How many moles of n2 are in a flask with a volume of 250ml at a pressure of 300.0 kpa and a temp of 300.0 k

We assume that N2 is an ideal gas thus we use the ideal gas equation in order to solve for the number of moles of N2. The ideal gas equation is expressed as : PV = nRT. The calculations are as follows:

(300 x 10^3) Pa x (2.5 x 10^-4) mL = n x 8.314472 Pa.m3/(mol.K) x 300 K

n = 0.0300 mol N2

The dispersed phase is liquid and dispersed medium in milk is liquid

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
