how do i use a thermometer to find the change in a temperature?
To use a thermometer to find the change in temperature, follow these steps:
1. Start by checking the unit of measurement on the thermometer, such as Celsius (°C) or Fahrenheit (°F). Make sure you are comfortable with the unit being used.
2. Take note of the current temperature reading. This will be your starting point.
3. Measure the temperature again after a period of time or after the temperature has changed. This will be your second reading.
4. Subtract the initial temperature from the final temperature to find the change in temperature. If the final temperature is higher than the initial temperature, the change will be positive. If the final temperature is lower, the change will be negative.
For example, let's say the initial temperature reading is 25°C and the final temperature reading is 30°C. The change in temperature would be 30°C - 25°C = 5°C.
If you are looking for a more accurate change in temperature, it is important to minimize external factors that can influence the reading, such as direct sunlight, drafts, or holding the thermometer with your hands for an extended period before taking the second reading.
