Temperature

Correct, water boils at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure. At this temperature, the water molecules gain enough energy to overcome the intermolecular forces holding them together in the liquid state, resulting in the water transitioning into the gaseous state of steam.

A star with a temperature of 3000 degrees Celsius would appear red in color. This is because as the temperature of a star decreases, its color shifts towards the red end of the spectrum.

Yes, hail can form at temperatures below freezing, typically around -10 to -20 degrees Celsius. As water droplets are carried high into the atmosphere by updrafts, they freeze and can accumulate to form hailstones before falling to the ground.

Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum.

Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!

Temperature increase on a thermometer is typically indicated by the expansion of the liquid or mercury within the tube. As the temperature rises, the molecules in the liquid move faster, causing it to expand and rise up the scale on the thermometer. This expansion is calibrated to reflect the corresponding increase in temperature.

The dew point temperature is 21 degrees Celsius when the dry bulb temperature is 24 degrees Celsius and the wet bulb temperature is 22 degrees Celsius.

the higher self ignition temperature of the petrol is due to the low density than the diesel.

as

density = pressure / (R* temperature)

R= universal gas constant.

ex. hydrogen (gas) has density = .082 at 300 k

while kerosene has =810

(both are in kg/m^3)

and auto ignition temperatures are

hydrogen =500

kreosene=295

similarly , petrol-density=737

diesel has=820 to 950 .

5°C is considered cold. It falls within the range of temperatures typically associated with cooler, more moderate weather.

-65 degree Celsius = -85 degree Fahrenheit

302 degrees Celsius = 575.6 degrees Fahrenheit

Coke has a higher boiling point than Mountain Dew because it has a higher concentration of dissolved substances, such as sugar and caramel coloring, which increases its boiling point. Mountain Dew, on the other hand, has a lower concentration of dissolved substances, which results in a lower boiling point.

The temperature on a rainy day can vary widely depending on factors such as location, season, and weather patterns. In general, rainy days tend to be cooler as the rain can lower the temperature, but it is always best to check the local weather forecast for the most accurate information.

No, 0 degrees Celsius does not kill bacteria. It can slow down their growth and reproduction, but many bacteria are capable of surviving freezing temperatures and can remain dormant until conditions are more favorable for growth.

There are 180 divisions between the freezing point (32°F) and the boiling point (212°F) of water on the Fahrenheit scale.

1.3 kg water = 1300 grams.

q(Joules-heat energy) = mass * specific heat * change in temperature

q = (1300 g)(4.180 J/gC)(100 C - 20 C)

= 4.3 X 105 Joules of heat energy

As altitude increases, the air pressure decreases. This results in lower boiling points for water because there is less atmospheric pressure pushing down on the water. However, the freezing point of water is not significantly affected by altitude.

7.9 degrees Celsius = 46.22 degrees Fahrenheit

Amsterdam typically has around 160 days of sunshine per year.

I'm not sure, although I believe it is somewhere around 50,000,000 degrees. The sun is so hot, that before you even got to it, you'd burn up. But without the sun to keep us warm, we wouldn't survive in the cold.

The surface temperature is about 5,500 degrees C. However it gets much hotter, millions of degrees, towards the core, as it must for nuclear fusion to take place.

25th November 1989 was a Saturday.

28 degrees Celsius = 82.4 degrees Fahrenheit

4400 degrees Celsius is equal to 7982 degrees Fahrenheit. This conversion can be done using the formula: (Celsius temperature x 9/5) + 32 = Fahrenheit temperature.
