Final answer:
The change in temperature when the water needs to be heated from 67°F to 110°F is 43°F.
Step-by-step explanation:
To find the change in temperature, we need to subtract the initial temperature from the final temperature. In this case, the initial temperature is 67°F and the final temperature is 110°F. So, the change in temperature is 110°F - 67°F = 43°F.
