Water expands when heated. Suppose a beaker of water is heated from 10℃ to 90℃. Does the pressure at the bottom of the beaker increase, decrease, or stay the same? Explain.

The Pressure Increases

Explanation:

When the water is heated from 10℃ to 90℃ the pressure at the bottom of the beaker will also increase. For a closed system with liquid contents that is water, the pressure will always increase with a rise in temperature.

       By using the formula;  

     

       where,

      V1 & V2 are the volumes at the initial level and final level, both the volumes are the same(ignoring pressure distention), T1 & T2 are the temperatures and   P1 & P2 are the pressures.

      Therefore, we get the pressure excluding the volumes as -

     

Hence, according to the above explanation, if the temperature of the water increases then the pressure at the bottom of the beaker is also increased.
