Answer:
1. Why was the line of best fit method used to determine the experimental value of absolute zero?
The line of best fit method is used to determine the experimental value, because it most accurately shows where the line crosses the x-axis.
2. Which gas law is this experiment investigating? How does your graph represent the gas law under investigation?
This investigation is experimenting the “Ideal Gas Law”. This law by Gay-Lussac shows that when the volume in a container of a gas is held constant, while the temperature is increased, the pressure will also increase.
3. Using your knowledge of the kinetic molecular theory of gases, describe the relationship between volume and temperature of an ideal gas. Explain how this is reflected in your lab data.
As temperature increases, volume increases when pressure is held constant. As seen in the chart, as the temperature increases the volume in each gas also increases slightly.
4. Pressure and number of moles remained constant during this experiment. If you wanted to test one of these variables in a future experiment, how would you use your knowledge of gas laws to set up the investigation?
Supposedly at a constant temperature, the gas volume and pressure stay constant. Therefore, the amount of moles also remains constant. So perhaps, the temperature could fluctuate, meaning it will not only increase or decrease, but do both. This will avoid consistency and prove the Ideal Gas Law to be true.
Explanation:
Many elements show very strong similarities to each other.<span>For example, lithium (Li), sodium (Na), and potassium (K) are all soft, very reactive metals.

Answer:
C. it causes freezing point depression which requires the gasoline to reach a much lower temperature before freezing
Answer:
A. begin with hydrogen; pair a metal with a hydroxide ion
Explanation:
Acid can be distinguished from base on the basis of formulas in such a way that acid formula start with hydrogen.
For example:
Hydrochloric acid is strong acid. Its formula is HCl.
It start with hydrogen
Sulfuric acid is acid. Its formula is H₂SO₄
it is also start with hydrogen.
Base:
Base is distinguish from acid in such a way that in base formula metal is pair with hydroxide ion.
For example:
Sodium hydroxide is base. Its formula is NaOH.
sodium is metal while OH is hydroxide ion.
Potassium hydroxide is base. its formula is KOH.
potassium is metal and OH is hydroxide ion.
