SUMMARY
When heating water in a beaker from 10 degrees to 90 degrees Celsius, the pressure at the bottom of the beaker remains constant if the beaker is open, allowing for water expansion. However, if the beaker is closed and the water volume is fixed, the pressure will increase due to the constant mass of water and the increase in temperature. The mechanical equilibrium condition dictates that the total forces acting on the water must balance, with gravity and pressure forces being key factors in determining the pressure changes.
