Why does water boil faster in the mountains than the city?
Water boils faster in the mountains because the air pressure is lower at higher altitudes. Lower air pressure reduces the boiling point of water, causing it to reach boiling temperature faster than at sea level where air pressure is higher.
When something goes from a solid directly to a gas what is it called?
The process of a substance changing from a solid directly to a gas is called sublimation. This occurs when the substance's vapor pressure exceeds its atmospheric pressure at a certain temperature, allowing it to transition from a solid state to a gaseous state without passing through the liquid phase.
Which graph shows the pressure temperature relationship expected for an ideal gas?
The ideal gas law states that pressure is directly proportional to temperature when volume and quantity of gas are constant. Therefore, a graph showing pressure on the y-axis and temperature on the x-axis with a linear relationship would represent the pressure-temperature relationship for an ideal gas.
What direction do gas particles travel?
Gas particles travel in all directions, bouncing off each other and their container walls. The direction of their movement is random and depends on various factors such as temperature, pressure, and volume.
What happens to the temperature if the pressure of a gas increases?
The pressure increases.
Atmospheric pressure goes on a downward direction only?
No
Does atmospheric pressure goes on downwards direction only?
no, it acts in all directions
Sound is a longitudinal wave What does the word 'longitudinal' mean?
It means the disturbance (e.g., pressure difference) goes in the same direction as the direction of the wave. In a transversal wave, on the other hand, the disturbance goes at a right angle.It means the disturbance (e.g., pressure difference) goes in the same direction as the direction of the wave.

Does the chamber of a barometer expand or contract as the air pressure goes up?
The chamber of a barometer will contract as air pressure goes up. A rise in air pressure pushes the mercury column downward, causing the chamber at the top to become smaller.
What role does atmospheric pressure play when someone is drinking a liquid through a straw?
when you drink through a straw you remove some of the air in the straw. because there is less air the pressure of the straw is reduced. but the atmospheric pressure on the surface of the liquid remains the same. henceforth how it helps you drink
How do atmospheric pressure zones and ocean currents affect earth's energy balance?
Warm temp create area of low atmospheric pressure on the Earth's surface while area of high pressure r generated when temp r relatively cold. Once established, the thermal gradient then develops a flow of air that goes from high 2 low pressure
How would gas exchange be affected at the top of a tall mountain where air pressure is lower and there is less oxygen then lower elevations?
At high altitudes, atmospheric pressure is lower. Therefore, the partial pressure (partial oxygen) is lower. As partial pressure of oxygen goes down, the body's desire for oxygen goes up.

What generally happens to atmospheric pressure on a windy day?
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
Does gravity go up or down?
Gravity is a force between 2 bodies. Gravity goes in the direction towards the body of greater mass. For things on earth, gravity is in the "downward" direction (i.e. towards the earth), since the earth is of greater mass than other objects.
Why do a weather balloon keep increasing in volume as it rises through the stratosphere?
As the weather balloon rises through the stratosphere, the atmospheric pressure decreases. This lower pressure causes the gas inside the balloon to expand, leading to an increase in volume. The gas molecules have more space to spread out due to the reduced external pressure.
Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
