Pronunciation: [sˈʌb lˈa͡ɪmz] (IPA) 
The phrase "sub limes" is often misspelled as "sublime" due to its similar sound. However, "sub limes" consists of two separate words – "sub," meaning under or below, and "limes," meaning a boundary or limit. The pronunciation of "sub limes" is /sʌb ˈlaɪmz/ with the stress on the second syllable of "limes." It is important to pay attention to the correct spelling and pronunciation of words to avoid confusion and misinterpretation.
"Sublimes" is a term used primarily in chemistry and physics to refer to a specific process known as sublimation. Sublimation is the transformation of a solid substance directly into its gaseous state, bypassing the liquid phase entirely. The word "sublimes" is the present tense of the verb "sublime" in the third person singular form.
In the context of sublimation, when a substance sublimes, it undergoes a phase change caused by the application of heat or reduction in pressure. This process allows solids to transition directly into a gas without first melting into a liquid. As a result, the substance appears to evaporate or vaporize instantly.
Sublimation has various practical applications. It is used, for instance, in freeze-drying processes to remove moisture from perishable goods while preserving their structure. Additionally, certain substances, such as dry ice (solid carbon dioxide), sublime directly at room temperature and atmospheric pressure, creating a visually striking effect. This phenomenon is often observed when dry ice is exposed to air, causing it to convert into a gas, bypassing the liquid state.
In summary, "sublimes" is the present tense of "sublime" used to describe the process of sublimation, wherein a solid substance transitions directly into a gaseous state without first becoming a liquid.
