IPC Unit 3

IPC Unit 3 Learning Statements Nuclear Reactions

QuestionAnswer
Two types of nuclear reactions: Fission and Fusion
can be used to produce energy and to conduct medical tests. Nuclear reactions
reactions split the nucleus of an atom. Fission
reactions join two smaller nuclei to make an atom with a larger nucleus. Fusion
nuclear reactions use a large unstable isotope bombarded with high speed particles to split the atom. Example: Uranium 235 Fission
nuclear reactions use two low mass isotopes to join together under extreme pressure and temperature. Example: Tritium H3 , Deuterium H2 Fusion
Currently require more energy to force atoms together than the energy that is produced. fusion nuclear reactors
Currently rely on fission reactions to produce high amounts of energy. nuclear reactors
The sun undergoes __________________ and releases LARGE amounts of energy. fusion nuclear reactions

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
