For a given amount of gas showing ideal behaviour, draw labelled graphs of:
(a) The variation of\(P\)with\(V\)
(b) The variation of \(V\)with\(T\)
(c) The variation of \(P\)with\(T\)
(d) The variation of \(\frac{1}{P}\)with\(V\)
Why are sharp knives more effective than dull knives (Hint: think about the definition of pressure)?
A high altitude balloon is filled with \({\rm{1}}{\rm{.41 \times 1}}{{\rm{0}}^{\rm{4}}}{\rm{\;L}}\) of hydrogen at a temperature of \({\rm{2}}{{\rm{1}}^{\rm{^\circ }}}{\rm{C}}\) and a pressure of745 torr. What is the volume of the balloon at a height of20Km, where the temperature is \({\rm{ - 4}}{{\rm{8}}^{\rm{^\circ }}}{\rm{C}}\) and the pressure is \({\rm{63}}{\rm{.1 torr}}\)?
Methanol,CH3OH, is produced industrially by the following reaction:
Assuming that the gases behave as ideal gases, find the ratio of the total volume of the reactants to the final volume.
A sample of a compound of xenon and fluorine was confined in a bulb with a pressure of 18 torr. Hydrogen was added to the bulb until the pressure was 72 torr. The passage of an electric spark through the mixture produced Xe and HF. After the HF was removed by reaction with solid KOH, the final pressure of xenon and unreacted hydrogen in the bulb was 36torr. What is the empirical formula of the xenon fluoride in the original sample? (Note: Xenon fluorides contain only one xenon atom per molecule.)
