Temperature

Changing water pressure can affect the boiling point because it alters the equilibrium between liquid and vapor phases. Increasing pressure raises the boiling point, as more energy is needed to overcome the higher pressure. Decreasing pressure lowers the boiling point, as it requires less energy to vaporize the liquid.

The temperature in the troposphere can vary depending on factors such as altitude and location, but on average it decreases by about 6.5 degrees Celsius per kilometer of altitude. Near the Earth's surface, the average temperature of the troposphere is around 15 degrees Celsius.

38.8 degrees Celsius = 101.84 degrees Fahrenheit

[°F] = [°C] × 1.8 + 32

250g of water at 10C needs to lose 1 cal/g/C or 2500 calories to drop temperature to zero.

The latent heat of fusion of water is 80 calories per gram at 0C so, the water needs to lose 20,000 calories to turn to ice at 0C

Finally, the ice needs to lose 0.316 cal/g/C or 790 calories to drop to -10C

The total heat released is then 2500 + 20,000 + 790 = 23,290 calories

The average temperature on Mars is about 210 Kelvin (-63 degrees Celsius or -81 degrees Fahrenheit). However, temperatures can vary greatly depending on the location and time of day on the planet.

The average surface temperature on Mercury is around 700 K (426.85°C). However, temperatures can vary greatly depending on the location and time of day due to Mercury's lack of atmosphere to regulate heat.

It depends of the pressure, but at normal pressure, 1.01325 Pa, the water freezes at 0°C.

The universe was hotter in the past due to the Big Bang event which marked the beginning of the universe. As it expanded and cooled over time, galaxies, stars, and planets formed.

At higher altitudes, the air becomes less dense, leading to a decrease in temperature due to lower pressure and reduced heat retention from the Earth's surface. The temperature can drop as much as 3.5°F for every 1,000 feet of elevation gain, leading to the extreme cold temperatures experienced at higher altitudes.

74 degrees Celsius is equivalent to 165.2 degrees Fahrenheit.

A star's temperature is indicated by its color, with hotter stars appearing blue and cooler stars appearing red. Brightness is measured using the star's apparent magnitude, with higher magnitudes representing dimmer stars and lower magnitudes representing brighter stars.

The surface temperature of Vega, a star in the constellation of Lyra, is estimated to be around 9,600 degrees Celsius.

The coldest temperature recorded in Wales was -23.3°C (-9.9°F) in Rhayader, Powys on January 21, 1940.

The temperature of Cygni, or specifically the star Deneb (also known as Alpha Cygni), is estimated to be around 8,500 Kelvin. This makes it a very hot and luminous star compared to our Sun, which has a surface temperature of about 5,500 Kelvin.

You would say there is a different temperature range everyday.

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.
