Ice in water at 0°C is strained and added to a room temperature, 50% ethanol in water mixture. Stirred with a temperature probe, the iced mixture reaches -2°C.
The stainless steel temperature probe is connected to a Vernier Labquest Mini and LoggerPro software displays a record of the temperature. Two probes can be used, one in the ice water, and one in the room temperature alcohol.
Instead of beakers, thick walled pint glasses are used. A strainer and bowl are needed for straining the ice from the water, showing that the same ice melting in water at 0°C melts in alcohol at -2°C. Energy into entropy.
