1–30E

1–30E Consider a system whose temperature is 18°C.
Express this temperature in R, K, and °F.
ANS
1-30EA temperature isgiven in °C.Itistobe expressed in °F, K, and R.
Analysis Using the conversion relations between the various temperature scales,
T(K]= T(°C)+ 273 = 18°C+ 273 = 291 K
T(°F] = 1.8T(°C)+ 32 = (1.8)(18) + 32 = 64.4°F
T(R]= T(°F) + 460 = 64.4 + 460 = 524.4 R
