At 96° F the saturation density of air is 0.04 kg/m3. If the weather report says the relative humidity is 81 % when the temperature is 96°F, the humidity is
[Provide your final answer up to 3 decimal places, e.g. 0.312]
(ii) If the temperature of any object is 83.12°F then calculate its value in °C
(a) – 18.88
(b) 28.4
(c) 271
(d) - 16.67
6) Use the 3 relations (equations) below to relate T(°F) to T(°C). Then, find out,
at what temperature a Fahrenheit and a Celcius thermometer would read the
same numerical value.
T(°R) = 1.8T(K)
T(°C) = T(K) – 273.15
T(©F) = T(°R) – 459.67
