# Is 47 degrees Celsius fever?

Body temperature between 37-39°C is considered a mild fever. Anything from 39-42 is high fever and above 42.4°C the fever is very dangerous and can cause serious, long-lasting damage.

## Is C below freezing?

Freezing or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface.

## What is twice as cold as zero?

So, if you are measuring in kelvins, twice as cold is not possible. (0/2=0) However, if you are using the Celsius scale, zero degrees is actually 273.15 degrees above absolute zero. So, twice as cold would be -136.575 degrees Celsius. Thus, from zero degrees F, twice as cold would be -229.835 degrees F.

## Which is colder Celsius or Fahrenheit?

Here is the answer, without further ado: neither. Neither of them is colder: -40° Fahrenheit is exactly equal to -40° Celsius!

## What is the temperature of a COVID patient?

Infants: rectal temperature of 100.4°F (38°C) or higher. Toddlers and children: temperature over 102.2°F (39°C). Adults: temperature of 103 F (39.4 C) or higher — potentially a sign of serious COVID-19 disease.

## What is considered fever?

Despite the new research, doctors don’t consider you to have a fever until your temperature is at or above 100.4 F. But you can be sick if it’s lower than that.

## What is hotter than Fahrenheit?

100 degrees Celsius is the hotter one. Water boils at 100 degrees Celsius or 212 degrees Fahrenheit. 100 degrees Fahrenheit is a really low fever.

## What temperature will it snow?

Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, the snow will reach the ground.

## How cold can water get?

Chemists have discovered just how cold water can get before it must freeze. How low can you go? For water, the answer is -55 degrees Fahrenheit (-48 degrees C; 225 Kelvin). University of Utah researchers found that is the lowest temperature liquid water can reach before it becomes ice.

## What’s the temp of absolute zero?

At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.

## What is half of 0 Celsius?

0 degrees Celsius is equal to 273.15 degrees kelvin. So half of zero degree would be 273.15/2 which is equal to 136.575 degree kelvin.

## Which is hotter 273 kelvin or 0 degrees Celsius?

ANSWER: Short answer: A temperature of 273 Celsius (Centigrade) is twice as hot as zero degrees Celsius.

## Can I have COVID-19 if I have fever?

If you have a fever, cough or other symptoms, you might have COVID-19. Most people have mild illness and are able to recover at home.

## What forehead temperature is a fever?

The following thermometer readings generally indicate a fever: Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.

## How do you bring down a fever?

Rest and drink plenty of fluids. Medication isn’t needed. Call the doctor if the fever is accompanied by a severe headache, stiff neck, shortness of breath, or other unusual signs or symptoms. If you’re uncomfortable, take acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or aspirin.

## What’s the coldest thing on Earth?

A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and volume has ever come to absolute zero.
