Think about what surrounds us all the time.
Define gauge pressure.

True or False: An isothermal process involves a change in temperature.
Recall the definition of isothermal.
A manometer is connected to a tank of air at a pressure of 2 MPa. How high would the water rise in a manometer? Assume the density of water is 1000 kg/m³.
Remember to keep units consistent.
Two different gases, Helium and Nitrogen, are kept at similar volumes and temperatures. If the molecular mass of Helium is significantly lower, how would this differ in terms of pressure? Explain mathematically.
Apply the formula PV = nRT and consider the relationship between pressure and molecular mass.
