Answer:
We will use ideal gas equation in this problem
PV = nRT
Where
P = pressure of gas or air = ?
V = volume of air = volume of pressure cooker = 5.68 L
T = temperature = 394 K
n = moles of air = 0.355
R = ideal gas equation = 0.0821 L atm / mol K
Putting values
Pressure = nRT / V = 0.355 X 0.0821 X 394 / 5.68 = 2.02 atm.
Answer :
(a) The dimensions in are,
(b) The distance in centimeters is, 40.64 cm
Explanation :
(a) The conversion used :
and,
As we are given the thickness, width, length dimensions in inches, inches and feet respectively.
Now we have to determine the thickness, width, length dimensions in centimeter, centimeter and meter respectively.
The dimensions in are,
(b) The conversion used :
As we are given the distance in inches. Now we have to determine the distance in centimeter.
The distance in centimeters is, 40.64 cm
