Particles In Action. Lesson 1: Absolute Zero. Learning Objectives: describe the term absolute zero convert between Kelvin and Celsius scales of temperature describe how the temperature of a gas relates to the speed and kinetic energy of its particles
Particles In Action
To change 100 °C into Kelvin just add 273.
So 100 °C = (100 + 273) K = 373 K.
What are the following temperatures in Kelvin?
0 °C, 20 °C, 37 °C, 500 °C, -5 °C, -169 °C
To change 100 K into Celsius just subtract 273.
So 500 K = (500 - 273) K = 227 °C.
What are the following temperatures in Celsius?
0 K, 200 K, 300 K, 1 000 K
How would you describe this relationship?
At __________ (–273 ºC or 0 K) particles __________ moving. You convert ºC to K by adding __________. Increasing the __________ increases the speed of the particles. The _________ in a gas are continually colliding with each other. The kelvin temperature and the average __________ energy of the particles are directly __________ to each other (i.e. double the __________ temperature, __________ the kinetic energy).
kinetic particles proportional stop temperature
