Final answer:
To find the final temperature in Fahrenheit after increasing a sample's temperature by 43.3 degrees Celsius, convert the increase to Fahrenheit and add it to the initial temperature. The final temperature is 173.14 °F when the increase is added to the initial 63.2 °F.
Step-by-step explanation:
If you work in a materials testing lab and are required to increase the temperature of a sample by 43.3 degrees Celsius, but have a thermometer that reads in degrees Fahrenheit, you need to convert the increase to Fahrenheit before adding it to the initial temperature. To convert the increase, use the formula °F = (°C × 9/5) + 32. First, find the Fahrenheit increase (°F) by substituting °C with 43.3 degrees Celsius, which is °F = (43.3 × 9/5) + 32 = 109.94 °F. Then add this to the initial temperature of the sample, 63.2 °F.
Therefore, the final temperature of the sample in Fahrenheit is 63.2 °F + 109.94 °F = 173.14 °F.
