In thermodynamics, work of a system at constant pressure conditions is equal to the product of the pressure and the change in volume. It is expressed as follows:
W = P(V2 - V1)
W = 1.3x10^5 (2x6 - 6 )
W = 780000 J
Hope this answers the question. Have a nice day.
Answer is: volume of methane is 78.4 mL.
n(CH₄) = 0.0035 mol.
At standard pressure and temperature:
V(CH₄) = n(CH₄) · Vm
V(CH₄) = 0.0035 mol · 22.4 L/mol.
V(CH₄) = 0.0784 L · 1000 mL/L = 78.4 mL.
Vm - molar volume.
Answer:
The device can collect up to 1.5 kg (3.3 lbs) of waste per day and holds a total of 20 kg (44 lbs) of waste. To illustrate this more vividly: A Seabin can collect up to 90’000 plastic bags, 37’500 coffee cups or 16’500 PET bottles per year.
