Answer:
1.48L
Explanation:
From the question given, we obtained the following data:
V1 (initial volume) = 2.50L
T1 (initial temperature) = 308K
P1 (initial pressure) = 1.15atm
P2 (final pressure) = 1.80atm
T2 (final temperature) = 286K
V2 (final volume) =..?
Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the gas can obtain as follow:
P1V1/T1 = P2V2/T2
1.15 x 2.5/308 = 1.8 x V2/286
Cross multiply to express in linear form:
308 x 1.8 x V2 = 1.15 x 2.5 x 286
Divide both side by 308 x 1.8
V2 = (1.15 x 2.5 x 286)/(308 x 1.8)
V2 = 1.48L
Therefore, the new volume of the gas is 1.48L
<span>An example of a homologous structure is the forelimb of a whale, a human, and a dog.
Homologous structures have the same structure, but may have a different function.
Homologous structures indicate a common ancestor.
A homologous structure is an organ or bone that's in common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor. This is in contrast to analogous structures where two unrelated animals have structures with similar forms or functions due to convergent evolution. With that in mind, let's look at the available options and see what fits.
An example of a homologous structure is the wing of a bird and an insect.
* This is an example of an analogous structure, so this is a bad choice.
An example of a homologous structure is the forelimb of a whale, a human, and a dog.
* Exactly. This is a good example of a homologous structure, so this is a good choice.
Homologous structures have the same function but a different structure.
* False. This is a type of analogous structure.
Homologous structures have the same structure, but may have a different function.
* True. A homologous structure is a structure that was present in a common ancestor of different animals. Further evolution may have caused those animals to diverge and the common structure may now be used for different purposes. So this is a good choice.
Homologous structures indicate a common ancestor.
* Yes, by definition.
Homologous structures do not indicate a common ancestor.
* Since the previous option was true, this must be false, so a bad choice.</span>
