Convert each temperature.

a. 212 °F to °C (temperature of boiling water at sea level)

b. 22 °C to K (approximate room temperature)

c. 0.00 K to °F (coldest temperature possible, also known as absolute zero)

d. 2.735 K to °C (average temperature of the universe as measured from background black body radiation)

Solution 52E: (a) 0.105 in. to mm, Here, we have to convert inch to mm, by using some of the conversion factors. We know 1 m =100 cm 1 inch= 2.54 cm The conversion factors are 2.1 inm 100 cm 0.105 in. = 0.105 in x 2.54 cmx 1 m x 1000 mm 1 in 100 cm 1 m = 0.2667 x 10 mm = 2.67 mm Therefore, 0.105 in. is equal to 2.67 mm (b) 0.650 qt to mL, Here, we have to convert qt to L, by using some of the conversion factors. We know 1 qt =1.057 L 1 L =1000 mL The conversion factors are 1.057 L 1000 mL 1 qt 1L 0.650 qt = 0.650 qt x 1.057xL1000 mL 1 qt 1L = 687.0 mL Therefore, 0.650 qt. is equal to 687.0 mL (c) 8.75 pm/s to km/hr, Here, we have to convert pm/s to km/hr, by using some of the conversion factors. We know 1 pm = 10 -12m 1000 m =1 km 1 min= 60 s 1 h =60 min The conversion factors are 1012 m 1km 60s 60 min 1 m , 1000 m, 1 min 1h Thus, 8.75 pm/s = 8.75 pm/s x 1012 m x 1km x 60s x 60 min -13 1 m 1000 m 1 min 1h = 315 x 10 km/h -13 Therefore, 8.75 pm/s is equal to to 315 x 10 km/h (d) 1.955 m to yd 3 3 3 Here, we have to convert m to yd , by using some of the conversion factors. We know 1 m = 1.09361 yd The conversion factor is 1.09361 yd 1 m Thus, 3 3 1.09361 yd 3 1.955 m = 1.955 m x ( 1 m ) = 2.557 yd 3 Therefore, 1.955 m is equal to to 2.557 yd 3 e) $3.99/lb to dollars per kg, Here, we have to convert dollars per lb, to dollars per kg,, by using some of the conversion factors. We know 1 lb = 453.6 g 1000 g= 1kg The conversion factor are 1lb 1000g 453.6 g 1 kg Thus, $3.99/lb = 3.99 dollarx 1lb x 1000g lb 453.6 g 1 kg = 8.796 dollar/kg Therefore, $3.99/lb is equal to to 8.8 dollar/kg (f) 8.75 Ib/ft3 to g/ml . Here, we have to convert Ib/ft3, to /ml,, by using some of the conversion factors. We know 1 lb = 453.6 g 1000 g= 1kg 1 mile = 5280 ft 1 mile= 1.6093 km = 1.6093 x1000 m 1 km= 1000 m 1 m =100 cm 3 1 cm = 1mL The conversion factors are 453.6 g 5280ft 1mile 1 m 1 lb 1 mile 1.6093x 1000 m 100 cm Thus, 8.75 Ib/ft3 = 8.75 lb x 453.6 gx ( 5280ft ) x ( 1mile ) x ( 1 m ) ft3 1 lb 1 mile 1.6093x 1000 m 100 cm 14 15 3 = 5.84 x 10 g/4.83 x 10 cm = 1.209 x 10 g/cm 3 = 0.121 g/mL Therefore, 8.75 Ib/ft3 is equal to to 0.121 g/mL
