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).
The heat sentry feature activates when the exhaust temperature reaches 200Â°F (93Â°C) and deactivates when the exhaust temperature decreases to 185Â°F (85Â°C). If the ventilation hood is turned off and the heat sentry sense 200Â°F exhaust, the blower automatically turns on. Once the exhaust temperature decreases to 185Â°F the blower turns off. If the ventilation hood is turned on to low speed and the heat sentry senses 200Â°F exhaust, the blower increases to high speed.
