Approximate Value Of Room Temperature

Human comfort can extend beyond this range depending on humidity air circulation and other factors.

Approximate value of room temperature.

In certain fields like science and engineering and within a particular context room temperature can mean different agreed. Room temperature electrical resistivity versus composition for copper zinc alloys. Room temperature ranges from 15 25c 59 77f only approximately so to 2 dp at normal pressure and room temperature 20 deg c the mass is 0 998 207 1 grams only approximately so to 2 dp at. Colloquially room temperature is the range of air temperatures that most people prefer for indoor settings which feel comfortable when wearing typical indoor clothing.

The speed of sound through air is approximately 343 m s at normal room temperature which is at 20 c. People tend to accept a slightly higher room temperature in the summer and lower value in the winter based on the clothing they would wear outdoors. Rho i ac i 1 c i. Rho is the mass per unit volume of earth s atmosphere air density like air pressure decreases with increasing altitude.

It also changes with variation in atmospheric pressure temperature and humidity at 1013 25 hpa abs and 15 c air has a density of approximately 1 225 kg m or 0 00237 slug ft about 1 1000th that of. The lower the density that of a medium the faster the speed of sound and the higher the compressibility is the slower the sound travels. The density of air or atmospheric density denoted ρ greek.
