1. If you are exposed to water vapor at 100C, you are likely to experience a worse burn than if you are exposed to liquid water at 100C. Why is water vapor more damaging than liquid water at the same temperature?
2. If the pressure of a gas is due to the random collisions of molecules with the walls of the container, why do pressure gauges-even very sensitive ones-give perfectly steady readings? Shouldn't the gauge be continually jiggling and fluctuating? Explain?
