Calorimetry

Science / Chemistry / Calorimetry: Experimental determination of heat absorbed or released by a chemical or physical change.

Molality

Science / Chemistry / Molality: Concentration measured as moles of solute per kilogram of solvent. For example, a 1 m nacl solution contains 1 mole of nacl per kilogram of water. Molalities are preferred over molarities in experimen MORE

Enthalpy

Science / Chemistry / Enthalpy: Enthalpy (H) is defined so that changes in enthalpy (deltah) are equal to the heat absorbed or released by a process running at constant pressure. While changes in enthalpy can be measured using calor MORE

Internal Energy

Science / Chemistry / Internal Energy: Internal energy (U) is defined so that changes in internal energy (deltau) are equal to the heat absorbed or released by a process running at constant volume. While changes in internal energy can be m MORE
