c. Convert 298 K (room temperature)

- Celsius: [tex] 25^{\circ}C [/tex]
- Fahrenheit: [tex] 77^{\circ}F [/tex]

d. Convert 3680 K (the boiling point of tungsten)

- Celsius: [tex] 3407^{\circ}C [/tex]
- Fahrenheit: [tex] 6179^{\circ}F [/tex]

Answer :

Final answer:

To convert temperatures, subtract 273 to go from Kelvin (K) to Celsius (°C). Then, multiply by 9/5 and add 32 to go from Celsius (°C) to Fahrenheit (°F).

Explanation:

To convert temperatures from Kelvin (K) to Celsius (°C), subtract 273. To convert temperatures from Celsius (°C) to Fahrenheit (°F), multiply by 9/5 and add 32. To convert temperatures from Kelvin (K) to Fahrenheit (°F), first convert to Celsius (°C) and then use the Celsius to Fahrenheit conversion formula.

b. The boiling point of helium, 4 K:

°C = 4 K - 273 = -269°C

°F = (9/5)(-269) + 32 = -452°F
