A pressure for a gas is measured as 467 kPa. What is the pressure in atm?
If the barometric pressure is 107.4 kPa, what is the pressure in kPa of the gas in the open end mercury manometer shown at right? (in the picture the atm pressure > gas pressure, and the height difference is 98 mm)
The Pressure of an Ideal gas,
measured in kPa, is related to its volume, V, and temperature, T,
by the equation:
PV=0.23T.
The temperature is measured with an error of 8 kelvin and the
volume is measured with an error of 0.6m^3. If it is known that the
actual values are T=234 kelvin and V=4m^3, what is the estimated
maximum error in the measurement of the pressure? Round your answer
to 4 decimal places.
