Question

6 forms of energy that can be converted to heat energy
mechanical energy choose
choose
friction
fission
nuclear reactions traveling through space
burning wood
light bulb
infrared rays
electrical energy choose
chemical energy
radiant energy
nuclear energy choose
sun choose

Explanation:

• Mechanical Energy to Heat: Friction (mechanical energy from motion is converted to heat via friction, e.g., rubbing hands).
• Electrical Energy to Heat: Light bulb (electrical energy in a bulb is converted to heat (and light), as filaments heat up).
• Chemical Energy to Heat: Burning wood (chemical energy in wood’s bonds is released as heat during combustion).
• Radiant Energy to Heat: Infrared rays (radiant energy in infrared form is absorbed and converted to heat, e.g., sun’s infrared warming objects).
• Nuclear Energy to Heat: Fission (nuclear energy from fission reactions (like in reactors) is converted to heat).
• Sun (Solar Energy) to Heat: Nuclear reactions traveling through space (the sun’s nuclear fusion reactions produce radiant energy that travels to Earth and is converted to heat).

Answer:

• mechanical energy: friction
• electrical energy: light bulb
• chemical energy: burning wood
• radiant energy: infrared rays
• nuclear energy: fission
• sun: nuclear reactions traveling through space
