Problem Statement:

A three-liter empty canister weighs 370g. What pressure will the canister exert on a horizontal surface if it is filled with gasoline? The area of the bottom of the canister is 400 cm².

Solution:

To solve this problem, we need to calculate the pressure exerted by the canister when it is filled with gasoline. Pressure is defined as the force per unit area. In this case, the force is the weight of the canister and the area is the bottom surface area of the canister.

First, let's calculate the weight of the canister when it is empty. We are given that the mass of the empty canister is 370g. The weight can be calculated using the formula:

Weight = mass x gravitational acceleration

The gravitational acceleration is approximately 9.8 m/s². Converting the mass to kilograms:

Weight = 0.37 kg x 9.8 m/s²

Now, let's calculate the pressure exerted by the canister when it is filled with gasoline. The pressure can be calculated using the formula:

Pressure = Weight / Area

The area of the bottom of the canister is given as 400 cm². Converting it to square meters:

Area = 400 cm² = 0.04 m²

Substituting the values into the formula:

Pressure = (0.37 kg x 9.8 m/s²) / 0.04 m²

Calculating the pressure:

Pressure = 90.25 Pa

Therefore, the canister will exert a pressure of 90.25 Pascal (Pa) on the horizontal surface when it is filled with gasoline.
