U2: Nuclear Fusion Review

Which star will burn hydrogen the fastest in Nuclear Fusion?

• white dwarf

• medium mass yellow star

• large size but small mass red star

• very massive and large blue star

In nuclear fusion, smaller atoms are forced together to create larger atoms. Does this process release, absorb or maintain energy?

• Absorb energy
• Maintain energy
• Release energy

What are the products of a nuclear fusion reaction?

• A new element

• A new element plus mass

• A new larger element plus energy

• A new smaller element plus energy

When hydrogen is "fused" together on the Sun, what new element is created?

• Helium

• Carbon Dioxide

• Oxygen

• Light

along with new heavier elements the process of nuclear fusion also creates what

• energy
• matter
• quizizz tests
• life

a red supergiant can fuse nuclei into heavier elements BUT it stops at this element

• gold

• silver

• iron

• plutonium

any heavy element (larger than iron) is created by

• supernova explosions

• planetary nebula

• main sequence fusion

• red giants

Do all stars make energy through fusion?

• Yes
• No
• Just our sun
• Only large stars

Very high temperature and pressure is required for:

• Fission
•  Fusion
• Radioactive Decay

Where does fusion occur naturally? SELECT ALL ANSWERS THAT APPLY.

• Underwater
