Jack had a beaker of warm water filled to the 50 ml line. He measured 20 mg of salt using a triple beam balance and added it to his beaker of warm water. Jack stirred using a spoon. After a short time, the salt disappeared. What happened?

• The salt dissolved.

• The salt evaporated.

• The salt condensed.

• The salt changed it's chemical make up and became water.

Rishabh wanted to know if a penny would conduct electricity. He conducted the experiment seen in the image. The light bulb lit up when the penny was touched with the wire from the battery and the wire from the light bulb.

(Choose the best answer)

• Therefore, the penny is an insulator.

• Therefore, the penny is a conductor.

• Therefore, the penny is magnetic and copper.

• Therefore, the penny is not important the battery is the most important.

If a gas is forced into a container, (think about a balloon) it will:

• Fill the space

• sink to the bottom

• Condense and create liquid
