A cylindrical container with a height of 1.5 m and a radius of 0.3 m is filled with water. The pressure at the bottom of the container is measured. Calculate the pressure exerted by the water at the bottom of the container. Additionally, if the water is heated and the temperature increases by 50°C, determine the change in pressure due to thermal expansion, assuming the coefficient of volumetric expansion for water is 0.000214 °C⁻¹. Show all your workings.
