Energy Flashcards
What is the law of conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed, only transferred.
What do thermometers measure?
Thermometers measure temperature in degrees Celsius (°C).
What happens when we heat things?
As we heat things the particles gain more kinetic energy, and vibrate more or faster.
What do renewable energy resources produce?
Renewable resources produce greenhouse gases when built, not when used, and will not run out.
Where can thermal energy can be transferred?
Thermal energy can be transferred by conduction, convection or radiation.
What is conduction
• Particles collide into others when they vibrate.
How does an insulator reduce energy transfer
Most common insulation materials work by slowing conductive heat flow and convective heat flow.
