The Gas Laws: temperature

Question 1

What is temperature the measure of?

Answer 1

Temperature is a measure of the degree of hotness of an object

Question 2

What are the two relevant scales of temperature used in science?

Answer 2

Celsius scale (centigrade scale) and the Kelvin scale (absolute scale)

Question 3

What did Lord Kelvin propose? (3)

Answer 3

He proposed that the energy of molecules of a gas should reach zero at -273 degrees C.

He proposed that the temp -273 degrees C should be considered the lowest possible temperature (absolute zero).

He set up a new scale of temperature with the zero mark at absolute zero and each degree rise was the same as a degree rise on the celsius scale.

Question 4

In theory, what would a gas be like when at the zero mark of the kelvin scale?

Answer 4

In theory, at the zero mark of the kelvin scale, a gas would occupy zero volume if it could be cooled indefinitely without becoming a liquid or a solid.

Question 5

How is temperature converted from the celsius scale to the kelvin scale?

Answer 5

by adding 273
