Homographs are words that are spelled the same regardless of pronunciation (they may be pronounced the same or differently). Homonyms are words that are both spelled and pronounced the same. Therefore a homonym is both a type of homograph and a type of homophone. To be correct I believe the Venn diagram should have one circle labeled homograph and the other labeled homophone. The intersection should be labeled homonym.
An Excessive Heat Warning is issued when heat indices are expected to reach at least 105 degrees, except at least 110 degrees over Delmarva and far southern New Jersey (Salem, Cumberland, Cape May, and Atlantic Counties).
Odor-causing bacteria live and thrive in warm. water and can infest the water heater. The problem. frequently can be corrected by returning the. thermostat to its recommended operating tempera-. ture (approximately 160 degrees F) for 8 hours. This will kill the bacteria. (Caution: Be sure the. water heater has an operable pressure relief valve. before increasing the temperature, and warn. occupants of the scalding hazard.) If a lower tem-. perature is preferred for routine operation, periodic. high temperature flushing can be used whenever. the odor returns.
