Question

What are the steps to calibrating a thermometer using the ice-point method?

Answer 1

The steps to calibrating a thermometer using the ice-point method are: placing ice in a beaker, measuring and recording the temperature of the ice, measuring and recording the temperature every minute until after the ice has melted, plotting a graph of time versus temperature, heating water in a beaker and measuring its temperature, and finally measuring the temperature of the water as it cools.

Step-by-step explanation:

1. Place some ice in a beaker.
2. Measure the temperature of the ice and record it.
3. After 1 minute measure the temperature again and record it. Repeat every minute, until at least 3 minutes after the ice has melted.
4. Plot a graph of time versus temperature for the heating of ice.
5. Heat some water in a beaker until it boils. Measure and record the temperature of the water.
6. Remove the water from the heat and measure the temperature every 1 minute, until the beaker is cool to touch.

Answer 2

Answer: Put the thermometer stem or probe into the ice water. Make sure the sensing area is under water. Wait 30 seconds or until the reading stays steady. Adjust the thermometer so it reads 32˚F (0˚C).
