When air is cooled its density
Answers
Answer:
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/m³ (0.001225 g/cm³ or 0.0765 lb/(cu ft), about 1/1000th that of water) according to ISA (International Standard Atmosphere).
Cold air is denser than warm air. The molecules are packed closer together. The amount of water vapor in the air also affects the density of the air. The more water vapor that is in the air, the less dense the air becomes.
As the temperature of air increases, its volume increases and its density decreases. ... As air is heated its density decreases because its mass remains constant but its volume increases. As air is cooled, its density increases because its mass remains constant but its volume decreases.
Explanation:
Answer:
As on cooling volume of air decreases and its mass remains constant so its density increases as Density =
volume/
mass
when air is cooled it's density increases.
