Answer:
The final volume is 1.1 L.
Explanation:
Given data:
Initial pressure of gas = 125 KPa
Final pressure of gas = 375 KPa
Initial volume = 3.3 L
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
125 Kpa × 3.3 L = 375 Kpa × V₂
V₂ = 412.5 KPa. L/375 Kpa
V₂ = 1.1 L
The volume of gas is reduced to the 1.1 L because of increasing pressure.
Answer is: <span>Mutations sometimes improve the chances of survival for a plant.
</span>Mutations are very important because they change <span>variability in populations and in that way enable evolutionary change.
</span>There are three types of mutations:
1) good or advantageous mutations - <span> improve the chances of survival for a plant.
2) </span>bad or deleterious - decrease the chances of survival for a plant.
3) neutral - not affect he chances of survival for a plant.
-delta H symbolises an exothermic reaction. Hence, it gives off heat. Reversely, it would absorb heat.

<u>When the zebra eats grass, it gets energy from the sun that has been stored in the grass. Similarly, the lion obtains energy stored in the zebra. The zebra and lion both obtain the sun's energy indirectly from the energy that the grass obtained through photosynthesis. </u>
