The average temperture of Mars?

The average temperature on Mars is around -80 degrees Fahrenheit (-60 degrees Celsius). However, temperatures can vary widely, with lows reaching -195 degrees Fahrenheit (-125 degrees Celsius) at the poles and highs around 70 degrees Fahrenheit (20 degrees Celsius) near the equator during the day.

Who was Gabriel Fahrenheit?

Daniel Gabriel Fahrenheit (born May 24, 1686 in Danzig; died September 16, 1736 in Den Haag) was a Dutch-German-Polish physicist, engineer and glass-blower who invented the mercury thermometer in 1714.

Fahrenheit is most widely recognized today as the developer of the temperature scale which bears his name.

What state is water at -20 degrees celsius?

At -20 degrees Celsius, water is in a solid state and is frozen as ice.

Is it possible for water to freeze due to radiative cooling when exposed to the black body cloudless night sky even if the ambient air temperature is above freezing?

The short answer is yes. Ever slip on ice when you know the temperature wasn't below freezing?

The air temperature is directly controlled by the amount of infrared radiated away from a surface, blackbody or not. Technically, air temperature is defined as the temperature at 2 meters, so you have to mix the air between 2 meters and right at the surface. So that's where your question comes in - if mechanisms of conduction and convection can't efficiently mix that loss of heat from the surface, then yes, this scenario would play out. Practically, it would have to be only a couple degrees above freezing though.

Note: I have actually observed this. An important condition is very still air so that there is no wind to aid convective warming of the water. It also helps if the air is very dry so that evaporation is encouraged - to add to the cooling of the water. (And, as previously mentioned, it is also necessary to have it close to freezing temperature.)

Does mars have a temperature of 180 degrees celsius?

No, Mars does not have a temperature of 180 degrees Celsius. Average temperatures on Mars can range from about -80 degrees Celsius at the poles to around 20 degrees Celsius at the equator during the day.

What happens to bacteria at 63 degree celsius?

Bacteria in food reaching a temperature of no more than 63c is very dangerous. Bacteria thrive at this temperature. Food is in what can be referred to as a 'high risk or danger zones'. Food should not be consumed and should be destroyed.

How many degrees celsius is 14 Fahrenheit?

Celsius to Fahrenheit is worked out by using the formula:

C = (F - 32) x 5/9

and Fahrenheit to Celsius is worked out by using the formula:

F = C x 9/5 + 32.

So, 14oF = (14 - 32) x 5/9 = -18 x 5/9 = -10.

So, 14oF = -10oC.

What is the convert of 302 degrees Fahrenheit to celsius?

To convert 302 degrees Fahrenheit to Celsius, subtract 32 from 302 and then multiply the result by 5/9.

((302 - 32) * 5/9) ≈ 150 degrees Celsius.

Do nonmetals have higher melting points or lower boiling points?

Nonmetals typically have lower melting points and boiling points compared to metals. This is due to nonmetals having weaker intermolecular forces, such as van der Waals forces, compared to the strong metallic bonds found in metals.

The minimum temperature usually occurs near sunrise because?

http://www.islandnet.com/~see/weather/elements/dawncold.htmmost places are at the minimum temperature shortly after sunrise but within an hour after of sunrise. The reason for this is that when the sun angle is low, the energy still being lost to space (long wave or IR radiation) exceeds the amount that is being received during that first half hour or so after sunrise. The low sun angle means that the energy per unit area is low (the sunlight is spread over a larger area.) and the amount that is lost to the atmosphere due to the much larger distance the energy is traveling through the atmosphere at the low angle. Thus, the temperature continues to cool until the energy received from the sun, exceeds the amount being lost. which is not until the period of 1/2 to one hour after sunrise. http://answers.yahoo.com/question/index?qid=20081224103509AAB3YA9

Why does the temperature drop when the sun rises?

The temperature typically drops when the sun rises because during the night, heat radiates out into space causing the surroundings to cool down. Once the sun rises, it begins to warm up the Earth's surface and the surrounding air, leading to an increase in temperature.

How do you convert C temp to F temp?

To convert Celsius to Fahrenheit, use the formula: F = (C x 9/5) + 32. Multiply the Celsius temperature by 9/5, then add 32 to get the equivalent temperature in Fahrenheit.

In cell isolation why must cold buffer and centrifugation be carried in cold temperatures?

Keeping the buffer and centrifugation cold helps to maintain cell viability by slowing down cellular processes that can lead to cell death. Cold temperatures also help to prevent protein degradation and maintain cell integrity during the isolation process.

If one pound of water is at a temperature of 32 degrees Fahrenheit, how many BTU’s must be removed in order to create a block of ice at 17 degrees?

LATENT HEAT OF FUSION

When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.

What is the state of sodium at 1000 degrees Celsius?

It depends on what temperature scale you are using.

For Celsius (ºC), Sodium is has already melted and will be in liquid form.

For Fahrenheit (ºF), Sodium has not yet melted and is in solid form.

What substance in the upper atmosphere is important to temperature changes in the upper atmosphere layers?

it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.

Is 64 cold,hot or worm?

64 is considered warm. It is not cold or hot.

Would you rather drink a cold milkshake in the cold or drink hot chacolate in the hot?

Well in my opinion, I would drink a hot chocolate in hot areas because you won't really be feeling much heat if it's hot since you don't want to drink something in one go otherwise it will burn so the hot chocolate will turn cold soon anyway.

What is data logger?

Temperature is measured with thermometers that may be calibrated to a variety of temperature scales
