What are the main sources of error in enthalpy experiments?
What are the main sources of error in enthalpy experiments? Sources of error Likely sources of experimental error in this experiment include improper mixing, the placement of the thermometer bulb onto slowly dissolving solids, incorrect reading of the thermometer, not enough thermometer readings, and spillages. The most probable sources of error are the first two. […]
