• Sponge, bottle cap, water, coin

• Coin, water, bottle top, sponge

Answer explanation

Less Dense than water- Object Floats
More Dense than water - Object Sinks

Which liquid is most likely vegetable oil? Why?

• Liquid M, because vegetable oil is less dense than water and more dense than a coin

• Liquid L, because vegetable oil is less dense than water and more dense than a sponge

• Liquid M, because vegetable oil is more dense than water and less dense than a coin

• Liquid L, because vegetable oil is more dense than water and less dense than a sponge

Answer explanation

Less Dense than water- Floats
More Dense than water - Sinks

In an investigation hot water is poured into a clear plastic cup. Another clear plastic cup is placed upside down over the cup of hot water.

• The hot water will become hotter because the air and heat are trapped in the top cup.

• The water level will rise in the bottom cup because of evaporation.

• Water droplets will form on the inside of the top cup as the water vapor cools.

• Water from the bottom cup will become solid as the hot water cools.

Answer explanation

Heat causes change.
