Is ice cube a solid gas or liquid?
solid with hydrogen bonds making it less dense than its liquid form
Which phase change does not involve changing a liquid into a gas?
The liquid to gas phase change is vaporizing; the reverse is condensing. The other phase changes are: - solid to liquid: melting - liquid to solid: freezing - solid to gas: sublimation - gas to solid: deposition
Will O2 solid float in O2 liquid?
No, solid O2 will not float on liquid O2 at all. There are several different phases of solid oxygen, depending on the conditions under which it is formed. But all of them are more dense than the liquid form, even near its freezing point (where it is most dense). None will come close to floating. Liquid oxygen has a density of about 1.141 grams/ml or so, and the solid forms have densities in the area of 1.4 grams/ml or so. Very few substances have a solid phase that floats on its liquid phase. Water is almost miraculous in this physical phenomenon. If ice did not float on water, earth's oceans would freeze solid within a few thousand years (or less).
When a solid is heated it will usually change to this phase?
When a solid is heated, it will usually change to the liquid phase. This process is known as melting.
Can a solid be more dense than a liquid?
Yes, a solid can be more dense than a liquid. Density is defined as mass per unit volume, so a solid with a higher mass per unit volume than a liquid will be more dense. An example is comparing ice (solid) to water (liquid), where ice is more dense than liquid water.
When sound travels in gas is it more dense or less dense?
The gas phase is less dense than the liquid or solid phase of a substance. Density is not a property of sound.
Would it be true to say that solidfication is from a liquid to gas?
False. Solidification when a substance that is in a liquid changes phase to a solid.
Is the solid outer core more dense than the liquid inner core?
This question is based on a false assumption that the outer core is solid and the inner core is liquid. This is incorrect. It is in fact the inner core that is solid (and so is the most dense) and the outer core which is liquid.
How do water's relative densities as a solid and a liquid differ from that od most other substances?
Ice floats. Most other substances are denser in the solid state.
Will a solid flow up?
This depends on how dense the solid is, and how dense the liquid is.
Is it true or false that solids can go directly into the gas phase without becoming a liquid first?
False. Solids cannot go directly into the gas phase without becoming a liquid first. This process is known as sublimation, where a solid turns into a gas without passing through the liquid phase.
Which cold solid is less dense than the liquid when it melts?
Ice is a solid less dense than the liquid
Why would a solid be heavier than a iiquid?
For all substances, except water, the solid phase is more dense than the liquid phase. So if you had equal volumes of the solid phase and liquid phase, the solid phase would have more mass. For example, the density of solid iron is 7.874g/cm3, and the density of liquid iron is 6.98g/cm3. NOTE: The 3 after cm is supposed to be a superscript, so that cm3 is supposed to be cubic centimeters, however, currently the subscripts and superscripts are not working.
What are the phase changes of matter?
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Is ice cube a solid gas or liquid?

Why solid and liquid have high densities while gas have low densities?
For most substances, the solid phase is more dense than the liquid and gas phases. The liquid phase is less dense than the solid phase but more dense than the gas phase, and the gas phase is less dense than either the solid or liquid phases. Water is an exception. Its solid phase (ice) is less dense than the liquid phase.
