Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.

To overcome the forces of attraction
intermolecular forces of attraction for the liquids and gases
The new pressure changed relative to the original by a factor of 8/3.
<h3>What is the change in the pressure?</h3>
Using the ideal gas equation;
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant
T = temperature
P1 = nRT/V
P2 = 4n * R * 2T/3V
Hence;
P2/P1 = 4n * R * 2T/3V ÷ nRT/V
P2/P1 = 4n * R * 2T/3V * V/nRT
P2/P1 =4 * 2/3
= 8/3
