What temperature scale has zero as it's lowest temperature?
The Kelvin scale (apex)
How do you use absolute zero in a sentence?
Nothing moves when the temperature is at absolute zero.
How is degree celsius and temperature related?
degree celsius and temperature are related because temperature is anything is measure of how hot or cold it is degree celsius is the metric unit of temperatureAnswer:I'm not sure what you're asking but . . . Celsius (centigrade) is a scale used to measure temperature (hot & cold). In the U.S. we usually use the Fahrenheit scale, but both scales do the same basic thing -- they measure temperature.Another scale is Kelvin. On the Kelvin scale 0 is absolute zero, meaning there is no longer any temperature.
Why is Kelvin scale adopted for chemical calculations?
There are two types of numerical scales available: relative and absolute. A relative scale arbitrarily (i.e. as judged by the person) assigns a point of origin that is said to be equal to "zero". While in some cases this makes measurement for some values quite simple (e.g. the freezing point of pure water is 0 Celsius), in other cases moving to the left of the zero mark (that is, producing negative values) could cause formulas to produce unintended results. On the other hand, an absolute scale relates the origin to some absolute and definite zero. In the case of the Kelvin, the "zero" chosen corresponds to the temperature where the kinetic energy of a perfect crystal of matter is equal to zero. For one thing, this resolves the difficulty of determining what "zero" actually stands for. Another advantage of the Kelvin scale is that it is incremented in absolute values, that is, all values are always positive. This eliminates the problem of factoring in negative values into a particular equation. Answer When doing chemistry, it is always a good idea to use Celsius or Kelvin, simply because it is measure of temperature that is understood in the majority of the world. Kelvin is simply more accurate to the hypothetical "absolute zero" than Celsius.
Why do scientists use Kelvin to measure temperature?
Because there are no negative numbers Many thermodynamic equations need absolute numbers. At 0 degrees Kelvin, molecules stop. It is absolute 0--it doesn't get colder. There is a direct correlation between Kelvin and Celsius. For Fahrenheit, the absolute scale is called Rankine.
Why do you use kelvin scale?
Kelvin Scale is an absolute temperature scale. This means that it starts at a different point than Celsius, its counterpart. This is why you must add 273.15 to a Celsius temperature in order to get a Kelvin temperature. The Kelvin scale starts at absolute zero whereas Celsius starts at the freezing point of water. Kelvin is used more often in science such as in the ideal gas equation. It is more convenient to use it than Celsius when dealing with very cold temperatures and with things like the Perfect Gas Laws which reference absolute zero.
What temperature scale does not use degree?
The temperature scale that has no negative values is the Kelvin scale, because it has its zero point at the lowest possible measurable temperature (absolute zero).The similarly based scale using Fahrenheit intervals (degrees) is the Rankine scale. The Kelvin scale starts at (the minimum) absolute zero. (0 K = -273 oC)
What is used to absolute temperature in the English system of measurement?
The Rankine scale is used. On that scale, you use Fahrenheit-size degrees, but the zero of the scale is at -459.67
Why you use kelivin in calculation instead of celsius and Fahrenheit?
Kelvin has the advantage that it is an absolute temperature scale - it starts from absolute zero. This simplifies several calculations; for example, in an ideal gas, at constant pressure, the volume of the gas is proportional to the absolute temperature. Similarly, calculations related to heat machines are simpler if an absolute temperature scale is used.
Why scientist use kelvin scale in their scientific experiment?
Because it is an absolute scale. There are no negative temperatures. With Kelvin, it makes sense to say that one temperature is twice another temperature, for example.
What measure temperature?
The basic unit is a Kelvin but it is common to use a degree Celsius. The Kelvin scale is absolute whereas the zero point on the Celsius scale is arbitrary.
What metric measures temperature?
The basic unit is a Kelvin but it is common to use a degree Celsius. The Kelvin scale is absolute whereas the zero point on the Celsius scale is arbitrary.
When do you use the Rankine Scale?
The Rankine scale is one of the temperature scales used when an absolute temperature scale is needed. The Rankine scale is useful in calcluations of oil or gas present in an oil or gas reservoir (one of the factors in the equations is the ratio of standard temperature to formation temperature; generally add 460 to the temperature in degrees Fahrenheit to obtain degrees Rankine).
What are the upper fixed points of the Celsius and Fahrenheit scale?
there is only one. ABSOLUTE ZERO. the lowest temperature witch can possible excist. further it is the same scale as Celsiuss. but with a sufferance of 273,15 degrees 0 Kelvin= -273,15 degrees Celsius.

What kelvin temperature is considered standard temperature?
The Kelvin Temperature scale is an absolute temperature scale to be used in the SI System.T in K = T in C + 273.15Applications involving the Ideal Gas Law or radiation heat transfer require use of absolutetemperature ( T in K )
Is Fahrenheit the best temperature to use?
No. Fahrenheit is the dinosaur of temperature scales. Kelvin is probably the best scale but it is not very well known. It is an absolute scale which means that 2 deg K is twice as hot as 1 deg K. It is the temperature scale used in the sciences. The second best is the Centigrade or Celsius scale since it is directly related to the Kelvin scale. It is used in most countries.
