Volumen = constant => P/T = constant

T1 = 21°C + 273.15 = 294.15 k
P1 = 0.82 atm

T2 = - 3.5°C + 273.15 = 269.65 k
P2 = ?

P2 / 269.65k = 0.82atm / 294.15k

P2 = [0.82atm / 294.15k] * 269.65kg = 0.75 atm

Which of the following statements about the formation of a solution is true?
bekas [8.4K]

<span>In the formation of a solution, energy is required to overcome the forces of attraction between the solvent particles. The first step is for the solvent particles to move in order for solute particles to enter the system. This process is endothermic where energy flows into the system. The second step is when solute particles must separate from other solute particles. Lastly, the solute should move between solvent particles.</span>
