k22: Variation Functions and Multipling and Dividing Rational Expressions Question 4: 10 pts The pressure P of a gas varies directly with the temperature T and inversely with the volume V. A certain gas has a volume of 6 liters (L), a temperature of 400 Kelvins (K), and a pressure of 2.4 atmospheres (atm). If the gas is expanded to a volume of 15 L and is heated to 650 K what will the new pressure be? 3.69 atm 0.56 atm 0.0008 atm 1.56 atm Question 5: 10 pts The time iaken for a journey on a motorway vares inversely as the average speed for the

Explanation / Answer

P = k T / V

2.4 = k ( 400 ) / 6

k = 2.4 * 6 / 400

k = 0.036

P = .036 * 650 / 15

P = 1.56 atm

4th option is correct
