What is natural draft in a boiler?
when the weight of warm air in the stack is less than the cool air around the stack , it causes an upward flow pulling air thru the furnace
The weight of the air on the earths surface is?
The weight of the air on the earth is called... Air Pressure
Why do beaker need to cool before weighing?
A hot beaker warms the air around it, which causes it to rise. For very sensitive balances, the updraft produced can reduce the measured weight.
How did Galileo estimate the weight of air?
Galileo developed an experimental apparatus called the "weighing astration" to estimate the weight of air. In this device, he balanced a sealed container filled with air against an equal weight of water. He observed that the container became lighter when air was removed, leading him to conclude that air has weight.
Are air is weightless?
Air has weight because it is made up of molecules of matter and all matter has weight and mass.
What if your weight equals your?
When your weight equals ur mass it causes friction in the air
What causes barometric pressure?
Barometric pressure measures the weight of the air.
What causes air pressure in the air?
It is the weight of the air itself that causes air pressure. Fluctuations occur due to changes in wind and temperature. We live in air pressure of about 15 pounds per square inch.
What is the force you exert on an airplane as it is flying in the air?
Weight. Also, the moving air around the plane causes friction
Gravity causes water other fluids and air to have weight and thus to exert pressure?
Yes.
What causes the air pressure drop as you travel upward from earth's surface?
Pressure is the weight of air column on unit area. As you go upward, this air column gets shorter, its weight gets less, hence air pressure gets lower.

What is draft in boiler?
when the weight of warm air in the stack is less than the cool air around the stack , it causes an upward flow pulling air thru the furnace
What is the result of the weight of a column of air pushing on an area?
You might have expected the result to be pressure, but it's not. Pressure occurs due to the bombardment of air molecules on a surface. The weight of a column of air causes so little pressure that it can be considered negligible.

What is the result of weight of a column of air pushing down on a area?
You might have expected the result to be pressure, but it's not. Pressure occurs due to the bombardment of air molecules on a surface. The weight of a column of air causes so little pressure that it can be considered negligible.
