Answer:
42.24 psi.
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 29.72 psi
Initial volume (V₁) = 10.22 L
Final volume (V₂) = 7.19 L
Final pressure (P₂) =?
The final pressure can be obtained by applying the Boyle's law equation as follow:
P₁V₁ = P₂V₂
29.72 × 10.22 = P₂ × 7.19
303.7384 = P₂ × 7.19
Divide both side by 7.19
P₂ = 303.7384 / 7.19
P₂ = 42.24 psi
Therefore, the final pressure is 42.24 psi
Answer:
Generally, a solid changes into liquid and then into gas state.
But the process of transistion of solid directly into gas without passing throuhg the intetmidiate stage, liquid is called sublimation.
Some of uses of sublimation are:
- Sublimation helps to dry substance within getting moist. This process of sublimation is also beneficial in medicine.
- Piriciple of sublimation is used in air freshener solids used in room and toilets.
- Dry ice is the solid form CO2 gas whose sublimation is used as cooling agent and storing dead bodied.
- Camphor, a substance used in houseold sublimes to give a pleasant smell inside the house.
