As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
Also give you a 10, the last one looks really nice
Answer:
liquid at room temperature
mercury is an exception to that though
Answer:
m Br = 439.472 g
Explanation:
mass Br = ?
∴ mol Br = 5.50 mol
∴ molar mass Br 79.904 g/mol
mass = (mol)*(g/mol)
⇒ m Br = (5.50 mol)*(79.904 g/mol)
⇒ m Br = 439.472 g
