Answer 1

Without introducing a 3rd substance, there are only 2 methods to accomplish what you're asking.

1/ increase the density of the substance you want to submerge, but without knowing the physical properties it's impossible to propose anything

2/ decrease the density of the water:

put whatever you want to submerge in a pressure vessel and pour in water. make sure that the combined volume of the water and the substance is less than one or two percent of the total volume of the vessel. place the lid on and heat until the temperature reaches 120 to 130 degrees C. your substance is now submerged in water.

You'll want your teacher to assist to prevent an explosion.

Answer 2

freeze the substance that is less dense than water. It will sink because the atoms making up the substance are bunched together tighter than the equillibrium of the more dense water (at room temperature).

Answer 3

I've got a couple ideas:

-Tie a rock to it.

-push down on it with a stick

As long as the supstance is less dense than the liquid it is in, the substance will float.

Answer 4

Attach it to a substance that is more dense than water (cement boots on your feet) or change the density of the water.

Answer 5

maximum regularly availible components that are much less dense than water is oil, alcohol and plastic. in certainty, extremely some organic and organic solvents which includes acetone, methanol and methylene chloride are additionally much less dense than water. to boot, extremely some categories of polymer are "lighter" than water, too.

Answer 6

Put air inside the material. Like volcanoes do with stone, making pumice stone.

Answer 7

add material that is more dense than water ie most metals.

Answer 8

Try and make it float in air.

Answer 9

Sit on it.

Answer 10

please explain more. what are the conditions of the problem?
