π Isobaric process refers to a constant pressure on a PV graph where the y-axis remains unchanged.
π Increasing the volume of a gas can be achieved by heating it over a fire, causing the gas molecules to move faster.
π To counteract the higher speed of the gas molecules, the volume needs to be increased.
π In isobaric processes, pressure remains constant while volume changes.
π§ Instead of a flame, heat can be extracted from ice cubes to decrease volume.
π The equation for isobaric processes involves the change in internal energy and the constant pressure.
π Different types of processes in physics.
πΊπ¦ Change in volume affects pressure in a work equation.
π Isovolumetric process keeps volume constant.
π In a scenario without expansion or compression, no work is done.
π The equation for change in internal energy is 3/2 multiplied by the change in temperature.
π In an isothermal process, the pressure and volume are inversely proportional and shown as an inverse curve on a PV graph.
π Changing the temperature affects the graphs of pressure and volume.
π In processes with constant temperature, internal energy remains unchanged.
π Adiabatic processes involve no energy transfer.
π Inverse curves have constant pressure times volume.
π Volume is raised to the power of 5/3 in these processes.
β© Processes without flow of heat energy must occur quickly.
π₯ Adiabatic process involves expanding the gas quickly before heat transfer.
π Summary of what has been learned.
