Question 5 1 pts The first law of thermodynamics states can be written as the following equation. AEint=Q+W To explore this physically, we use a gas that is containing in a piston + cylinder system. The cylinder holds the gas and the piston can compress the gas or expand the gas. Ax T T
To understand the many ways that heat can be added (subtracted) and work can be done on the gas (by the gas) we use a pressure versus volume diagram. Isotherms: lines of constant T pV diagrams PV = nRT pressure (Pa) isovolumetric heating isothermal expansion Wnet done by gas isothermal compression cooling isovolumetric Ap 1J= 1Pa.m³ AV Volume (m³) Which thermodynamic process matches how the first law variable that is zero.
Which thermodynamic process matches how the first law variable that is zero. isothermal process [ Choose ] adiabatic process Nr Choose change in internal energy the change in volume of the gas the change in temperature of the gas work done on the gas heat added to the gas the pressure of the gas isovolumetric process cyclic process [ Choose ]
