Temperature

Actual temperature reflects actual temperature. Wind chill is an attempt to quantify the effective lowering of the air temperature caused by the wind affecting the rate of heat loss from an exposed person.

The temperature at the equator can vary depending on the time of year and specific location, but it generally ranges from 25 to 35 degrees Celsius (77 to 95 degrees Fahrenheit). The equatorial region typically experiences warm temperatures year-round due to its proximity to the sun.

Yes actually, A cup of boiling hot water thrown into very cold air (for example, at −37°C, or −35°F, as shown in the photograph) will almost instantly freeze in midair and create a shower of tiny ice crystals. There are several reasons behind this phenomenon. First, the near-boiling water is already close to becoming steam when it is thrown into the air, which means that the water molecules are much closer to evaporating into the vapor state than they would be if the water were cold. Second, the act of throwing the water into the air causes it to break up into tiny droplets. The water that was contained in the cup (which originally had a relatively small surface exposed to the air) now experiences a tremendous increase in the total surface area exposed to the air. This situation helps to speed up the evaporation process (evaporation is the process of turning from a liquid to a vapor). Finally, very cold air typically has a low humidity level (that is, a low amount of water vapor present). This is yet another factor aiding the transition from liquid water, to water vapor, to ice crystals. At sufficiently low temperatures, this process seems to occur almost instantaneously.

I saw a tv documentary in which the host went to the coldest town in Siberia- and he stated that his LCD thermometer couldn't tell him what temperature it was because LCD screens freeze at -20 degrees Celsius

At sea level, water freezes at 32 F and 0 C.

With the microwaved water, it pretty much depends on the microwave Owens temperature.

Though boiling water is 100 degrees Celsius.

(I would like to add): The water's temperature depends how long the microwave runs and the power of the microwave. However, if the water is boiling in the microwave, it is the EXACT same temperature as water boiling on the stove. The microwave is just another method of boiling the water.

the freezing point is always the same as the melting point therefore the answer is 3823 K (3550°C or 6422°F) there is no way in hell they cud b the same cuz the melting point is 3550c

Temperature is an important factor, but temperature alone cannot predict that ice will melt. Adding the heat of fusion to ice at zero degrees centigrade will cause it to melt without elevating its temperature, and removing the heat of fusion from water at zero degrees centigrade will cause it to freeze without lowering its temperature.

The freezing point of water is 0 degrees Celsius and 273.15 Kelvin, while the boiling point of water is 100 degrees Celsius and 373.15 Kelvin. This means that the difference between freezing and boiling points is 100 degrees Celsius or 100 kelvins.

Freezing water in Celsius helps to preserve it by keeping it at a low temperature, which slows down bacterial growth and helps maintain its quality. It also allows for long-term storage of water without it spoiling or becoming contaminated.

Temperature affects gas by changing how much energy each particle has. The hotter gas is the faster each particle moves around, therefore the colder gas is the slower the particles move. If the gas gets cold enough if will turn into a liquid and if it gets even more cold it will turn into a soild.

All tempertures, it just evaporates faster as temperature rises until it boils @ 212 and it evaporates the fastest. It even evaportes when frozen. Under atmospheric pressure, water evaporates at 100 o C (or 132 o F). However, the higher the water pressure, the higher its boiling temperature (or the temperature at which water evaporates).

The freezing point of propane is approximately -188.2 degrees Celsius.

Iron melts at 1535 °C

or

2797 °F for those you us living in the U.S..

this is not a thing that melts easily

Yes, salt lowers the freezing point of water by disrupting the hydrogen bonding between water molecules, making it harder for them to form solid ice crystals. This is why salt is commonly used to melt ice on roads and sidewalks during winter.

Zero degrees Celsius. The Celsius temperature scale was defined with zero as the freezing point of water, and 100 as the boiling point of water.

(That's for pure fresh water at sea-level atmospheric pressure. Adding impurities to the water will change the freezing and boiling temperatures, and different air pressures will change the boiling temperature of water.)

n-butyl alcohol has a higher boiling point than di-ethyl ether because there is more hydrogen bonding in n-butyl alcohol which results in a higher energy needed to break the intermolecular hydrogen bonds.

Pure water freezes at 0 degrees Celsius. When other things are put into solution in water, it normally causes the temperature of freezing to lower. Salt is capable of causing ice to melt because the it lowers the freezing point of any water (including ice) with which it is in contact, and that is why it is used on icy roads.

So the short answer is, when there is salt or sugar in water, you have to remove more heat to freeze it, and so it takes longer.

Melting point trends on the periodic table can be understood in a crude way using the following rule of thumb: The stronger the forces that act between molecules of a substance, the higher the melting point tends to be.

The trends are very complex because many different factors influence the forces between atoms (or molecules) in an element. Notice that for each period beyond the first, the melting point rises to a maximum somewhere around the middle of the period and then falls off to a minimum value at the end of the period.

The melting points of the first period elements are extremely low, because forces between H2 molecules and between helium atoms are exceptionally weak.

In the second period, there is a gradual transition from relatively weak metallic bonding in lithium to strong network covalent bonding in carbon. Nitrogen, oxygen, and fluorine also form strong covalent bonds but they can't form networks of bonds the way carbon does. Atoms of these elements pair up to form diatomic molecules. While the attractive forces within atoms in the diatomic gas molecules is strong, the forces between molecules is very weak. That causes the sharp dropoff in melting point after carbon in the second period.

The trend is repeated in a more subdued way in the third period. There is a jump in melting point from aluminum to silicon where bonding changes from primarily metallic to more covalent. P and S are better able to link into chains and rings than their second period counterparts, and have much higher melting points than N2 and O2. In the fourth period, the rise and fall of melting points across the period is even more muted. Note the discontinuity going from gallium (Ga) to germanium (Ge) at the metal/metalloid border.

0 degrees celsius is the freezing point of water.

Room temperature depends on whatever temperature the room happens to be, but the generally accepted temperature for "room temperature" is roughly 70ºF, or about 21ºC.

To calculate Celsius from Fahrenheit you subtract 32 from the degrees Fahrenheit, multiply this number by 5, and then divide that number by 9.
