Friction because smooth ice provides very little resistance against objects, like ice skates being dragged across its surface.
Answer : The mass of helium added to cylinder were, 4.50 grams.
Explanation :
According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,
or,
As we know that:
As the gas is same that is helium gas. So the molar mass will be same.
Thus the formula will be:
where,
= initial volume of gas = 2.00 L
= final volume of gas = 4.50 L
= initial mass of gas = 2.00 g
= final mass of gas = ?
Now we put all the given values in this formula, we get
Therefore, the mass of helium added to cylinder were, 4.50 grams.
Answer:
Intraspecific competition examples,
Interspecific competition examples,
and what causes it to happen. <em>Skip to the bottom for shortest answer.</em>
- Intraspecific competition is for instance, when two cows of the same species compete for grass, the food source.
- Interspecific competition is for example, when a bear and another species compete for fish.
But why does this happen? ↓
This competition happens because of limiting factors in the ecosystem, and general competition. Animals compete for their food because they need this food to survive. If they do not compete for the food, the other animal will get the food and the opposing animal will be left hungry. These are the main reasons why animals will compete for their resources.
In conclusion,
In a short sum, competition happens because animals need food, and when they can't get food, they compete.
