Metric Length and Temperature: the Kelvin Scale

The video tutorial introduces the Kelvin temperature scale, explaining that it is used by scientists and measured in Kelvins. It demonstrates how to convert Celsius to Kelvin by adding 273 to the Celsius temperature. The tutorial highlights the significance of the Kelvin scale, noting that 0 Kelvin represents absolute zero, the lowest theoretical temperature possible.

What is the basic unit of temperature in the Kelvin scale?

• Kelvins

• Celsius

• Fahrenheit

• Degrees

How do you convert 15 degrees Celsius to Kelvin?

• Subtract 273 from 15

• Multiply 15 by 273

• Divide 15 by 273

• Add 273 to 15

What is the Kelvin equivalent of 15 degrees Celsius?

• 300 Kelvins

• 273 Kelvins

• 288 Kelvins

• 258 Kelvins

Why is the Kelvin scale particularly useful to scientists?

• It is used in everyday temperature measurements.

• It is based on the freezing point of water.

• It is easier to calculate than other scales.

• It starts at absolute zero, the lowest theoretical temperature.

What is absolute zero in the Kelvin scale?

• 15 Kelvins

• 100 Kelvins

• 0 Kelvins

• 273 Kelvins
