In this experiment, warm water was placed in three beakers. different materials were placed above the warm water. An ice cube was placed above the materials and the time for it to melt was measured.

What questions is this experiment attempting to answer?

• How does the type of matter affect the change in temperature of a substance?

• How does the amount of mass affect the change in temperature of a substance?

• How does surface area affect the change in temperature of a substance?

• How does position affect the change in temperature of a substance?

Why did it take the longest for the ice cube above the cotton to melt?

• cotton is a good insulator

• cotton is a good conductor

• no heat can flow through cotton

• heat easily flows through cotton

Why does a full pot of water take longer to heat to a boil?

• there are more particles that need to speed up

• the particles need to move faster to boil if there is more water

• the water boils at higher temperature
