Question

Be sure to answer all parts. Convert: (a) 29.8°C (the melting point of gallium) to degrees Fahrenheit °F (b) 172.9°F (the boiling point of ethanol) to degrees Celsius °C (c) 4.2 K ,the boiling point of helium, to degrees Celsius °C

Answer 1

(a) 85.64°F

(b) 78.28°C

(c) - 268.8°C

Step-by-step explanation:

(a) 29.8°C into °F

To convert °C into °F, we use the formula given below

C / 100 = (F - 32) / 180

C / 5 = (F - 32) / 9

9 x 29.8 / 5 = F - 32

F = 85.64°F

(b) 172.9°F into °C

C / 5 = (F - 32) / 9

C = (172.9 - 32) x 5 / 9

C = 78.28°C

(c) 4.2 K into °C

C = K - 273

C = 4.2 - 273 = - 268.8°C
