fill - in - the - blank
select the correct term from the list below and write it in the blank space. some terms may be used more than once, while others not at all.

1. a ____ is a measurement of electrical power; a unit of electrical measurement equal to the current of one ampere produced by the electromotive force of one volt.
2. the whole heating process of a microwave oven is different because you are ____ atoms rather than conducting heat.
3. a bacterium present in the lower intestine of humans and warm - blooded animals, ____ can cause a life - threatening gastrointestinal infection when it makes its way into food supplies.
4. the continual movement of molecules that occurs when heat accelerates atoms, causing them to break atomic bonds is called ____.
5. to remove any doubt about how to cook popular dishes, some microwaves come equipped with __ __ that are pre - set so the oven cooks foods just right.
6. when the microwave is plugged in, electricity travels through the power cord and enters the machine through its ____.
7. a microwave oven converts the electricity from the wall socket into a high voltage that passes through a ____ that converts it into electromagnetic energy.
8. when a recipe calls for cooking the food for 2 minutes at 50%, or medium power, the oven releases full power waves to cook the food, but for only ____ the amount of time that the food is inside.
9. often, ovens have a \defrost\ button, which is usually programmed according to the weight of the frozen food. the oven begins by using long bursts of continuous waves that ____ as the food thaws.
10. ____ refers to the sparks created when microwaves react to metallic substances inside the oven. sparks can damage the oven or start a fire.

smart buttons
magnetron tube
e. coli
full
decrease
atomic motion
watt
increase
microwave energy
arcing
safety circuits
half
exciting

Explanation:

1. Answer: watt

• Explanation: A watt is defined as a measurement of electrical power, equal to the current of one ampere produced by the electromotive force of one volt.

1. Answer: exciting

• Explanation: Microwaves work by exciting atoms rather than conducting heat.

1. Answer: E. coli

• Explanation: E. coli is a bacterium present in the lower - intestine of humans and warm - blooded animals that can cause a life - threatening gastrointestinal infection when it gets into food supplies.

1. Answer: atomic motion

• Explanation: The continual movement of molecules when heat accelerates atoms and causes them to break atomic bonds is called atomic motion.

1. Answer: smart buttons

• Explanation: Some microwaves have smart buttons pre - set to cook popular dishes correctly.

1. Answer: safety circuits

• Explanation: When a microwave is plugged in, electricity travels through the power cord and enters the machine through its safety circuits.

1. Answer: magnetron tube

• Explanation: A microwave oven converts electricity from the wall socket into a high voltage that passes through a magnetron tube which converts it into electromagnetic energy.

1. Answer: half

• Explanation: When cooking at 50% or medium power, the oven releases full - power waves for half the amount of time the food is inside.

1. Answer: decrease

• Explanation: When defrosting, the oven starts with long bursts of continuous waves that decrease as the food thaws.

1. Answer: arcing

• Explanation: Arcing refers to the sparks created when microwaves react to metallic substances inside the oven, which can damage the oven or start a fire.

Each answer is based on the description provided in the fill - in - the - blank statements. Definitions and functions related to microwaves, electrical power, bacteria, and atomic processes are used to determine the correct terms from the given list.

Answer:

1. watt
2. exciting
3. E. coli
4. atomic motion
5. smart buttons
6. safety circuits
7. magnetron tube
8. half
9. decrease
10. arcing
