Question 19 - Reading: Level M Practice Test for the TABE Test

According to the passage provided, what is the difference between a simmer and a boil?

Boiling water or other liquids serves a variety of purposes. Boiling refers to the phase change that occurs when a liquid becomes a gas through the application of heat. To boil a pot of water, simply put the pot over a heat source. When small bubbles form and rise to the top, the water is considered to be simmering. When larger bubbles form and rise to the top with frequency, the water is boiling.

The temperature at which boiling happens is called the boiling point. Water boils at around 100°C. When it boils, it transforms into water vapor.

Boiling water can be used to cook food and to kill germs that may be in the water. It can also kill germs on objects that are placed in the boiling water, such as a baby’s pacifier.
