How does temperature affects the atmospheric pressure of a place?
Temperature: When the temperature of a place increases, the atmospheric pressure decreases. This happens because an increase in the temperature results in the heating of the air. Warm air expands. The molecules of the warm air become less dense and hence exert less pressure.
What is the effect of temperature on the velocity?
Thus for Fahrenheit temperatures (TF), Tk = 273 + 5/9(TF – 32). In a cold medium molecules move more slowly and this reduces the velocity at which sound is transmitted….Effect of Temperature on V sound in air.
| Temperature (deg. C) | Velocity of Sound in Air (m/sec) |
|---|---|
| 20 | 344 |
| 21 | 345 |
| 100 | 386 |
What is speed of sound in air?
about 761 mph
What is the speed of sound in air at 37 C?
| Temperature of air ϑ in °C | Speed of sound c in m/s | Density of air ρ in kg/m3 |
|---|---|---|
| +35 | 351.96 | 1.1455 |
| +30 | 349.08 | 1.1644 |
| +25 | 346.18 | 1.1839 |
| +20 | 343.26 | 1
What is the speed of sound in air of temperature 25 degrees Celsius?346.4 What happens to resistance if temperature increases? As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thus when temperature goes up, resistance goes up. For some materials, resistivity is a linear function of temperature. The resistivity of a conductor increases with temperature. Why do parts of my body feel hot?There are many potential reasons that your skin may feel hot to the touch. These can include an elevated body temperature or an increase in blood flow near the surface of the skin. Common causes of these things can be fever, skin reactions, or environmental conditions.
