Kelvin
The Celsius scale is a temperature scale where water freezes at 0 degrees and boils at 100 degrees at standard atmospheric pressure. It is based on the properties of water, making it a commonly used scale in science and everyday life. It is widely used globally for measuring temperature.
Temperature is typically measured on an interval scale, as it has equal intervals between each level but does not have a true zero point. However, in some contexts (such as in Kelvin scale), temperature can be considered a ratio scale where absolute zero represents a true zero point.
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.
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).
True. When the temperature of water drops to 0 degrees Celsius, its molecules slow down and form regular patterns, creating a crystalline structure.

No, the Celsius scale sets zero degrees as the freezing point of water and 100 degrees as the boiling point of water, with the scale divided into 100 equal parts between these two points. Water condenses at 100 degrees Celsius.
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).
Yes, that is true.

not true
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.
If that statement is true, it is expressed in Fahrenheit degrees.
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.
this is true. Singapore is near the epuater,thus the temperature never goes below 20 degrees
