Which of the following apply to temperature and the kelvin scale. Select all that apply. 0 K is equal to -273 degrees Celsius. T
he term “degree” is not used with the Kelvin scale. Cryogenics is the study of very low temperatures and their effects. Gas can have a volume of 0. Scientists have been able to cool substance to absolute zero.
Statement 1: 0 K = -273 °C. This is true. This has come to be referred to as absolute zero which is very theoretical as it has never been attained.
Statement 2: °C is not used with Kelvin scale. This is true. Kelvin is a scale equivalent to °C and thus ° is not used with Kelvin scale and this would be a different scale all together which does not exist.
Statement 3: Cryogenics has been defined as the production and characteristics of materials at very low temperatures. Therefore, it can also be defined as a study and thus this statement is true.
Statement 4: Volume of gas at absolute zero is, theoretically, thought to be zero. This is due to the reasoning that at that temperature, all the gas will have condensed to liquid. However, absolute zero temperature has never been attained. Therefore, this statement is theoretically true.
Statement 5: Scientist have not yet cooled anything to absolute zero and thus this statement is false.
