Question

Given a container of carbon dioxide gas with an initial volume of 14 L and pressure of 38 Pa, calculate the pressure if the volume is increased by 26 L. ​

Answer 1

Answer:

108.57 Pa

Explanation:

new volume of gas = 14 + 26 = 40 Lit

given

14 lit gas gives pressure = 38Pa

so 1 lit gas will give pressure = 38/14

therefore 40 lit gas will give pressure = (38×40) / 14

= 1520 / 14

= 108.57 Pa

Answer 2

13.3pa

Explanation:

we know that P1V1=P2V2

therfore 14x30=14+26xP2

P2= 14x30 ÷40 =13.3

therefore 13.3pa
