the optmum temperature in storing ice cream is between -20°F and -10°F.(a) What is this temperature range in degrees Celsius?(b) How about in kelvin?
Answer (1)
The answer is: Celsius — –28.89°C to –23.33°C Kelvin — 244.26 K to 249.82 K (a) To CelsiusFormula: °C = (°F – 32) × 5/920°F = (–20 – 32) × 5/9 = –52 × 5/9 ≈ –28.89°C10°F = (–10 – 32) × 5/9 = –42 × 5/9 ≈ –23.33°C(b) To KelvinFormula: K = °C + 273.1528.89°C + 273.15 ≈ 244.26 K23.33°C + 273.15 ≈ 249.82 K
