A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 90.1 kPa .The piston is now pulled up, expanding the gas, until the gas has a final volume of 49.0 L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.

18.4 kPa

Explanation:

Step 1: Given data

Initial volume of the cylinder (V₁): 10.0 LInitial pressure of the gas (P₁): 90.1 kPaFinal volume of the cylinder (V₂): 49.0 LFinal pressure of the gas (P₂): ?

Step 2: Calculate the final pressure of the gas

If we assume the gas behaves as an ideal gas, we can calculate its final volume using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁/V₂

P₂ = 90.1 kPa × 10.0 L/49.0 L

P₂ = 18.4 kPa

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
