Question

The temperature of a system drops by 30°F during a cooling process. Express this drop in temperature in K, R, and °C.

Answer 1

272.05 K; 489.69 °R; -1.11 °C

Step-by-step explanation:

Fahrenheit can be converted to degrees Celsius using the following formula:

°C = 5/9 x (°F - 32) = -1.11 °C

The temperature in Kelvin is calculated from the temperature in degrees Celsius as follows:

K = °C + 273.15 = 272.05 K

The temperature on the Rankine scale is calculated from Kelvin as follows:

°R = 1.8K = 1.8(272.05) = 489.69 °R
