Question

Select all that apply to temperature and the kelvin scale.

-Scientists have been able to cool substance to absolute zero.
-0 K is equal to -273 degrees Celsius.
-Gas can have a volume of 0.
-The term “degree” is not used with the Kelvin scale.
-Cryogenics is the study of very low temperatures and their effects.

Answer 1

Number one, two, theee and five

Answer 2

Answer: Option (2), (4) and (5)

Step-by-step explanation:

Absolute zero refers to the temperature from which there occurs no cooling. Scientists have not been able to cool any substance upto its absolute zero temperature. A temperature close to the absolute zero temperature is attained but it never exactly reaches the absolute temperature.

For the conversion from celsius scale to kelvin or from kelvin to celsius scale, it is universally taken to be 0 K= -273°C.

Gas can never be zero volume because gas is a matter and certain composition and thus has its own volume.

In Kelvin scale, k is used whereas in celsius scale, degree (°) is used.

Cryosphere refers to the study of the materials and their characteristics at a relatively very low temperature.

Thus, the correct answers are option (2), (4) and (5).
