What happens when you pull water up into the vertical tube then remove the tube from your mouth?

when you take the water up the vertical tube the water in the pressure tube moves closer to the stopper and when you cap it the water no longer moves. Once you cap the end and release the one in you mouth the water in the pressure tube does not move at all

What happens when you remove the pressure-release cap?

there will be no ait that escapes because it would have to get by the water that is in the pressure tube and that water or liquid is blocking the water from passing. If you remove the cap the water can move more freely in the tube. However no air pressure is escaping from the bottle.

What happened when you blew a little air into the bottle?

the pressure in the tube is moved a little. when you remove you mouth a little water comes back up the vertical tube.

because there was more pressure acting on the water in the pressure tube. no, the air column did not move back to its original position when my mount was removed.

the vertical tube had some water com back up the tube then return to the jug.

When you blow air into the water it increases pressure in the bottle which trys to get rid of it through the pressure tube which cause the water column to move. I did not know that the water was going to come back up ther vertical tube I did know that the water column would move though

Your estimate of the pressure difference due to a 1% change in pressure, the corresponding change in air column height, and the required change in air temperature:

I am having trouble here I don't know how I wouldn't convert then.. I think that I am having a dumb moment right here but I need help to more on from here

The question told you

'The pressure in the bottle is probably in the range from 103 kPa to 110 kPa, depending on your altitude above sea level and on how high you chose to make the water column. You are going to make a few estimates, using 100 kPa as the approximate round-number pressure in the bottle, and 300 K as the approximate round-number air temperature. Using these ball-park figures:'

This information should be used in answering the three questions. Remember what a Pa is, what the k means, and what a kPa is. Then start by using the pressure in your bottle, in kPa.

Your estimate of degrees of temperature change, amount of pressure change and change in vertical position of water column for 1% temperature change:

The temperature change corresponding to a 1 cm difference in water column height, and to a 1 mm change:

water column position (cm) vs. thermometer temperature (Celsius)

Trend of temperatures; estimates of maximum deviation of temperature based on both air column and alcohol thermometer.

Water column heights after pouring warm water over the bottle:

Response of the system to indirect thermal energy from your hands:

position of meniscus in horizontal tube vs. alcohol thermometer temperature at 30-second intervals

What happened to the position of the meniscus in the horizontal tube when you held your warm hands near the container?

Pressure change due to movement of water in horizonal tube, volume change due to 10 cm change in water position, percent change in air volume, change in temperature, difference if air started at 600 K:

Why weren't we concerned with changes in gas volume with the vertical tube?

Pressure change to raise water 6 cm, necessary temperature change in vicinity of 300 K, temperature change required to increase 3 L volume by .7 cm^3:

The effect of a 1 degree temperature increase on the water column in a vertical tube, in a horizontal tube, and the slope required to halve the preceding result:
