If both layers are water, then make one of them warmer than the other one.
The best way would be to change the state of the water. In other words, have ice floating in liquid water, while steam is above that.
Liquids can float on each other due to differences in their densities. When a less dense liquid is poured on top of a denser liquid, it will float because it is lighter and less likely to sink. This is known as stratification, where liquids of different densities form layers with the least dense liquid on top.
Ice can float on liquid water.
Ice can float on liquid water.
No, although it is lighter than diesel and therefore would normally float to the top, the two will dissolve in each other forming a new liquid that will not separate into layers.
The oil will float above the water, as they wont mix with each other, and oil is lighter.
the density of oil is more than the water.so,they will never dissolve with each other, rather the oil will float over the water.
A pin can float on water due to surface tension. Water molecules at the surface are more attracted to each other than to the air above, allowing the pin to sit on top of the water without sinking. This surface tension supports the weight of the pin, enabling it to float.
Because they aren't soluble in each other and have different densities.
1- why should alternate layers be laid at 90 degrees to each other?
wet ice causes ice layers to slide over each other
3 liquids- oil, water, and cleaning stuff can float on top of each other 3 solids- foil, paper, rocks
