Every time the refrigerator door is opened, some of the cold air inside escapes. The correct answer is "one-third" because it indicates that approximately 33% of the cold air can escape when the door is opened. This suggests that opening the door for a short period of time will result in a significant loss of cold air, making it important to keep the door closed to maintain the desired temperature inside the refrigerator.

One drop per second can add up to ____ gallons of hot water a month - that's more than one person uses in two weeks!
- A.
  
  145
- B.
  
  165
- C.
  
  120
- D.
  
  965
Correct Answer
B. 165

Explanation
If one drop per second adds up to 165 gallons of hot water a month, then that means in a month there are 60 seconds per minute, 60 minutes per hour, 24 hours per day, and approximately 30 days per month. So, 1 drop per second multiplied by 60 seconds per minute multiplied by 60 minutes per hour multiplied by 24 hours per day multiplied by 30 days per month equals 1,036,800 drops per month. Since 1 drop equals approximately 0.00003125 gallons, then 1,036,800 drops multiplied by 0.00003125 gallons per drop equals approximately 32.4 gallons per month. Therefore, the correct answer is 165 gallons.
