The solid cannot float in this liquid.
The process is called 'dissolving', provided the solid substance is soluble in the liquid solvent in which it is present.
They freeze. Liquid hydrogen is very cold.
I assume you mean a solid that has the same density as a liquid that it is submerged in. If they have the same density, then when the solid is in the liquid, there is exactly zero net force acting on it (weight of solid object is perfectly balanced by bouyant force), so the solid object will just "sit there," assuming there are no other outside forces acting on it (ex. currents, etc.). If the object is dropped into the liquid, for example, it will move deeper into the liquid (because it has downward momentum from the drop) until resistance from the liquid stops its motion, at which point it should remain stationary.
the liquid in the thermometer rises because of the surrounding heat which causes a chemical reaction wihtin the substance which makes the liquid rises. When, the liquid sinks, itn is because the air has gotten cooler
Gas molecules are spread out. When they are placed under pressure they condense into a liquid.
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. also an object will sink if it is denser than the liquid it is placed in.
An object will float if it has less density than the liquid in which it is placed.
an object will float on a denser liquid
An object with lower density than the liquid will float, one with more density will sink. Anything with the same density will stay at the depth where it is placed. If it is placed half submerged it would sink until submerged.
A number of factors have to be considered, the state of the substance, solid, gas or liquid. The condensation and freezing point of the substance. The temperature inside the freezer. The pressure Most, but not all, substances reduce in volume and increase in density when cooled. Water for instance, reduces in density when frozen.
An object with greater density than the liquid it is placed will tend to sink
An object will sink if its density is greater than the liquid in which it is placed; it will float if its density is less.
Yea
It isn't clear what units you are using, what liquid you are placing it in, and whether that is the density of the object or of the liquid. The general rule is that an object will float if it has less density than the liquid in which it is placed.
The process is called 'dissolving', provided the solid substance is soluble in the liquid solvent in which it is present.
It floats
Only objects having a density higher than the density of a liquid sink.
