Answer:
Velocity = distance / time
if distance is same and time is 1/2
Velocity = distance / time/2
velocity = 2 (distance /time)
Velocity,= 2 * velocity
Velocity will be doubled
First, we need to assume acetylene to adapt an ideal gas behavior. So, we can use the Ideal Gas Law:
PV = nRT
Given:
V = 42 L
T = 305 K
P = 780 torr = 1.026 atm
R = gas constant, 0.0821 L atm/ mol K
n = amount of gas in the canister
1.026 atm * 42 L = n * 0.0821 L atm/mol K * 305 K
n = 1.72 moles of gas
Answer:
Have you ever seen a "shooting star" race across the sky at night? Shooting stars are meteors zooming at high speed through Earth's atmosphere and burning up along the way from friction. And right now is one of the best times to see them in person. The Perseids, which are impressive meteor showers that happen each year from mid-July to late August, have their peak activity around August 11 to 14. They're caused by Earth traveling through debris from the Comet Swift-Tuttle. Luckily, most meteors are tiny and burn up before hitting the ground. But if a meteor doesn't disintegrate, what's its impact on Earth? In this activity you'll explore how a meteorite’s size is related to the size of the crater it makes on impact.
Explanation:
The answer would be: C) Suspension
<span>Suspension- A mixture from which some of the particles settle out slowly upon standing.
-Heterogeneous
-Greater than 1000 nm in particle size
-Can be filtered
