Can upthrust be greater than weight?
YES...and examples are flying objects! Interestingly,Any liquid or gas produces upthrust. For example, the upthrust of air keeps a hot air balloon up.
What two forces act on the hot air balloon?
upthrust and gravity
Why does your cold water have water flow but hot water has no flow?
It is a matter of density cold water is denser(compact) that hot water. thus cold water will flow faster than less dense(loose)hot water.
What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
Why hot air balloons rises up in the sky?
Hot air has density less than the air surrounding the balloon. When the average density of the balloon filled with hot air is less than the density of the air outside upthrust is more than the weight of the balloon. therefore it keeps on rising up till the upthrust becomes equal to the weight of the balloon.
What size LP tank-less water heater is needed to reach 7gallons Per min.?
The size goes by how many gallons of hot water it will produce. So you get the one that says it will produce 7gpm.

What objects use upthrust?
many things use upthrust, some i can name are: a hot-air-balloon, a aeroplane a parachute and possibly a elevator.

How do cold air and hot water make the water freeze faster?
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze
Why does the body produce less urine in hot weather?
Our body produces less urine in hot weather due to a number of reasons which may include sweat,breathing and other bodily functions(like digestion).
What does hot water have that cold water does not have?
Hot water is less denser than cold water and has a greater temperature.
What does cold water have that hot water does not have?
Hot water is less denser than cold water and has a greater temperature.
Why does die spread quiker in hot water to cold water?
Because the hot water is less dense than the cold water, so the dye molecules have a better chance of making it through the less compact hot water.
Why a lot of hot water is pour onto skin will causes more painful compare to less hot water?
Because the water is hot!
