- Need help, please. Suppose you have 8.4 L of an ideal gas at 25 °C initially in a container equipped with a piston. You arrange to keep the pressure on the gas equal to 2 atm as you compress the gas to a volume of 2 L. How much work does it take to compress the gas?Q20: Dr. Fahrrad has been riding his bike to his job and is curious how many ATP his body is breaking apart in order to do the work required to get to his job. Dr. Fahrrad rides 8.6 kilometers to his job, has a mass of 68.4 kilograms and has an average acceleration of 2.4 kilometers per second squared. The molecule ATP is able to do work, measured in kilojoules per mole of ATP broken into ADP. The SI unit for work is a joule. Using the information given we can calculate work and then convert to moles of ATP. The first step is to take stock of what we are given in the word problem and what we are trying to find. We have mass, distance, and average acceleration. We are trying to find how many ATP are required to power the bike ride to work. The equation for work, is force times distance and will tell us how many joules Dr. Farrhad is using on his bike ride. It also incorporates one of our given variables, distance. However, the distance was reported in kilometers and the SI unit of…In an engine, an almost ideal gas is compressed adiabatically to half its volume. In doing so, 2710 J of work is done on the gas.
