3. In automobile engine the gaseous fuel air mixture enters the cylinder and is compressed by a moving
piston before it is ignited. If the initial cylinder volume is 990&m'. After the piston moves up the
volume is 90cm¹. The fuel air mixture initially has a pressure of I atm and final pressure is 11 atm.
Do you think this change occurs according to Boyle's law?
4. A perfect elastic balloon filled with helium gas has a volume of 1.25x10'dm' at 1.00 atm and 25°C on
ascending to the certain altitude where temperature is 15°C the volume of the balloon becomes
1.208x10'dm'. Show that this data satisfies the Charle's law.
5. Discuss the effect on volume of gas by change in temperature at constant pressure.
