ENERGY, WORK, AND HEAT ThermodynamicsENERGY, WORK, AND HEATHeat and work are the two ways in which energy can be transferred across theboundary of a system. One of the most important discoveries in thermodynamicswas that work could be converted into an equivalent amount of heat and that heatcould be converted into work.EO 1.8 DEFINE the following:a. Heatb. Latent heatc. Sensible heatd. Units used to measure heatEO 1.9 DEFINE the following thermodynamic properties:a. Specific enthalpyb. EntropyEnergyEnergy is defined as the capacity of a system to perform work or produce heat.PotentialEnergyPotential energy (PE) is defined as the energy of position. Using English system units, it isdefined by Equation 1-11.(1-11)PEmgzg_{c}where:PE = potential energy (ft-lbf)m = mass (lbm)z = height above some reference level (ft)g = acceleration due to gravity (ft/sec^{2})g_{c}= gravitational constant = 32.17 ft-lbm/lbf-sec^{2}HT-01 Page 14 Rev. 0
