All Charles Law states is that at constant pressure the volume of a gas is proportional to the temperature of the gas.

This can be written as a linear equation:

y = mx + c

where y = volume, x = temperature and m = constant of proportionality.

As such, it doesn't matter what scale is used to measure the volume or the temperature as long as they are both linear so that when the graph of volume against temperature is drawn it is a straight line.

The constant of proportionality will vary depending upon the scale used to measure the volume (and the scale used to measure the temperature).

In scientific use, the Kelvin scale is most likely to be used; but as the Kelvin scale has a direct linear conversion to other temperature scales, any will do.

Using Celsius results in:

V = mK + c

→ Y = m(C + 273.15) +c

→ y = mC + 273.15m + c

→ y = mC + d

(where d = 273.15m + c) which is again a linear equation, with the same constant of proportionality but a different intercept.

Using Fahrenheit results in:

y = mK + c

→ y = m(5/9 × F + 459.67) + c

→ y = (5/9 × m)F + 459.67m + c

→ y = nF + e

(where n = 5/9 × m, e = 459.67m + c) which is again a linear equation, but with a different constant of proportionality and a different intercept.

When using Charles law the units of temperature can be either Kelvin or degree Celsius?

Yes, that is correct. Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming pressure and amount of gas are constant. The temperature can be measured in Kelvin or degrees Celsius because they both have the same unit size and are related by a simple conversion factor (Kelvin = Celsius + 273.15).


What is the unit of measurement for temperatures?

It is degree Celsius, or degree Fahrenheit, or degree Kelvin or Rankine


What is the commonly used unit in measurement of temperature in a laboratory?

either kelvin, celsius, degree, or boiling point


How are celsius and kelvin alike?

A 1 degree increase in either is the same increase in the amount of thermodynamic temperature. In layman's terms, a 1 degree increase in either feels the same.


What is a thermometer unit?

A thermometer unit is a standard scale used to measure temperature. Common units include Fahrenheit, Celsius, and Kelvin. Temperature readings are expressed using these units to provide a standardized way of understanding and communicating temperature measurements.


What is the SI unit of temperature?

The unit is the Kelvin. Zero on the Kelvin scale is the coldest possible temperature, absolute zero. The scale increases by the same degree intervals as the Celsius scale but since Kelvin starts at absolute zero, the values are all higher. For example, it is 273.15 K when it is 0°C (Celsius). Kelvin "K" It is KELVIN!!!!! Either Kelvin, or Celsius. Both are used with the SI K degreeskelvin


When do particles have no kinetic energy?

At zero degrees kelvin, absolute zero. This is also the temperature at which some elements display the Bose-Einstein condensate, theorized by Einstein but not demonstrated until decades after his death.


What is the IS unit for temperature?

The units of temperature are degrees. You can measure degrees in either Fahrenheit, Celsius, or Kelvin.


What is 30celcius in kelvin degrees?

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 86 degrees Fahrenheit.


What is a valid unit for specific heat?

Joule/kilogram-kelvin The SI unit is joules / kelvin. This is valid for an object of any size, but if you want the typical specific heat for a certain type of material, you have to standardize it, resulting in either joules / (kelvin x kilogram) or joules / (kelvin x mole).


What are the units of temperature called?

The units or measurement of temperature are in degrees. You can measure degrees in either Fahrenheit, Celsius, or Kelvin.In the US we measure in Fahrenheit degrees. In the metric system, you also use Celsius degrees. However, the SI unit of temperature is called the kelvin. It depends on where you are and what kind of temperatures you are measuring.oC,oF and K (statements of Kelvin temperatures do NOT use the degree mark)


What is the relation between Celsius Fahrenheit and Kelvin scales?

Celsius and Fahrenheit scales are used to measure temperature, with Celsius being widely used in most countries while Fahrenheit is mainly used in the United States. Kelvin is an absolute temperature scale based on the properties of gases at different temperatures, where 0 Kelvin is absolute zero. The relationship between these scales is that Celsius and Kelvin have the same size degree (1°C = 1 K), while Fahrenheit degrees are smaller than Celsius degrees.
