The volume of a gas is increased from 445mL to 515ml. If the initial pressure was 120kPa, what is the final pressure of the gas?

103.7 kPa

Explanation:

Given that:

initial volume of gas V1 = 445ml

initial pressure of gas P1 = 120 kPa.

new Volume V2 = 515ml

new pressure P2 = ?

Since, only pressure and volume are involved, apply the formula for Boyle's law

P1V1 = P2V2

120 kPa x 445ml = P2 x 515 kPa

53400 = P2 x 515 kPa

P2 = 53400/515

P2 = 103.7 kPa

Thus, the final pressure of the gas is 103.7 kPa

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
