Final answer:
Use a meat thermometer to determine the temperature of a steak on a grill. The recommended internal temperatures for different levels of doneness are: Rare: 125°F, Medium Rare: 135°F, Medium: 145°F, Medium Well: 150°F, Well Done: 160°F.
Step-by-step explanation:
To determine the temperature of a steak on a grill, you should use a meat thermometer. A meat thermometer will provide the most accurate reading of the internal temperature of the steak. Insert the thermometer into the thickest part of the steak without touching the bone, and wait for the reading to stabilize. The recommended internal temperature for a steak varies depending on the desired level of doneness:
- Rare: 125°F (51.7°C)
- Medium Rare: 135°F (57.2°C)
- Medium: 145°F (62.8°C)
- Medium Well: 150°F (65.6°C)
- Well Done: 160°F (71.1°C)
