Sublimation is, in fact, a universal phenomenon exhibited by all solids at temperatures below their triple points. However, sublimation is a scientifically and technically useful phenomenon only when the vapor pressure of the solid phase is high enough for the rate of vaporization to be rapid. Four of such solids include iodine, sulphur, naphthalene, and even dry ice (solid carbon dioxide).
What else can I help you with?
Sublimation is the process of turning a liquid into a gas?
No. So, you haven't had company for a while, and when they arrive you haven't any ice, although all 3 ice trays were full just a few weeks ago! Sublimation occurs when a solid transpires directly into a gas.
What safety precautions should be taken when using radioactive substances?
you need to stay about 3-4 feet away from the substance.
What are four types of mixtures?
Mixtures are substances that are made by physical combination of one or more substances and none of the constituent elements are changed. The basic classification of mixtures is into homogeneous and heterogeneous substances. They can also be further divided under these two categories in to solutions, dispersions or colloids.Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution. Heterogeneous mixtures include fine sand or silt in water.Rate This Answer
What are 4 substances Stanley Miller put in his apparatus for his 'primordial soup' experiment?
hydrocyanic acid, formic acid, acetic acid, lactic acid
Does water has a fixed volume?
No, it does not. The volume of water changes according with it's temperature. Water, unlike other substances, it has a minimum volume at 4 degrees Celsius.
What is the name of the process due to which dry ice changes into carbon dioxide gas?
The answer should be sublimation but if given 4 multiple choice and it is not there, it might be fusion. If neither of those, you're screwed.
What are the 4 requirements for sublimation?
The four requirements for sublimation are: a solid substance must have a high vapor pressure at a certain temperature, the pressure of the substance in the environment must be lower than its vapor pressure, the substance must be able to undergo a phase change directly from solid to gas without passing through the liquid phase, and there must be sufficient energy for the solid particles to break free and transition to the gas phase.
What are 4 physical changes that radium can go through?
Radium can undergo several physical changes, including solidification, where it transitions from a gaseous or liquid state to a solid form. It can also experience melting when heated above its melting point, changing from solid to liquid. Additionally, radium can undergo sublimation, directly transitioning from solid to gas without becoming liquid at certain conditions. Lastly, radium may undergo thermal expansion, where its volume increases as it is heated, affecting its physical dimensions.
How is energy stored in substances?
Energy can be stored in substances through chemical bonds, such as in the form of potential energy. When substances undergo chemical reactions, these bonds can be broken or formed, releasing or absorbing energy. Additionally, energy can be stored in substances in the form of kinetic energy, such as in the movement of particles within a substance.

What is a 4 letter word that what cells can undergo meiosis?
The four-letter word you're looking for is "gamete." Gametes are the reproductive cells, such as sperm and eggs, that undergo meiosis to produce genetically diverse cells for sexual reproduction.
What are the six changes in state?
The six changes in state 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).
Substances that needs help to get into a cell?
some of the substances that need help to get into a cell would be carbohydrates, such as glucose and fructose, charged ions (H+, C-4), or substances moving against a concentration gradient. those are the main ones but not necissarily all of them.
