On a cold winter day, the temperature is 10.5°C, what is this temperature in °F? 1. 2. 3. What would be the volume in liters of 320 g of oil if the density of the oil is 0.8 g/ 4, Convert 6.5 meters to inches ( 1 inch = 2.54 cm)

Answer 1

1 j = 0.239 calories 100j = 23.9 calories 2) T(degree F) = 9/5 T(degree C) + 32 T(degree F) = 9/5 (10.5 degree) + 32 T(degree F) = 50.9 degree F Volume = mass/Density Volume = 320 g/ 0.8 g/mL = 320 g/0.8 8/10^-3L = 320 g/ 0.8 times 10^3 g/L = 0.4 Liter 2.54 cm = 1 inch 1 cm = 1/2.54 inch 1 times 10^-2 m = 1/ 2.54 inch 1 m = 100/2.54 inch 6.5 m = 6.5 times 100/2.54 inch = 255.9 inch
