The temperature difference between the inside and the outside of an automobile engine is 434 C°. Express this temperature difference on: a. The Fahrenheit scale.
b. The Kelvin scale.

434°C=813.2 °F

434°C=707.15 K

Explanation:

Fahrenheit is a temperature scale that sets the freezing point of water to 32 degrees Fahrenheit (° F) and the boiling point to 212 ° F (at normal atmospheric pressure). The conversion from degrees celsius to gradis fahrenheit is done by: ℉ = ℃ * 1.80+ 32.00

So, being 434°C: ℉ = 434℃ * 1.80+ 32.00= 813.2

Then: 434°C=813.2 °F

Kelvin is the temperature unit of the International System. It is one of the seven basic temperature units. Its symbol in the international system of units is K. Zero on the Celsius scale or degrees Celsius (0 ° C) is defined as the equivalent of 273.15 K. Then the conversion of Census degrees to Kelvin degrees is done by: K = ℃ + 273.15

Being 434 °C: K=434 °C+273.15=707.15

Then: 434°C=707.15 K
