Front

Why is ice less dense than water?

Back

Hydrogen bonds in ice form a crystal lattice structure, causing the molecules to be more spread out and less tightly packed compared to liquid water.

Front

What is specific heat?

Back

Specific heat is the amount of energy required to raise the temperature of a substance by one degree Celsius.

Front

Why does water have a high specific heat?

Back

Water has a high specific heat because it requires a lot of energy to break the hydrogen bonds between water molecules.

Front

What are the products in a chemical reaction?

Back

The products are the substances that are formed as a result of a chemical reaction.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Front

What is density?

Back

Density is the mass of a substance divided by its volume.

Front

How does temperature affect the density of water?

Back

As water warms, it becomes less dense and rises; as it cools, it becomes denser and sinks.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.
