Which of the following statement(s) is/are true regarding boiling water?
The lower the atmospheric pressure, the more difficult it is to boil water.
The lower the atmospheric pressure, the easier it is to boil water.
It is possible to boil water below 100°C.
It is possible for water to reach 100°C before boiling.
Water will always boil at 100° regardless of any environmental conditions,
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.
Out of the given statements:
Statement 1: The lower the atmospheric pressure, the more difficult it is to boil water.
This statement is true. As atmospheric pressure decreases, the boiling point of water also decreases, making it more difficult for water to reach its boiling point.
Statement 2: The lower the atmospheric pressure, the easier it is to boil water.
This statement is false. As mentioned in the previous statement, as atmospheric pressure decreases, the boiling point of water decreases, but it also becomes more difficult for water to reach its boiling point.
Statement 3: It is possible to boil water below 100°C.
This statement is true. Under certain conditions, such as high altitudes where atmospheric pressure is lower, water can boil below its usual boiling point of 100°C.
Statement 4: It is possible for water to reach 100°C before boiling.
This statement is false. Water reaches its boiling point of 100°C when it starts to boil. It does not reach this temperature before boiling.
Statement 5: Water will always boil at 100°C regardless of any environmental conditions.
This statement is false. The boiling point of water is dependent on environmental conditions such as atmospheric pressure, altitude, and presence of solutes. These factors can cause the boiling point to vary from 100°C.
