The final temperature :T₂=411.125 K = 138.125 °C
<h3>Further explanation</h3>
Given
T₁=-20 °C+273 = 253 K
V₁=40 ml
V₂=65 ml
Required
Final temperature
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
T₂=(V₂.T₁)/V₁
T₂=(65.253)/40
T₂=411.125 K = 138.125 °C
the mass of a carbon atom is 1.994 x 10⁻²³ g
the mass of the carbon sample is 12.01 g
to find the number of Carbon atoms we have to divide the mass of sample by mass of a carbon atom.
number of C atoms =
therefore number of atoms = 6.023 X 10²³ atoms of carbon
<h2>The baking of a Pizza be Categorize as Endothermic Process</h2>
The baking of a pizza should be categorized as an endothermic process because the dough absorbs heat. An endothermic process is a method that absorbs energy from its surroundings which is habitually in the form of energy.
It can be a biochemical process like solving the salt in water or just the melting of ice. Therefore, the dough absorbs heat and it is categorized as an endothermic process.
