Amy was sitting outside on a hot, summer day, enjoying a glass of sweet iced tea. She notices some water droplets on the outside of her glass. What is causing those water droplets?
The outside air is heating up the ice, causing it to melt into a liquid.
The cold liquid in the glass is cooling the air around it, making it condense into a liquid.
The outside air is heating up the liquid in the glass, causing it to evaporate.
The liquid in the glass is cooling the air around it, causing it to evaporate.

How can you separate a mixture of iron filings and sand?
By adding water and filtering the mixture.
By heating the mixture until the sand melts.
Using a magnet to attract the iron filings.
By adding acid to dissolve the sand.
Erin pours a mixture of sand and salt into a glass of warm water. She stirs the sand and salt with the water for one minute. She waits a few minutes and looks at the glass. She observes the following:
Which outcome will Erin observe and how could she classify the results of this experiment?
Salt dissolves in the water, while the sand sits at the bottom of the container making the salt and water a homogeneous mixture and the sand sitting at the bottom a heterogeneous mixture.
Salt is transparent in a liquid making it an element.
Salt evaporates from the water making it a heterogeneous mixture.
Salt chemically combines with sand making this a compound.
