Sensor data logging – graphing, smoothing, and calculating ΔH

ChemistryApplied & Practical ChemistryAges 15–16

A temperature sensor records a salt dissolving in water over time. Adjust the mass of salt, the sampling rate, and the sensor noise to see the computer plot the data, smooth it, find the extremum, and calculate the enthalpy of dissolution ΔH — following the standard procedure for IT-assisted chemistry practicals.
