Liquid

Volatile liquids require a small amount of thermal energy to vaporize due to the fact that many contain nonpolar molecules. This property of volatile liquids was utilized in this experiment to determine the molar masses of unknown volatile liquids by employing the ideal gas law in the course of vaporization and condensation of the liquids. This was done by taking measurements of volume, temperature, mass, and pressure throughout various steps of the experiement. These findings were then applied…

It shows that in the solid-liquid extraction, most of the…

This experiment was conducted to practice a variety of techniques in organic chemistry: separation, mechanisms, acid-base reactions, evaporation, recrystallization, and identification. The goal of this experiment was to identify the unknown mixture of two compounds. The two compounds were separated first by altering the acid components solubility through deprotonation, and then protonating the acid component again to form the separated precipitate. The ether in the neutral layer was evaporated,…

Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…

Many have asked the question why doesn't Mars have oceans? A recent breakthrough discovery has confirmed that liquid water does exist on Mars. This means there is the potential for life to exist here. However, this water is very minimal compared to previous levels of water found on Mars. A study done by Geronimo Villanueva and Michael Mumma of NASA’s Goddard Space Flight Center reveals that Mars used to have at minimum seven times as much water as it does today with there being enough water to…

Liquid life In the novel, water is so common, so expected, we forget it was there altogether. At sea, there is a boat, a lion and a boy, but no water. However, Pi understands the necessity of water. Being deprived of it, he calls it “liquid life” when it touches his lips, quenching his thirst. Water isn’t just life blood in the book, it’s a messenger and a barrier PI must overcome to survive. Most obviously, you need water to live. After days without water and incredibly weak, PI gets a taste…

IONIC LIQUIDS Introduction:- Ionic liquids are actually salts that are liquid in state, normally referred to compounds that have melting point below an arbitrary temperature i.e. 100° C. Unlike some other ordinary liquids like water and gasoline, that are composed of neutral species while ionic liquids are composed of ionic species and ionic intermediates commonly known as “ionic fluids” and “liquid electrolytes”. In ionic liquids there is a species that has a delocalized species and the other…

Subject: Science Concept: Solid, liquid, or gas Sunshine State Standards/Access Points/Common Core: SC.2.P.8.2- Identify objects as solid, liquid, or gas. Primary Instructional Objectives: - Students will be able to identify what the difference is between a solid, liquid, and gas. - Students will be able to identify examples of solids, liquids, and gasses. - Students will be able to sort objects by whether they are solid, liquid, or gas. - Students will be able to define matter and where you…

Candy Waterfall: Can Solids Flow Like Liquids? Introduction Does the shape and size of candy affect how it flows? What do candy, sand, and cereal have in common? They are both granular materials. Engineers need to know exactly how fast materials flow down a funnel so they can get the right amount in each box. Imagine if you had a box of candy and you opened it and it is only halfway full, wouldn’t you be mad? That is why factories and engineers need to work together to find out how fast…

Cost of a liquid cooling system Liquid cooling systems prices start from around $300 and go over the price range of $1000 for this system, which makes it much more expensive than traditional cooling systems which go around the price range of $40 - $100. You also need to do maintenance on a liquid cooling system which this maintenance is also expensive and takes a lot of time, where in a traditional cooling system you only replace it once every four years to make sure everything is working…
