The final temperature of the sample of gas is 689.65 Kelvin.
<h3>What is the relation between temperature and pressure?</h3>
Relation between the temperature and pressure will be represented by the ideal gas equation PV = nRT, and for this question required equation is:
P₁/T₁ = P₂/T₂, where
P₁ & T₁ are the pressure and temperature of the initial sample.
P₂ & T₂ are the pressure and temperature of the final sample.
Pressure is in mmHg and on putting values from the question on the above equation, we get
T₂ = (810)(390.8) / (760) = 416.5 degree C = 689.65K
Hence required temperature of the sample is 689.65K.

The only cause we know of that could shift the spectrum of a source toward longer wavelengths isthe source moving away from us. That's how we interpret the red shift when we see it, and that's where the whole idea of the expanding universe comes from. But ... just like gravity and the Earth going around the sun ... it can't be proved, so it's "only a theory".
Answer:
1.50 × 10²⁴ atoms C
Explanation:
Step 1: Define
Molar mass of C - 12.01 g/mol
Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Step 2: Use Dimensional Analysis
= 1.50375 × 10²⁴ atoms C
Step 3: Simplify
We are given 3 sig figs.
1.50375 × 10²⁴ atoms C ≈ 1.50 × 10²⁴ atoms C

a) Natural selection will work negatively against rabbits that only eat berries as the drought is preventing berries from growing. It wont have any negative impact on rabbits that only eat grass as the grass is still surviving.
b) The statement ‘population has variations’ is backed up by the fact that the rabbits eat different things. They aren’t all the same. The statement ‘some variations are favorable’ is backed up by the fact that the rabbits that only eat grass are able to survive the drought. Their variation in eating grass instead of berries let’s them live. The statement ‘a population will change over time’ is backed up by the fact that the rabbits that only eat berries will die out. This will not only change the size of the population but going forward will create a population that has more rabbits that eat only grass on account of natural selection.
