I am no sure how to do this question? Do I have to use steam tables?## Homework Statement

a)

A scientist carries a thermometer, barometer, pan and gas camping stove up a mountain. At a certain point he collects water from a stream, boils it and measures the temperature of the steam condensing on the thermometer to be 98°C. What is the height of the column of mercury [itex] (density = 13560 kg m^{-3} ) [/itex] in the barometer?

b) Estimate the altitude of the scientist relative to sea level, assuming the density of air to be [itex] 1.186 kg m^{-3} [/itex] .
