The statement(s) that is/are true regarding boiling water is/are:

1. The lower the atmospheric pressure, the easier it is to boil water.
2. It is possible to boil water below 100°C.

These statements are true because when atmospheric pressure decreases, the boiling point of water also decreases. Thus, it becomes easier to reach the temperature required for boiling. Additionally, it is possible to boil water below 100°C by reducing the atmospheric pressure significantly, such as in a vacuum.

The statement "It is possible for water to reach 100°C before boiling" is not true because water reaches its boiling point of 100°C when it starts to boil.

The statement "Water will always boil at 100°C regardless of any environmental conditions" is not true because the boiling point of water can vary depending on the atmospheric pressure.
