Air is heated in a cylinder with a piston that keeps the pressure constant at 6 atm. The initial temperature of the gas, before heating, was 20°C, with an initial volume of the gas of 2 cubic metre. What is the heat (in kJ) that needs to be supplied to elevate the temperature of the gas to 100°C? The molecular weight of air is 28 g/mol. For air, cp (specific heat at constant pressure) = 1015 J/(kg. K) and cv (specific heat a constant volume) = 718 J/(kg. K). Hint: estimate the mass of the gas first. 1.13 kJ Your last answer was interpreted as

Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.
