Kelvin scale

Question 1

True or false:
The amount of pressure that a gas exerts on its container is dependent on the temperature of the gas

Answer 1

True

Particles move with more energy as their temperature increases

As the temperature of the gas decreases, the pressure on the container also decreases
In 1848, Mathematician and Physicist, Lord Kelvin, recognised that there must be a temperature at which the particles in a gas exert no pressure
At this temperature they must no longer be moving, and hence not colliding with their container

Question 2

What is absolut 0?

Answer 2

The temperature at which the molecules in a substance have zero kinetic energy

absolute zero, it is not possible to remove any more energy from it

0 k (kelvin) = -273 c

Question 3

What number does teh kelvin scale begin?

Answer 3

0

An increase of 1 K is the same change as an increase of 1 °C

This means a temperature in Kelvin will never be a negative value

Question 4

How to convert between K-c and viec versure?

Answer 4

K-c (-273)
c-K (+273)

Question 5

True or false:
The temperature (in Kelvin) is proportional to the average kinetic energy of the molecules

Answer 5

True

So if teh kintetic engery wa slow the temperture would also be low where as if thekintectic enegry was high the temeprture would also be high
