Answer 3

This is something which produces or makes heat energy

Question 4

Thermal/heat energy

Answer 4

This is something which produces or makes heat energy

Question 5

Chemical potential energy

Answer 5

Is something which contains chemicals

Question 6

Nucleaur energy

Answer 6

This is something which is nucelaur

Question 7

Elastic p energy

Answer 7

Is energy stored in an object when it is stretchy

Question 8

Energy measurement?

Answer 8

Is in joules

Question 9

Energy transfering

Answer 9

Energy can be transferred (moved from one system to another) or transformed (changed from one form to another).
Energy Chain Example:
• Chemical energy (from food) → Kinetic energy (movement of muscles) → Thermal energy (heat generated from body movement).

Question 10

How to calculate energt effeciancy

Answer 10

Enerfy efficiancy =useful energy output/total energy output x 100

Question 11

Temperature vs. Thermal Energy

Answer 11

Temperature: A measure of the average kinetic energy of the particles in a substance.
• Thermal Energy: The total energy (kinetic + potential) of the particles in a substance.

Question 12

Conductors vs. Insulators

Conducters

Answer 12

Conductors: Materials that allow heat to flow easily.
• Example: Metals (like copper and aluminum).
• Insulators: Materials that resist heat flow.
• Example: Wood, plastic, rubber.

Question 13

Heat Transfer Methods

Answer 13

1. Conduction: Transfer of heat through direct contact.
   • Example: A metal spoon heating up in a pot of hot soup.
   
   2. Convection: Transfer of heat through the movement of fluids (liquids and gases).
      • Example: Warm air rising and cool air sinking in a room.
   3. Radiation: Transfer of heat through electromagnetic waves.
      • Example: The warmth felt from sunlight or a campfire.

Question 14

Renewable energy sources. And no renewable sorces

Answer 14

Renewable Energy Sources: Sources that can be replenished naturally over time.
• Examples: Solar energy, wind energy, hydroelectric energy, geothermal energy, and biomass.
• Non-Renewable Energy Sources: Sources that cannot be replenished on a human timescale.
• Examples: Coal, oil, natural gas, and nuclear energy.
