### Transcript of "Gas Phase G8"

1. 1. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe The Gas Phase K Warne Bang! Bang! Bang!
2. 2. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Kinetic theory of Matter 1. All Matter is made up of ______________. 2. Forces of ______________________________ exist between particles. 3. The particles are in a state of ___________________ motion. 4. Particles collide with __________________ and _____ ______________________. 5. Particle collisions are ____________________. (Particles not deformed.) 6. Particles in a given sample do not have the same _____________________.
3. 3. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Gases Motion – Rapid random (speed and direction) motion. Fill any space. Forces – very weak forces - negligible (can be ignored in most situations) Energy – very high energy - kinetic energy. Pressure results from gas particles ………………. with the …………………………………………... Bang! Bang! Bang!
4. 4. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Effect of Temperature If temperature of a fixed mass of gas is increased while the volume is kept constant then the pressure will …………………….. Increasing temperature • increases the ……………… of the particles. • The particles will collide …………………….. with the container • collisions will be ………………………………... P T increases .: P …………………….( V = const.) ……………… increase ……………… increase
5. 5. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Temp & Volume • The volume of a given amount of ideal gas is directly proportional to the Temperature (Kelvin) provided the amount of gas and the pressure remain fixed. If Temperature increases Volume also increases. (P=const.) • Eg: A hot air balloon as the air is heated… the air expands and fills the balloon. V (cm3) T (/K)
6. 6. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Kelvin Temperature pV  T Reference points: • Absolute zero • Triple point of water (273.16K) At constant V • P1/P2 = T1/T2 • If “2” = triple point • Then P1/Ptr = T1/Ttr P T 0 0 Ttr Ptr
7. 7. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> ScienceCafe Hi - This is a SAMPLE presentation only. My FULL presentations, which contain loads more slides (with all the gaps filled in) as well as other resources, are freely available on my resource sharing website: www.sciencecafe.org.za (paste into your browser if link above does not work) Have a look and enjoy!
