according to ideal gas equation, PV = nRT
P = pressure of the gas
V = volume of the gas
n = number of moles of the gas
T = absolute temperature of the gas
R = univerasl gas constant
if V and n are constant then it will become charle,s law and it is defined as,
Pressure of the gas is directly proportiona; to the absolute temperature at constant volume and constant number of moles of the gas.
So if pressure increases Tempersture increases and if pressure decreases then temperature decreases.
at sea level the pressure ia 1 atm so the water boils at 100 0C and if you altitude the pressure of atomosphere decreses then boiling temperature of water also decreases and boils at 95 0C.
Answer: B i.e., the atomospheric pressure is less

At sea level, water boils at 100 °C, and the absolute atmospheric pressure is 101 kPa. As the atmospheric pressure above water decreases, the temperature required for boiling also decreases, at a rate of 3.1 kPa per "C. For the system shown below: a. What is the absolute atmospheric pressure at an elevation of 4100 m, assuming a constant unit weight of air of 11.80 N/m3? b. What will be the boiling temperature for water at this elevation?

Problem 8 Because pressure falls with increasing altitude, water also boils at a lower temperature. Consequently, food generally require more time to cook at higher elevations. Determine the boiling temperature of water at sea-level, 1000 m, and 2000 m above sea-level. Assume standard atmospheric conditions.

When a person who lives at sea level travels to a high altitude, they are moving to an area with a lower atmospheric pressure. The number of oxygen molecules in a breath is the same, but there is lower partial pressure of oxygen; thus the lower air pressure results in less diffusion of oxygen into the blood for each breath compared to a breath at sea level. How would this change in oxygen availability affect the person’s heart rate and...

The water in a pressure cooker boils at a temperature greater than 100°C because it is under pressure. At this higher temperature, the chemical reactions associated with the cooking of food take place at a greater rate. (a) Some food cooks fully in 7.00 min in a pressure cooker at 120.0°C and in 70.0 minutes in an open pot at 100.0°C. Calculate the average activation energy for the reactions associated with the cooking of this food. kJ mol-1 (b) How...
