C. Convert the ff. temperature

1. 30.5°C to k =

2. 91.3°F to °C

3. 515.3k to °C =

4.-273°C to F =

1. To convert Celsius to Kelvin, you simply add 273.15. So, 30.5°C is equal to 30.5 + 273.15 = 303.65 K.

2. To convert Fahrenheit to Celsius, you can use the conversion formula: °C = (°F - 32) / 1.8. So, 91.3°F is equal to (91.3 - 32) / 1.8 = 32.83 °C.

3. To convert Kelvin to Celsius, you simply subtract 273.15. So, 515.3 K is equal to 515.3 - 273.15 = 242.15 °C.

4. To convert Celsius to Fahrenheit, you can use the conversion formula: °F = (°C × 1.8) + 32. So, -273°C is equal to (-273 × 1.8) + 32 = -459.4 °F.
