A student wants to investigate what would happen if she stirred 4 different powdered solids into water. To conduct her investigation, she measured 15 g of each substance, stirred them each into their own 200 mL beakers of water, and let them sit for 5 minutes. She recorded her observations from the investigation in the table below. Substance Observations After 5 Minutes F Floated to the top, the water is clear G Sank to the bottom, the water is clear H Sank to the bottom, the water is cloudy J Powder not visible, the water changed color Based on the observation in the table, which powder substance created a solution when stirred in water?
Substance F
Substance G
Substance H
Substance J
A student placed a cup of ice water on his desk and went to lunch. When he returned to his desk after lunch, he noticed that the cup had drops of water on the outside. Which of the following BEST explains why there were water drops on the outside of the cup?
The lights in the room caused the water to evaporate and move to the outside of the cup.
The cup started to sweat as the temperature of the ice in the cup increased.
The water vapor in the room condensed into liquid water on the outside of the glass.
The water in the glass froze and melted on the outside of the glass.
The pictures show tools that can be used for separating mixtures. Select the mixture that is paired with the correct separating tool.
salt and pepper - tweezers
pieces of cork and pebbles - beaker of water
safety pins and iron nails - magnet
sand and iron filings - colander

The picture below shows a pot with a liquid that is being heated on a burner. What would happen if a large amount of cold water were added to the pot?
The water would stop boiling.
The water would increase in temperature.
The water would boil faster because there was more liquid.
There would be no change in temperature.
