Calculation of Pressure Increase in the Pot

To calculate the increase in pressure in the pot when water is poured into it, we need to use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

In this case, the force is the weight of the water and the area is the area of the bottom of the pot.

Given: - Area of the bottom of the pot = 1300 cm² - Volume of water poured into the pot = 3.9 liters

To calculate the weight of the water, we need to know the density of water. The density of water is approximately 1 gram/cm³ or 1000 kg/m³.

Converting the volume of water from liters to cubic centimeters: - 1 liter = 1000 cubic centimeters

Therefore, the volume of water poured into the pot is: - 3.9 liters = 3.9 * 1000 = 3900 cubic centimeters

To calculate the weight of the water: - Weight = Volume * Density

Substituting the values: - Weight = 3900 cm³ * 1 g/cm³ = 3900 grams

Now, we can calculate the pressure increase in the pot: - Pressure = Weight / Area

Substituting the values: - Pressure = 3900 grams / 1300 cm²

To convert grams to kilograms: - 1 kilogram = 1000 grams

Therefore, the pressure increase in the pot is: - Pressure = 3900 grams / 1300 cm² = 3 kilograms / 1 cm²

The pressure in the pot will increase by 3 kilograms per square centimeter when 3.9 liters of water are poured into it.
