It might not be efficient nor practical, but is it possible to design a jack/lifting device only using a heater to heat a gas which will then move a platform/ram/piston (which does the lifting)? Try designing such a device that is capable of lifting a 1969 Chevy Corvette as high as 2 meters. Feel free to choose the fluid and devise the design (e.g. a single large cylinder or several?) As above make sure that you: - - - Provide sufficient calculations and justification State assumption where necessary Remember that the ideal gas assumption only applies for certain conditions Don't all your forget previous knowledge
