Why spirit is not used in thermometers?
Melting (freezing) point is −7.2 °C, boilingpoint is 58.8 °C; this temperatures are too close to each other. Besides Bromine is a toxic, easily evaporating liquid when spilled) Compare Mercury: Melting (freezing) point is −38.8 °C, boilingpoint is 356.7 °C and not easily evaporating liquid. (The liquid itself is very toxic, vaporous Hg is very toxic)
What is an example of high and low viscous material?
Viscosity is a measurement of how much a liquid resists flow or deformation -- viscous liquids tend to move more slowly than non-viscous liquids. An example of a highly viscous liquid might be honey or molasses; vinegar and water have low viscosity.
Describe the five states of matter?
There are currently 5 states of matter, namely solid, liquid, gas, plasma and Bose-Einstein condensates.Solids are basically objects, such as a rocks and humans. They have a definite volume and shape. They cannot be compressed as the molecules in a solid are very closely packed due to strong intermolecular forces that bonds the molecules together. They expand when heated and contract when cooled. When heated, the molecules vibrate the more and more vigorously in their places when the temperature increases.Liquids are water-like matter, such as seawater and paint. They have a definite volume, however have no definite shape, as the intermolecular forces are not as strong as those in solids to bond the molecules together. Hence, the molecules will move around the container when tilted to reach a horizontal level (plane). They can be compressed, however only to a small extent. They expand when cooled (ice in solid state) and contract when heated (water vapour in gaseous state). The molecules will then become compacted or move further apart when in the respective states. The molecules will lose energy when steam condenses to water.Gas is basically the air. The air is usually made up different kinds of gases, such as oxygen and carbon dioxide. However, they all share common characterisics. Gases do not have a definite volume and shape, thus able to fill up anything, such as the atmosphere. They can be compressed as the intermolecular forces are weak. The gas molecules are spaced far apart, and they move in a continuous and random motion. Their speed varies according to the temperature and the number of atoms. The higher the temperature or the less the atoms, the faster they move. They bounce away from any other molecules (gas, dust or smoke), thus have no fixed motion. This is called the Brownian Motion. Diffusion is greatly present, where the molecules will diffuse in the air till it reaches a state of equilibrium. Gas also expands greatly when heated and contracts greatly when cooled.Plasma is the superheated phase where electrons get torn from the atom (ionization). It is the rarest phase of matter on Earth although it is the most common in the universe. They can be natural (lightning and the Sun) or man-made (fluorescent light tubes).Examples of Bose-Einstein Condensates are superconductors and superfluids. These are materials that are cooled till they almost reach absolute zero (0 K, -273.15 ­°C). Superconductors are materials (solids) that have no resistance to the flow of electricity, such as superconducting metals, alloys and compounds (alloy of Niobium and Titanium). They are extremely cooled they can repel a magnetic field. Superfluids are liquid gas, as water would be frozen by then, that have strange behaviours. Liquid helium, for example, is cooled till it can actually "creep" on the walls of a smaller container placed inside a larger container to enter and then form its own horizontal level, unlike the previously-mentioned characteristic of liquids! Superfluids are also able to trap light and slow its moving speed down, which is a great breakthrough. This topic has, however, not much data and we are not able to talk much about it currently.Actually water is highly unusual in that it expands when cooled. It is much more common for liquids to contract when cooled. However water molecules have an electromagnetic dipole which means they can Hydrogen Bond to each other. Hydrogen bonds are longer than normal intermolecular forces so when they become relevant (when the water is freezing) the bonds hold the molecules away from each other, lowering the density of ice. Water is at it's densest at 4 degrees centigrade, at higher temperatures than that it expands like all other liquids.
What kind of energy will be stored in the arrow when it is fired?
The arrow has combustible material coated on certainrestrictedarea of the arrow. This materials in coated form has highest potentialenergydue to stronger cohesive forces. when thismaterialswith stronger cohesive forces catch fire the molecules or the particles of the coatedmaterialgain higherkineticenergyby weakening cohesive forces. thekineticenergyof the particles faces resistanceand thus the kineticenergyis noted as frictional forcesbecausethe flame which withhigherkineticenergymoves forward faces resistance and flame may not go to more and more distance from the arrow area. Thus the cohesive and frictional forces do operate in flame movement or it could be termed as Friccohesity is highly operative factor for converting potentialenergyinto the kineticenergyof thematerialsin flame phenomenon.
If you have thick and thin wire which will make a generator light up more?
its highly impossible its highly impossible
Why patrol evaporates at room temperature?
Patrol (also known as petroleum ether) evaporates at room temperature because it has a low boiling point. The molecules in patrol have weak intermolecular forces, which allows them to easily escape from the liquid phase and enter the gas phase at room temperature. This rapid evaporation is why patrol is highly volatile and can be dangerous if not handled properly.
What is the relationship between polarity and vapor pressure?
They are inversely related. The volatility of a liquid increases with decreasing vapor pressure, as it provides more reversible effect on liquid molecules, so less liquid molecules are able to escape. Conversely, the volatility of liquid increases with decreasing vapor pressure, as it provides less reversible effect on liquid molecules, allowing more to escape.
Does Iodine have a high or low vapor pressure?
By agreement, the very definition of 'volatile liquid' identifies a liquid which evaporates at Standard Temp/Pressure. The rate at which it evaporates is called its vapor pressure. High VP means it will evaporate rapidly at STP. Theoretically, any material, element or compound, in liquid form can be made to evaporate by increasing the temperature and reducing the pressure. Gas-deposition makes use of this theory to build industrial diamonds from hot, highly-pressurized carbon vapor.
Is benzene or ethyl ether highly volatile?
Ethyl alcohol is highly volatile as compare to benzene.
Is glucose highly volatile?
No. A highly volatile substance is one that easily turns into vapor at or near room temperature. Glucose is quite stable as a solid.
What is bromine's appearance?
It is a dark red liquid highly volatile and highly toxic.
Is ammonium hydroxide a non volatile liquid?
No, ammonium hydroxide is highly volatile and gives out ammonia gas.
Which is more volatile acetic acid or water?
Alcohols have strong hydrogen bonding between each other, which makes it harder to vaporize. Acetone,however, has only weak Van der Waal's forces(London forces). This makes acetone easier to evaporate.
What happens to a gas if its intermolecular space is reduced?
If the intermolecular space is reduced then it won't be able to move freely and it also won't be highly compressible
Why can't water dissolve oils and pure hydrocarbons?
It is entropically unfavourable because water cannot interact efficiently through intermolecular forces with these molecules to intermingle and are forced to form highly organized structures to solvate them, and highly organized structure are not favoured by thermodynamics (positive delta S).
Is ethylene combustible?
Yes, its extremely flammable. It is used as a fuel but I'd advise you not to burn it as it hurts. OWEE!
