In an atomic model that includes a nucleus, the negative charge correlates to the electron and is located outside of the positively charged nucleus. It is found in a given region, where there is a probability of electrons to be found called the electron cloud.
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas
I’m assuming the top ruler has more measurement points, like more specific numbers. This would mean the top ruler is more reliable because you can be more specific with your measurements
The law which this chemist is most likely investigating heating a fixed amount of gas in a sealed glass container is: Gay Lussac’s law.
Gay Lussac's law states that when the volume of an ideal amount of gas is held (kept) constant, the pressure of the gas is directly proportional to the absolute (Kelvin) temperature of the gas.
Mathematically, Gay Lussac's law is calculated by using the formula;
<u>Where:</u>
is the original pressure.
is the final pressure.
is the original temperature.
is the final temperature.
In conclusion, the chemist is most likely investigating how changes in temperature affect the pressure of the gas by heating a fixed amount in a sealed glass container in accordance with Gay Lussac's law.
