To determine in which town dew would form on the grass, we need to compare the air temperatures recorded in each town with the dew point of 23.7 degrees Celsius. Dew typically forms when the air temperature drops to the dew point.
If the air temperature in a town is at or below 23.7 degrees Celsius, dew is likely to form. If the air temperature is above the dew point, dew will not form.
If you can provide the air temperatures for Arlington, Ashland, Salem, and Springfield, I can help you identify which town would expect dew to form.
