Hope that helps
It's describe as Ethylene
Answer:
hot air rises because gases expand as they heat up.When air heats up and expands,its density also increases.The warmer,less dense air effectively floats on top of the colder, dense air below it. This creates a buoyant force that causes warmer air to rise.
cold air sinks because it is heavier as its more dense ( because of closely packed molecules) soits harder for them to move and they absorb less energy. Also, gravity pulls on it more strongly.

Answer:
3. Judgement may be affected by what we already think is true (prior knowledge).
Explanation:
This statement is the correct answer because someone could be bias. Due to biases, prior knowledge may be incorrect and our conclusion may be wrong if you don't focus on the data given.
Le Chatelier's principle describes what happens to a system when something momentarily takes it away from equilibrium. If more reactant is added, the equation will shift to the right in order to make more product. If the temperature is decreased, the reaction will shift to the right to create more heat if it is exothermic (which will increase the product), and to the left if it is endothermic (which will decrease the products). <span> If the pressure is decreased, it will shift in the direction where there are more moles of gas present, because it can now take up more space.</span>
