✔✔c (0.075 lb/ft3) - ✔✔Under standard conditions, air weighs approximately ____ lb/ft3.

a. 0.055 lb/ft3
b. 0.065 lb/ft3

, ✔✔d (86°) - ✔✔Solve to find the Fahrenheit temperature corresponding to 30°C.
a. 32°
b. 68°
c. 70°
d. 86°

Note: 32°F = 0°C. 9/5°F = 1°C.

°F = (9/5 x °C) + 32
°C = (°F - 32) x 5/9

✔✔b (68°) - ✔✔Solve to find the Fahrenheit temperature corresponding to 20°C.
a. 32°
b. 68°
c. 70°
d. 86°

Note: 32°F = 0°C. 9/5°F = 1°C.

°F = (9/5 x °C) + 32
°C = (°F - 32) x 5/9

✔✔d (26.7°C) - ✔✔Solve to find the Celsius temperature corresponding to 80°F.
a. -1.1°C
b. 0.0°C
c. 15.6°C
d. 26.7°C

Note: 32°F = 0°C. 9/5°F = 1°C.

°F = (9/5 x °C) + 32
°C = (°F - 32) x 5/9

✔✔c (15.6°C) - ✔✔Solve to find the Celsius temperature corresponding to 60°F.
a. -1.1°C
b. 0.0°C
c. 15.6°C
d. 26.7°C

Note: 32°F = 0°C. 9/5°F = 1°C.

°F = (9/5 x °C) + 32
°C = (°F - 32) x 5/9
