Acook puts 1.90 g of water in a 2.00 l pressure cooker that is then warmed from the kitchen temperature of 20°c to 111°c. what is the pressure (in atm) inside the container?

P= 168258.30696 Pa

Explanation:

Given that

Mass of water vapor m = 19.00 g

Volume of water vapor V = 2.00 L

Temperature of water vapor is T = 111°C

                                                = 384K

Molar mass of water is M = 18.0148 g/mol

Number of moles are

n = m/M

= (1.90 g)/(18.0148 g/mol)

= 0.1054 mol

Pressure inside the container is

P= nRT/V

P= 168258.30696 Pa

it is called kinetic energy

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
