Ответ:
Therefore the density of water is about 1000 kg/m³.
1 atm pressure is 101325 Pa.
g = 9.8 m/s²
The height of a water column, h, needed to measure 1 atm is given by
(1000 kg/m³)*(9.8 m/s²)*(h m) = 101325 Pa
h = 1013225/9800 = 10.3393 m = 1033.93 cm
10.339 m or 1033.9 cm
Ответ:
35 Celsius
Explanation:in this situation the difference in temperature is larger resulting in faster rate of transfer
