Is endothermic chemical or physical
WebMar 28, 2024 · Anne Marie Helmenstine, Ph.D. Updated on March 28, 2024. The term "endothermic" describes a process which absorbs thermal (heat) energy. "Within heating" … WebCHEMICAL ENERGY is the energy stored in chemical bonding. Enthalpy, endothermic and exothermic reactions. To express the heat released or gained during chemical reaction or physical process (under constant pressure) the ENTHALPY (H) is used. Like U, H cannot be measured – only the change can be determined. ΔH = +/- HEAT/N
