Answer:
7 K.
12. 6 °F
Explanation:
Convert the individual temperatures to Kelvin (Surface temperature and internal temperature) before calculating the temperature difference of the body,
Let The Surface temperature Be = X °C
And the internal Temperature will be = (X + 7) °C
Converting the surface and the internal temperature to temperature in Kelvin
Surface Temperature of the body (K) = (X + 273) K
Internal Temperature of the body (K) = (X + 7) + 273 = (X + 280) K.
∴ Temperature difference of the body (K) = Internal temperature(K) - surface temperature(K) = (X + 279) - (X + 280)
= X - X + 280 - 273 = 7 K.
∴Temperature difference of the body (K) = 7 K
Also for Fahrenheit, Convert the individual temperatures (Surface temperature and internal temperature) to Fahrenheit before calculating the temperature difference of the body.
We use , F = 1.8C + 32
Where C = temperature in Celsius.
also,
Let The Surface temperature Be = X °C
And the internal Temperature of the body will be = (X + 7) °C
Converting to Fahrenheit
Surface Temperature of the body = 1.8X + 32 °F
Internal Temperature of the body = 1.8(X+7) + 32 = 1.8X + 12.6 + 32
Internal Temperature of the body = 1.8X + 44.6 °F
∴ The temperature difference of the body (°F) = Internal temperature(°F) - surface temperature(°F) = (1.8X + 44.6) - (1.8X + 32)
surface temperature(°F) = 1.8X - 1.8X + 44.6 - 32
surface temperature(°F) = 12. 6 °F.
