please answer the following question.
Exercise 18.16 Part A Na Three moles of an ideal gas are in a rigid aubical bax with sides of length 0.240 m What is the force hat the gas exerts on each of the six sides ofthe box when thegastemperatur 20.0 07 Express your answer to three significant figures and include the appropriate units. F= Value Units Submit My Answers Give U Part B What is the force when the temperature of the gas is increased to 100.0 C Express your answer to three significant figures and include the appropriate units P-Value Units Submit My Answers Give Up

Explanation / Answer

n = 3

V = L^3 = 0.240^3 = 0.0138 m^3

(A) Applying ideal gas equation,

P V = n R T

P (0.0138) = (3) (8.314) (273 + 20)

P = 5.287 x 10^5 Pa

F = P A

F = (5.287 x 10^5)(0.240^2) = 30450 N

(B) P (0.0138) = (3)(8.314) (273 + 100)

P = 6.73 x 10^5 Pa

F = P L^2 = 38764 N
