Final answer:
There are several factors that can cause the measurement of water boiling point to be incorrect, including impurities in water, altitude effect, equipment calibration, and atmospheric pressure.
Step-by-step explanation:
There are several factors that can cause the measurement of water boiling point to be incorrect. These include:
- Impurities in water: Impurities in water can lower the boiling point of water. For example, salt dissolved in water can lower its boiling point.
- Altitude effect: The boiling point of water decreases as altitude increases. This is because the atmospheric pressure decreases at higher altitudes, which lowers the boiling point.
- Equipment calibration: If the equipment used to measure the boiling point of water is not calibrated correctly, it can give inaccurate readings.
- Atmospheric pressure: Changes in atmospheric pressure can affect the boiling point of water. Higher atmospheric pressure raises the boiling point, while lower atmospheric pressure lowers it.
It is important to take these factors into account when measuring the boiling point of water to ensure accurate results.
