2. ### The temperature of one northeastern state range from 105F in the summer to -25F in the winter express this temp range in Celsius and kelvin?

C = (F - 32)/1.8 => C = (105 - 32)/1.8 ≈ 40.56 C = (-25 - 32)/1.8 ≈ -31.7 C = K - 273.15 => K = C + 273.15 K = 40.56 + 273.15 = 313.71 K = -31.7 + 273.15 = 241.45
