Why do you use kelvin temperature scale?
The Kelvin scale starts at a true zero; 0o K is the temperature at which there is actually no heat. Therefore, you get a true measure of heat using this system; an object at twice the temperature in kelvins is actually twice as hot. That is not true of other temperature scales such as Celsius or Fahrenheit.
True or false when the temperature of water drops to 0 degrees Celsius its molecules form regular patterns which are crystals?
True
-273.15 celsius is the temperature of absolute zero?
Absolute zero is 0 degrees Kelvin, -273.15 degrees Celsius, and −459.67 degrees Fahrenheit. Short answer: No. Technically, absolute zero could be defined to be whatever number you wanted on some arbitrary scale. However, on the two commonly used scales - Fahrenheit & Celsius - 273.15 is not absolute zero. I'm guessing that you actually meant -273.15. On the Celsius scale, this is absolute zero (to 5 significant figures).
How do you use kelvin scale?
The Kelvin scale measures temperature. You can use it the same way you would use the Fahrenheit scale or the Celsius scale, but it also has an additional use. Since the Kelvin scale starts at the true zero of temperature, when there is no random thermal motion, rather than starting at some arbitrary point such as the freezing point of water (Celsius) or the coldest temperature that was obtainable in the laboratory at the time the Fahrenheit scale was first devised, you can make much more meaningful comparisons in Kelvin. If something has twice the temperature in Kelvin than something else has, then it actually is twice as hot. That is not true of other temperature scales. 20oC is not twice as hot as 10oC. But 20oK actually is twice as hot as 10oK.
Why was kelvin scale was made?
The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point of this scale is equivalent to -273.16 °C on the Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale". At the freezing point of water, the temperature of the Kelvin scale reads 273 K. At the boiling point of water, it reads 373 K. Whereas the Kelvin scale is widely used by scientists, the Celsius or Fahrenheit scales are used in daily life. These two scales are easier to understand than the large numbers of the Kelvin scale. Could you imagine waking up to your radio and hearing the DJ give a weather report like this: "It's going to be a beautiful day today with sunny skies and a balmy temperature of 297 K!" That's 24 °C or 75 °F.
Would the Celsius scale zero degrees is assigned to the temperature at which water condenses?
true
Is 300 degrees three times hotter than 100 degrees?
No. The only time that such a statement might be true is in the absolute scale for temperature - which is measured in Kelvin (not degree Kelvin).

True or false on the celsius scaleroom temperature is about 21 degrees?
Yes, that is true.
Why is the temperature of ice stays 0 degrees when it melts so it is not gaining heat not true?
not true
Why do scientists measure temapture in kelvins or degrees Celsius's rather than degrees Fahrenheit?
This is because the Kelvin scale is the only absolute scale. This means that 20 K is twice as hot as 10 K - a relationship which is not true for the other measurement scales used for measuring temperature. It also means that the 0 point of the Kelvin scale is the minimum possible temperature: the point at which all thermodynamic would cease - if this temperature could be attained. The Celsius scale is closely linked to the Kelvin scale because a Celsius degree is the same as a Kelvin.The Fahrenheit scale is based on too many arbitrary points: a 0 which is the coldest temperature of an ice and salt mixture, 32 as the freezing point of water, a 180 degree spread between the freezing and boiling points of water. Nothing really that fits in with anything that matters. The only redeeming feature of the F scale is that the degrees are small enough that in clod places, where differences of half degrees do matter, the F scale is more useful.
Does plutos temperature reach 375 degrees Fahrenheit?
It's not true
Is the average temperature in Switzerland 50 degrees Fahrenheit or Celsius?
If that statement is true, it is expressed in Fahrenheit degrees.
What is true about 18 degrees Fahrenheit and 18 degrees Celsius?
18 degrees Fahrenheit is below the freezing point of water (quite cold) and 18 degrees Celsius is a comfortable temperature. In cases like these where you are comparing temperatures on two different scales, it is better to convert them to one scale. The differences would be more obvious.
It never goes below 20 degrees in Singapore is it true?
this is true. Singapore is near the epuater,thus the temperature never goes below 20 degrees
-273.15 is the temperature of absolute zero true or false?
In degrees centigrade, yes, correct.
True or false when the temperature of water drops to 0 degrees Celsius its molecules form regular patterns which are crystals?
True
