Presentation Transcript

### Particles In Action

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

• recognise that the Kelvin temperature of a gas and the average kinetic energy of its particles are directly proportional.

• Draw the particles in a solution which has been heated and one that is cold.

• Change your movement according to the volume.

Celsius to Kelvin?http://www.visionlearning.com/library/module_viewer.php?c3=1&mid=48&l

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

Kelvin to Celsius?http://www.visionlearning.com/library/module_viewer.php?c3=1&mid=48&l

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

Making Thermometershttp://www.visionlearning.com/library/module_viewer.php?c3=1&mid=48&l

• Fill a bowl with crushed ice.

• Put a little coloured dye in the flask, then fill it to the top with crushed ice. Stand it in the bowl with crushed ice and leave it for 15 mins.

• Push the rubber bung on, and mark the level of the risen liquid.

• Then put the flask into a water bath and leave for 15 mins.

• Mark the new level.

• Divide the distance between the two marks into 5 equal divisions. Each division will represent 10 degrees.

• Leave the flask on the bench for 15 mins, and mark the new level.

How would you describe this relationship?http://www.visionlearning.com/library/module_viewer.php?c3=1&mid=48&l

Summaryhttp://www.visionlearning.com/library/module_viewer.php?c3=1&mid=48&l

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).
