Answer:
18 degrees
Step-by-step explanation:
Assuming our initial temperature in Fahrenheit is 32 (Celsius would be 0)
If we increase by 10 degrees Celsius :F= 32 + 1.8(10)F= 32 + 18The final temperature would be 50 degrees F (Celsius 10), but there would have been an increase of 18 degrees F for the 10 degree change in C
