If the partial pressure of oxygen in a scuba air tank is 73.44 atm, the partial pressure of nitrogen is 128.52 atm, and the part
Ksenya-84 [330]
To answer this, we use Raoult's Law where the partial pressure is equal to the product of the fraction of the gas in the mixture and its total pressure. Also, we use Dalton's Law of Partial Pressure where the total pressure is equal to the sum of the partial pressure of the gases in the mixture.

Ptotal = 73.44 + 128.52 + 2.04 = 204 atm

201.96 = x (204)
x = 0.99

How are phase changes related to kinetic energy? Justify your response in two or more complete sentences.
mars1129 [50]
Energy is required to change the phase of a material, with the change in energy either it decreases or increases.
When the phase is changed, the temperature and kinetic energy does not change it stays the same but the internal energy changes.
Internal energy is the sum of chemical potential energy and kinetic energy of the molecules, and when the internal energy changes during a phase change it means average potential energy is changing.
