When the air in a balloon is heated what happens to the density?
it becomes low
When air is heated it rises this is because?
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
What does density have to do with convection?
Things with a lower density will float on things with a higher density. If you take a fluid (air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated. Get it? Hope you do!
How do you estimate the mass of air if the density of air is 1.3kg per m3?
You multiply the volume of the desired object - the inside of your room, perhaps - by the density.
What are two major characteristics that change when air is heated and cooled?
It depends on how high you heat or cool the air. The density and entropy as functions of temprature would be affected mostly. By heating the air density decreases and entropy increases.
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
When air is heated and fewer gases are in it the air weighs and the air pressure?
it weighs 14.7 pounds
When air is heated and fewer gases are in it the air weighs and pressure?
it weighs 14.7 pounds
When air is heated and fewer gases are in it the air weighs and the pressure?
it weighs 14.7 pounds
When the air in a balloon is heated what happens to the density?
it becomes low
What happens to the density when heat is added?
The density of air when it is heated decreases
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
What will happen to air if it is heated along a slope element?
Generally, if air is heated, its temperature will increase. And if the pressure remains constant, its density will decrease.
When air is heated it rises this is because?
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
When air is heated its volume increases it's mass stays the same and the density of the air does what?
yes
When air is heated its volume increases it's mass stays the same and the density of the air what?
yes
When air is heated and fewer gases are in the air weighs?
ask your mom and if she doesnt know i dont know what to tell you
