A sample of oxygen gas occupies a volume of 7.93 L at 59 Β°C and 843 mm Hg. The volume of the gas sample increases to 8.96 L while its pressure increases to 1.13 x 10^3 mm Hg. If the ideal gas law is obeyed, the temperature of the gas sample at the new volume and pressure is _____ Β°C.
The Gaussian distribution also known as the Normal distribution, is given by the following
equation:
π¦(π₯) = ππ₯π β(π₯βπ)^2/2π^2
where parameter π is the mean and π the standard deviation.
(i) Write a MATLAB code to create a 1000 point Gaussian distribution of random numbers
having π = 0 and π = 1. (20)
(ii) Plot this distribution. (10)
A. A sample of helium gas at a pressure of 0.774 atm and a temperature of 259 Β°C, occupies a volume of 512 mL. If the gas is heated at constant pressure until itβs volume is 745 mL, the temperature of the gas sample will be _______ Β°C.
B. A sample of krypton gas at a pressure of 964 mm Hg and a temperature of 38 Β°C, occupies a volume of 13.8 liters. If the gas is cooled at constant pressure to a temperature of 8Β°C, the volume of the gas sample will be ______ L.
2.) An asset costing P50,000 has a life expectancy of 6 years and an estimated salvage value of P8,000. Calculate the depreciation charge at the end of the fourth period using fixed-percentage method.
B. A sample of neon gas at a pressure of 0.996 atm and a temperature of 28.9 Β°C, occupies a volume of 18.5 liters. If the gas is allowed to expand at constant temperature to a volume of 25.7 liters, the pressure of the gas sample will be ______ atm.
