See the Related Questions link to the left of this answer: "Why must you always use Kelvins when dealing with the ideal gas law?" Also, our understanding of gases is based on the kinetic theory of gases. This theory has to with understanding how fast gases move as a function of temperature. Since molecular motion stops at 0 K, everything is referenced to the kelvin scale, which is an absolute measurement of temperature. Celsius is just referenced to the freezing point and boiling point of water, which really has nothing to do with most gases!
What else can I help you with?
Why does the percent error calculation have to be performed in celsius rather than kelvin?
That is just utter nonsense. Kelvin is the absolute scale so percentages should be calculated in Kelvin and not Celsius.
What is the temperature scale preferred for gas calculations?
Kelvin is the temperature scaled preferred by scientists for doing pretty much everything rather than deciding to wear a coat or a bathing suit (though given the outside temperature in Kelvin it wouldn't take most of them long to make that determination either).
Why is the SI unit of temperature Kelvin but not Celsius?
Celsius and Fahrenheit are relative scales which are compared with freezing and boiling points of water. While kelvin is not relative and is an absolute scale. From graphical representation of Charles's when one extrapolate the graph straight, it will touch the zero volume at -273.16 Celsius or OK. This OK is the start or emergence of kelvin scale which is not related to anything, but absolute.
Melting point of ice in kelvin?
The diamond has no melting point. The triple point for carbon is about 11 MPa and about 4600 K. Rather than melting, carbon sublimes at about 3900 K.
Why is absolute zero only expressed in Kelvin and not celsius?
Absolute zero is defined as the point at which particles have minimal thermal energy. The Kelvin scale directly corresponds to this concept by setting absolute zero at 0 K. In contrast, the Celsius scale is defined by the freezing and boiling points of water, making it more suitable for everyday temperature measurements rather than extreme values.
Why does the percent error calculation have to be performed in celsius rather than kelvin?
That is just utter nonsense. Kelvin is the absolute scale so percentages should be calculated in Kelvin and not Celsius.
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 is the kelvin scale used rather than the celsius scale?
Because the Kelvin scale is an absolute scale. In the context of thermodynamics, 2 K is twice as "hot" as 1 K. And 3 K is three times as "hot". That is not true of the Celsius or Fahrenheit (or other temperature) scales.
What scale boils water at 373 degree's?
Firstly, temperatures measured in Kelvin (K) are not degrees but rather, just numbers. However, 373 K is the same as 100 degrees C. At that temperature, pure water begins to boil at sea level.
What does 225 K mean as a temperature reading?
The Kelvin scale uses the same degree size as Celsius, but starts 273.15 degrees lower, at absolute zero (in Celsius zero is the freezing point of water). So Kevin temperatures have a numerical value greater by 273.15. 225 K would therefore indicate a rather cold temperature of about -48.15° C (-54.67°F).
Is 135 degrees Kelvin hot or cold?
Extremely cold. It equates to minus 216.67 degrees Fahrenheit.
Why do scientists use the Kelvin and Celsius scale rather than the Fahrenheit scale?
Celsius is a very accurate measurement between the freezing and boiling points of water. 0 being freezing, and 100 boiling. Kelvin is the measurement of absolute zero, where particles stop moving altogether. Kelvin has the same conversion rating, only 0 Kelvin is -273 degrees Celsius. The Kelvin scale is an absolute scale. This means that 2 K is twice as hot as 1 K and so on. Neither the Celsius nor the Fahrenheit scales do that. The Centigrade (or Celsius scale are based on the freezing and boiling points of water (at normal pressure), the Fahrenheit scale was not: the 0 was the lowest temperature attained by ice and salt.
What temperature scale must always be used when working gas law problems?
PV = nRT You can use whatever you want essentially, however S.I units are generally preferred so you don't end up in a mess. P in pascals (Pa) V in metres (m3) n is just the number of moles R is the gas constant 8.3145x103 (JK-1mol-1) T is temperature in Kelvin (K) Converting Celsius to Kelvin is simple (degrees celcius + 273.15) = temperature in Kelvin Note:- if you keep pressure in Torr rather than Pa, you have to use a different value for the gas constant R.
What is the formula for converting celsius to Kelvin?
Celsius and Kelvin scales use the same size unit or "degree." But Kelvin has its zero point at absolute zero rather than the freezing point of water. Absolute zero (zero K) is about -273.15° Celsius.To convert Celsius to Kelvin, add 273.15. For example 100° C is 373.15 kelvins.To convert kelvins to Celsius, subtract 273.15. For very large numbers, such as 5000 K, the value (4726.85° C) is not going to be that different.
What is the difference between kelvin and centigrade?
Both are measures of temperature. Both have 100 Degrees between the freezing point and melting point of pure water at 1 atmosphere of pressure but the difference lies in the value of 0k and 0c. Zero centigrade is the freezing temperature of pure water where as Zero Kelvin is Absolute Zero, which is -273 Degrees Centigrade. Therefore water freezes at 273 Degrees Kelvin and 0 Degrees Centigrade. Water therefore boils at 373 Degrees Kelvin but 100 degrees Centigrade. (All assuming one standard atmosphere of pressure.)
What is the temperature scale preferred for gas calculations?
Kelvin is the temperature scaled preferred by scientists for doing pretty much everything rather than deciding to wear a coat or a bathing suit (though given the outside temperature in Kelvin it wouldn't take most of them long to make that determination either).
What is a temperature reading of 237 Kelvins equivalent to?
The Kelvin scale uses the same degree size as Celsius, but starts 273.15 degrees lower, at absolute zero (in Celsius zero is the freezing point of water). So Kevin temperatures have a numerical value greater by 273.15. 237 K would therefore indicate a rather cold temperature of about -36.15° C (-33.07°F).
