1. The highest surface temperature on any of the solar system’s planets is found on Venus. Partly
because of its nearness to the sun and partly because of the extreme pressure of its
atmosphere, the average daytime temperature on Venus is 453°C. What is this temperature in
degrees Fahrenheit and in kelvins?
Solution:
2. The temperature at Earth’s center is estimated to be about 5,100 K. Express this temperature
in both degrees Celsius and degrees Fahrenheit.
Solution:
3. What will be the gauge pressure and the absolute pressure of water at depth 12 m below the
surface? (ρwater = 1000 kg/m3, Patm = 101.325 kPa)

4. A manometer connect to pipe indicates a negative gauge pressure of 50 mm of mercury. What
is the absolute pressure in the pipe in Pa? ( = 13600 kg/m3, Patm = 101.325 kPa)
Solution:
5. Determine the atmospheric pressure at a location where the barometric reading is 700 mm Hg
and the gravitational acceleration is g = 9.81 m/s2. Assume the temperature of mercury to be
10◦C, at which its density is 13,570 kg/m3.
Solution:
