purchased a new pot that has clearly marked measurements. How will the new pot help conserve energy?

• A new pot will make coffee at a slower rate and use more electrical energy.

• The silver pot will use solar energy instead of electrical energy.

• The kettle will transform thermal energy to radiant energy.

• With accurate measurements, the teacher will make the right amount of coffee and use less electrical energy.

Which term describes a way energy can move from place to place?

• Thermal energy

• Electrical energy

• Radiant energy

• Chemical energy

• Mechanical energy
