Challenge Problems
Push your limits with challenges.
Question 1
You have a mercury barometer with a height of 760 mm. Calculate the atmospheric pressure at this height if the density of mercury is 13.6 g/cm^3.
💡 Hint: Remember to convert density from g/cm^3 to kg/m^3 and height from mm to m.
Question 2
A capillary tube with a diameter of 2mm is placed in water. Calculate the height to which the water will rise if the surface tension of water is 0.072 N/m and the contact angle is 0 degrees.
💡 Hint: Make sure to use the density of water, 1000 kg/m^3.
