today the temperature is 0(zero),tomorrow weather is 2 times colder than today,what is temperature tomorrow?

Question

plz give me the best answer,if your answer right.u have prize.surely!merC.

Answer 1

In order to compare temperatures directly for heat content you must use a temperature where zero means absolute zero, the coldest possible temperature in the universe.

In the Celsius scale this is -273 deg (in Fahrenheit -459 deg), so zero degrees Celsius is the same as 273 degrees Kelvin (the absolute temperature scale based on Celsius degrees).

Twice as cold is the same as half the heat, so divide 273 by 2 and get 136 Kelvin = -136 Celsius, a temperature that does not occur on earth as far as I know.

Notice that the freezing point of water in Fahrenheit is not 459 Absolute, but 459+32, or 491. Divide this by 2 and you get 245 Absolute, or 459-245=214 below zero!

Answer 2

Temperatures are measured in degrees C because zero is defined as the temperature at which water freezes, and 100 as the temperature tat which water boils (32 and 212 in Farenheit).

However, here we are talking about temperature, not heat, and the zero and 100 scale is arbirary. Temperatures lower than zero are given negative values.

Heat is different from temperature: it is a measure of the kinetic energy of the molecules of the matrial being measured (water, air, whatever), and there is an absolute limit, below which temperature cannot fall, and is reached at the state where there is no kinetic energy, and no heat.

It can be shown that this temperature is minus 273.16 deg C, and is known as absolute zero. Lower temperatures cannot be reached. On the absolute temperature scale (degrees Kelvin, or K), zero degrees C is 273 deg K, and a warm summer day of 27 degrees celsius is 300 deg K. water boils at 373 deg K.


Heat is therefore a function of degrees Kelvin, and on that scale, something 'twice as cold" as zero C would be half the temperature Kelvin, or 273 divided by 2 = 136.5 degrees Kelvin. This is the same as minus 136.5 degrees C; which is pretty darn cold; seeing as how the lowest temperature ever measured on earth was minus 126 in Antarctica.

Answer 3

The global mean surface temperature is approximately 15 degrees C. This is a temperature which most people would describe as neither hot nor cold.

Today the temperature of 0 degrees is 15 less than average, so twice as cold tomorrow would be 30 less than average, or -15 degrees C.

Similarly, if 25 degrees C was called "hot", then 35 degrees C could be called "twice as hot".

Answer 4

Today's temperature is 0 and yours is 37, so it is -- 37 cold today.
Tomorrow is 2 times colder so it must be
2x(--37) from yours or
it must be 37 -- 74 = --37.
Tomorrows temperature will be -- 37.

Answer 5

Use the Kelvin temperature scale, based on absolute zero. There are no negative temperatures, no cold. Just amounts of being warmer than absolute zero. On that scale, if you double todays temperature, you may catch fire.

Answer 6

since todays temperature is zero and tomorrows temperature is 2x todays own then tomorrow will be 2 x o =o

Answer 7

If you mean the the figure value of temperature (you mentioned zero) is twice, the double remains zero.

But if you are talking about the physical value of cold it became twice, then that is not valid, there are no bases or methods to evaluate if the weather is cold by double or tribble.

You can say it's little bit cold or more cold and so on.

Answer 8

surely it could be 1000 times colder than zero degrees, and it would still be only zero degrees outside.... anything times zero is zero... its a trick question

Answer 9

freezing. HA. but you could use celcius ( not sure how to spell it) and get a number

Answer 10

still o
