Answer

a) 15°F in °C = -9.44 °C (b) 32.6°F in K = 273.48 K (c) 328 K in °F = 130.73 °F (d) 11.3°C in °F = 52.34 °F

Work Step by Step

Conversion: (a) 15°F in °C __°C = $\frac{(°F-32)}{1.8}$ __°C = $\frac{(15°F-32)}{1.8}$ -9.44 °C (b) 32.6°F in K First convert °F to °C ___°C =$\frac{°F-32}{1.8}$ __°C =$\frac{32.6°F-32}{1.8}$ 0.33 °C Then, convert °C to K ___K = °C +273.15 K ___K = 0.33°C +273.15 K 273.48 K (c) 328 K in °F First, convert K to °C ___°C = K - 273.15° ___°C = 328 - 273.15° 54.85 °C Then convert °C to °F °F = 1.8°C +32 __ °F = (1.8*(54.85°C) )+32 130.73 °F (d) 11.3°C in °F __ °F = 1.8°C +32 __ °F = (1.8*(11.3°C) )+32 52.34 °F
