A person would have a different weight on each planet. Arrange the planets in increasing order based on a person’s weight on the
2 answers:
Answer: Mercury<Uranus<Earth<Neptune
Explanation: Weight is the downward force acting on an object due to gravity.
w= weight of an object
m= mass of object
g= gravity
As the person has a constant mass, the weight differs due to the value of gravity (g). The planet having highest gravity would make a person weigh the most.
As the value of gravity varies: Mercury (3.7)<Uranus(8.9)<Earth(9.8)<neptune(11.2), the weight of the person varies in the same order: Mercury<Uranus<Earth<neptune.

Answer:
The equation it's very simple and corresponds to the ideal gas model, which is this one:
Explanation:
Gases tend to behave following the mathematic relationship due to the ideal gas formula shown above; where <em>P</em><em> </em>is the pressure applied to a gas inside a recipient (for example), <em>V</em> is the volume of the recipient where the gas exists (that is the same volume of the gas since any gas tends to fill all the volume of a limited space of the recipient), <em>n</em> is the number of moles and indicates the amount of gas (molecules of gas) inside the recipient and <em>T</em> is the temperature of that particular gas. <em>R</em> is just a constant called <em>the gas constant </em>(). An ideal gas doesn't lose its internal energy over time, so the collision between the particles of the gas are considered <em>perfect elastic collisions</em>; which means that the system gas-recipient is a <em>closed physical system</em> that won't release energy to the surroundings,
Getting back to the actual question after the background: as <em>n </em>and<em> R </em>are constant, the <em>pressure </em>and <em>temperature</em> are directly correlated to each other, consider we assume <em>V </em>can't change; when the <em>T</em> drops, so does the <em>pressure </em>(think of it as the gas contracts itself because is losing excitation from the source of <em>temperature</em>). In other hand, if <em>T</em> increases, the gas will tend to expand itself so it will also increase the <em>pressure</em> (the gas is now colliding a lot inside the recipient because is gaining energy from the source of <em>temperature</em>)
