The term sublimation is used to describe the conversion of a solid directly to a gas, without passing through the liquid state. This process is an endothermic process which means that it needs a supply of energy to happen. It happens at a temperature and pressure that is below the triple point of a substance. There are some substances that prefers sublimation rather than evaporation like arsenic and carbon. This is for the reason that the pressure for the triple point of these substances are very high and it would be difficult for them to be at the liquid state. The energy needed for sublimation to happen is calculated from the sum of enthalpy of vaporization and enthalpy of fusion.
Potassium, aluminum, silicon, magnesium neon
Answer:
The volume is
<h2>180 mL</h2>
Explanation:
In order to solve for the volume we use the formula for Boyle's law which is
<h3>
</h3>
where
P1 is the initial pressure
V1 is the initial volume
P2 is the final pressure
V2 is the final volume
Since we are finding the final volume we are finding V2
Making V2 the subject we have
<h3>
</h3>
From the question
P1 = 300 mmHg
V1 = 300 mL
P2 = 500 mmHg
Substitute the values into the above formula and solve for the final volume obtained
That's
<h3>
</h3>
We have the final answer as
<h3>180 mL</h3>
Hope this helps you
Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.
