If it's 0 degrees F outside today, and its supposed to be twice as cold tomorrow....?

Question

how cold will it be outside tomorrow?

Answer 1

Meteorologists use words like cold, cooler, milder, warmer, etc. according to a code that is based on the actual temperature and the average temperature for that day.

If the temperature is to be twice as cold the day after - disregarding that it is now - it means that it will be twice the difference between today's temperature and what is the average. Hence is the temperature is supposed to be say 10 F today but it is 0; tomorrow will be -10 F.

That's the way it is. But ... your question was supposed to be a trick, right?

Answer 2

Well, if cold is defined as the inverse of hot, then twice as cold would mean half as hot.  Using that definition:

0 degrees f = 255.37 degrees K

half of that is 127.685 degrees K

which is -229.8 degrees F

And that obviously isn't going to happen.

Answer 3

all i kno is that the temp isnt going to b 0 degrees bcuz  if it's twice as cold then it cant be the same temp as it was the day b4. so its in the negatives

Answer 4

Then it's 0 degrees.

0 + 0 = 0

Answer 5

If it is 0 degrees F today, to find out how cold it will be tomorrow is done by changing it into degrees C.  0 degrees F = -17.77 so multiply that by 2 = 35.54 degrees C which is -31.97 degrees F

Answer 6

wtf? where i live it a 100 degrees F. where the he** do you live?

Answer 7

i think the answer would be relative to what the asker's idea of cold is... but if you want to try to make it into a math problem, i would change fahrenheit to celsius.  0 degrees fahrenheit is about -18 degrees celsius.  if you want to consider "cold" as being 0 degrees celsius (although i would say it is cold way before 0 degrees celsius-->32 degrees fahrenheit), then it would be twice that temp, or -36 degrees celsius

Answer 8

0 f  i have no clue and i am a engineering major lol

Answer 9

sence 0x2=0

then it'll be 0 degrees out

right?

Answer 10

0 degrees because you can't multiply 0 by anything, so the temp will be the same

0 x 2 = 0

Answer 11

0 F?

Answer 12

You need to consult a psychrometric chart for the answer. It's not just a matter of multiplying 2 times 0 - you alsohave to consider the amount of moisture in the air - the humidity, the dew point, the pressure, the heat content of the air, the enthalpy, etc.

Here is a chart you can use to look up your question.

Let's assume 50% humidity - You can see at 0 F and 50% humidity, there are about 3 BTU per pound of dry air. Twice as cold would be half the heat. At 1.5 BTU per pounds of dry air, and 50% humidity, the temperature is about -1 F.

Answer 13

theres really no such thing as "twice as cold" now if you meant that the temperature will be twice what it was today then it will be 0 degrees because 2*0=0

Answer 14

The answer is -31.999 degrees F.  You convert the temp in Fahrenheit to Celsius, multiply by two, and then convert back to Fahrenheit.

Answer 15

0 degrees. Anything times 0 is 0.

Answer 16

lol find the kelvin temperature from that and then divide it by two.

k = ((Fahrenheit temp) + (459.67)) / (1.8)

k = 459.67 / 1.8

k = 255.4

255.4 / 2 = 127.7K

lol. It'll be 127.7K tomorrow. Probably read too much into that, but so what :)

Answer 17

The coldest possible temperature would be one in which there is no energy in a system. Kelvin is a temperature scale that is based at this point - 0 degrees kelvin is absolute zero (said point). 0 Degrees Fahrenheit is 255.372222 kelvin. Dividing by two produces 127.686111 kelvin. Converting back to Fahrenheit produces  -229.83500 degrees Fahrenheit.

For future reference absolute zero is -459.67 degrees Fahrenheit.

Also note while Celsius uses the same "sized" units as kelvin, Celsius is not based at absolute zero.

Answer 18

OK so it is 0 F out side. Now you have to convert is to Kalvin. So 0F is 255.372222 kelvin. Now divied that by 2 and get 127.686111 kelvin. no convert back to F and get -229.83500 degrees Fahrenheit.

-229.83500 degrees Fahrenheit
