<h2>The Pressure Increases
</h2>
Explanation:
- When the water is heated from 10℃ to 90℃ the pressure at the bottom of the beaker will also increase.
- For a closed system with liquid contents that is water, the pressure will always increase with a rise in temperature.
By using the formula;
where,
V1 & V2 are the volumes at the initial level and final level, both the volumes are the same(ignoring pressure distention), T1 & T2 are the temperatures and P1 & P2 are the pressures.
Therefore, we get the pressure excluding the volumes as -
-
Hence, according to the above explanation, if the temperature of the water increases then the pressure at the bottom of the beaker is also increased.
Answer:
52.28g
Explanation:
Given:
Mass of CO₂ = 71.89g
Solution:
The equation of the reaction:
CO₂ → C + O₂
We want to determine the mass of O₂ that will form from this reaction.
To do this, find the number of moles of CO₂:
Number of moles of CO₂ = 
Molar mass of CO₂ = 12+ 2(16) = 44g/mol
Number of moles of CO₂ = 
= 1.63mole
From the equation of the reaction:
1mole of CO₂ will produce 1 mole of O₂
So 1.63 mole of CO₂ also produces 1.63mole of O₂
The mass of O₂:
Mass of O₂ = number of moles of O₂ x molar mass of O₂
Molar mass of O₂ = 2 x 16 = 32g/mol
Mass of O₂ = 1.63 x 32 = 52.28g
Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals. Chemical rocks are classified mainly by the composition of minerals in the rock.

The answer is D because I don't see how energy is being converted by looking at yourself in the mirror.
Answer:
325mg of Aspririn
Explanation:
First you should note the information that the problem gives you:
- The bottle of Aspirin has 5gr (grains)
- 1gr(grain) = 65mg (miligrams)
Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:
-First you should put the quantity you need to convert:
-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:
-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:
-Finally you multiply numerators and divide by denominators:
