Question

6.

A gas occupies a volume of 224 cm and a pressure of 1.51 bars. If the gas expands to a volume of 578 cm,
what will the new pressure be? (Assume the temperature remains constant.)

Answer 1

The new pressure is 0.5852 bar

Step-by-step explanation:

Since the temperature is constant, we can apply Boyle's Law.

Boyle's Law states that at constant temperature, pV = constant

`p_(1)V_(1)=p_(2)V_(2)\\p_(1)=1.51\:bar\\V_(1)=224cm^(2)\\V_(2)=578cm^(2)\\Let\:p_(2)\:be\:the\:new\:pressure.\\p_(2)=(p_(1)V_(1))/(V_(2))=(1.51*224)/(578)\\ p_(2)=0.5852\:bar`

Therefore, the new pressure is 0.5852 bar
