Answer:
When the atmospheric pressure is lowers then the boiling point is also lower
Explanation:
The boiling point is reached when the vapor pressure of a liquid matches the atmospheric pressure. Raising the atmospheric pressure will raise the boiling point. Conversely, lowering the atmospheric pressure will lower the boiling point of the liquid.
This phenomena is due to the fact that the vapor pressure of water is temperature dependent. It is raised as temperature increases, and is lowered as temperature drops.
As temperature increases, more particles have enough energy to escape to the gas phase. This increases the vapour pressure. When the vapour pressure equals atmospheric pressure, the liquid boils.
If the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point. Therefore, less heat is required to make the vapour pressure equal to the atmospheric pressure hence the boiling point is lowers
if the atmospheric pressure lowers what affect does it have on the boiling point
Question 3 5 pts What is the boiling point (°C) of water if the atmospheric pressure is 630 mmHg? atmospheric pressure)(0.037 Boiling point correction = (760 mmHg °C/mmHg) & True boiling point = 100 °C boiling point correction 4.8 O 95.2 87.3 96.4
Boiling Point vs. Atomspheric Pressure The boiling point of water depends on atmospheric pressure. At high altitudes, atmospheric pressure is lower, and hence water boils at a slightly lower temperature. Plot a graph by hand for the following data treating atmospheric pressure as the independent variable.
