Answer:

68.3 kilo Pascal is the pressure in the container.

Explanation:

To calculate the new pressure , we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume.

P_2\text{ and }V_2 are final pressure and volume.

We are given:

P_1=205kPa\\V_1=4.0 L\\P_2=?\\V_2=12.0 L

Putting values in above equation, we get:

P_2=\frac{P_1V_1}{V_2}

=\frac{205 kPa\times 4.0 L}{12.0 L}=68.3 kPa

68.3 kilo Pascal is the pressure in the container.

tekilochka [14]

Answer:

500N/m²

Explanation:

The Pressure can be calculated using the formula:

P = F/A

Where;

F = force (N)

A = Area (m²)

Based on the information provided in the question, F = 30N, A = 0.06m²

P = F/A

P = 30/0.06

P = 500N/m²
