The length of the mercury coloumn in a mercury thermometer is 5cm when the bulb is immersed in water at the triple point (273.16k). What is the temperature if it reads 6.0cm? What will the length of coloum be if immersed in boiling water (at steam point)? I'm new to this forum, but would really appreciate any help you guys can give (need help asap!). I've tried using pv = nKT etc, but can't apply it. All your hints would be welcome!
