Answer:
1st one is right..it helps filter waste inside the cell.
Because the pot isn’t water it just gets really hot and you can burn yourself if you touch it
<u>Answer:</u> The moles of oxygen and carbon dioxide in air is and respectively
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of atmosphere =
Average molar mass of atmosphere = 28.96 g/mol
Putting values in above equation, we get:
We know that:
Percent of oxygen in air = 21 %
Percent of carbon dioxide in air = 0.0415 %
Moles of oxygen in air =
Moles of carbon dioxide in air =
Hence, the moles of oxygen and carbon dioxide in air is and respectively
When heated, particles vibrate faster, thus increasing the distance between one another. The distance between these particles results in changes of state. Therefore, increased molecular motion results in expansion of an object. This works vice versa for cooling. As the vibrations slow down, the particles become closer together. This results in contraction.
