To make air lighter you would increase the heat inside the balloon, making it less dense, causing it to rise.
No, because vacuums only take out the air. The clothes are still affected by gravity and have the same mass. Matter can neither be created nor destroyed. The only change is the density due to removed air which can make the items heavier per volume
put a hole in a box to make it lighter:)
no it weighs things down . Hot air tends to lift things, as in a hot air balloon.
Make the "something" lighter when going agaiinst gravity (up).Make something heavier when going down.Make the force acting on the "something" biggerMake the "something" move easier through or on whatever it is moving through or on. Make it more aerodynamic, make any wheels spin easier etc etc.
I think it would be lighter because all the moisture has gone from the substacne which would make it lighter.
No. It will make it lighter because there is less material.
because you
A heavier snake would, though lighter would not.
Heat them up with a lighter or other heat source.
Most fruit is heavier in water and will sink. Lighter fruits such as cherries and citrus slices will float. To make them sink, they could be frozen to make them heavier. They will eventually become waterlogged and sink.
This question doesn't make sense ... are you a six year old?
you make it so it is heavy but with a light top and evenly balanced make it heavier, and as you go up, lighter
trick question you cant put anything in a bag to make it lighter. every thing has mass, and mass includes weight. therefor by putting anything into a bag it would make the bag heavier.
Yes, diesel will float on top of water. This is because the petrol will weigh less than the water will weigh, therefore it will float on top of the heavier substance.
You must let the lighter one go first then let the heavier one go. The heavier should then catch up.
Fire makes things rise as it is a very strong source of heat. So does hot air. Fire causes hot air and because hot air is lighter than cold air, it rises. Is that good? (my first answer X3)
