Question
10. (6 Pts) W hat is the definition of Temperature? Based on the Maxwell's distribution shown below for a compound A, explain the effect of increasing temperat about possible change in physical state) ure on the molecule. (your answer must talk Lower T afheatit fe -n.reso.eh bali Higher T int' . Kinetic Energy 11. (5 Pts) Below is the structure of Fluorite (FCC arrangement of the Ca atoms + one F in each hedral site). How many Ca and F are in each fluorite unit cell? You MUST show your work to get full credit!Explanation / Answer
Temperature is a measure of hotness or coldness of environment.If you add heat ,the temperature will rise.
At particular temperature,different molecules of gas possess different speeds.Due to collision among molecules and to walls of containers,their speed keeps on changing.Due to this some molecules speed up and some are slow down.So molecules speed remain constant at constant temperature.
In maxwell-boltzmann distribution curve fraction of molecules possessing particular speed plotted against their correspondin speeds at particular temperature.
In the above diagram of maxwell distribution, as temperature increases
1 )the peak shift forward showing that most probable velocity increases
2)peak shift downwards showing fraction of molecules possessing most probable velocity decreases
3)curve is flattened in middle showing more molecules have speeds near to most probable speed
4)fraction of molecules having higherv speed increase
5)fraction of molecules having lower speed decreases.
