What are Laws of Thermodynamics? This concept comparison introduces Ss to the laws of the thermodynamics, pressure-volume diagrams for ideal gases, processes which are isothermal, isovolumetic, and adiabatic, and explains differences in enthropy and enthalpy. Through inquiry and exploration, students will describe how the law of conservation of energy dictates how heat energy is transferred through systems by convection, conduction, and radiation, its influences on changes of states of matter an
