Pressure in Different Liquids at a Depth of 1m

To determine which liquid will have a higher pressure at a depth of 1m, we can use the concept of hydrostatic pressure. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. It depends on the density of the fluid and the depth at which it is located.

According to the question, we need to compare the pressure at a depth of 1m in different liquids: water, sulfuric acid, and alcohol. To do this, we can refer to a table of densities of these liquids.

Comparing Densities of Water, Sulfuric Acid, and Alcohol

Here are the densities of the liquids mentioned:

- Water: 1000 kg/m³- Sulfuric Acid: 1840 kg/m³- Alcohol (Ethanol): 789 kg/m³

Calculating Pressure at a Depth of 1m

To calculate the pressure at a depth of 1m, we can use the formula:

Pressure = Density × Acceleration due to gravity × Depth

The acceleration due to gravity is approximately 9.8 m/s².

Let's calculate the pressure at a depth of 1m for each liquid:

- Water: Pressure = 1000 kg/m³ × 9.8 m/s² × 1m = 9800 Pa - Sulfuric Acid: Pressure = 1840 kg/m³ × 9.8 m/s² × 1m = 18032 Pa - Alcohol: Pressure = 789 kg/m³ × 9.8 m/s² × 1m = 7722 Pa

Conclusion

Based on the calculations, the pressure at a depth of 1m will be higher in sulfuric acid compared to water and alcohol. The pressure in water will be the lowest, followed by alcohol.

Please note that these calculations assume ideal conditions and do not take into account factors such as temperature and pressure variations.
