Why upthrust force is higher in hot water than cold water?
Hot water is less dense than cold water because the increased temperature causes the water molecules to expand and spread out. As a result, the same volume of hot water displaces a larger mass of surrounding water, creating a stronger upthrust force due to the greater difference in density.
Can upthrust be greater than weight?
Yes, upthrust can be greater than weight in fluids with high densities, such as water. This can result in objects floating or being pushed upwards in the fluid.
What are the practical uses of upthrust?
Upthrust can be used in designing flotation devices, such as life jackets and boats, to keep them afloat on water. It is also utilized in hot air balloons to provide lift and enable them to float in the air. Understanding upthrust is crucial in engineering and designing objects that need to float or hover.
Applications of upthrust in real life?
Upthrust, also known as buoyant force, is applied in various real-life scenarios such as designing ships and submarines to ensure they float and control their buoyancy. It is also important in swimming and diving as it helps objects and people to float or sink in water. Additionally, upthrust is utilized in hot air balloons to help them fly by providing lift.
What two forces act on the hot air balloon?
Two forces that act on a hot air balloon are lift, generated by the heated air inside the balloon being less dense than the surrounding air, and gravity, which pulls the balloon downward.

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.

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 cold water have that hot water does not have?
Hot water is less denser than cold water and has a greater temperature.
What does hot water have that cold water does not have?
Hot water is less denser than cold water and has a greater temperature.
Why a lot of hot water is pour onto skin will causes more painful compare to less hot water?
Because the water is hot!
