If the temperature rises from 20°C to 25°C, how many degrees has it risen?

If the temperature rises from 20°C to 25°C, how many degrees has it risen?

• A. 3 degrees
• B. 4 degrees
• C. 5 degrees
• D. 6 degrees

Answer: (C)

The question asks for the change in temperature when it rises from 20°C to 25°C. To find the increase in temperature, you can simply subtract the starting temperature from the final temperature. So, you take the final temperature (25°C) and subtract the initial temperature (20°C): 25°C - 20°C = 5°C This calculation shows that the temperature has risen by 5 degrees. Therefore, it is clear that the correct answer is the one that states the temperature increase is 5 degrees. This understanding is crucial for solving similar problems involving temperature changes, where simple subtraction of two temperatures will give you the change in degrees.
