Answer:
A
Explanation:
a statement that can be tested through the scientific method
.15 km. It goes in this way from largest to least: Kilometers, Hectometers, decameters, meters, decimeters, centimeters, and finally millimeters. When you are going up in measures you move the decimal point one space to the left for each measure you pass. It is vice-versa for going down these measures plz mark brainliest.

Answer:
a)P/Po=0.263
b)γ=1.33 So gas is triatomic
c)
Explanation:
a)
initial pressure = Po
Initial volume = Vo
Final volume = 3.8 Vo
Lets take final pressure is P
we know that for free expansion process
PV= Constant
Po x Vo = P x 3.8 Vo
P=0.263 Po
So
P/Po=0.263
b)
Now gas is compressed in adiabatic manner
Final pressure = 1.56 Po
=1.56 Po
We know that for adiabatic process
γ=1.33 So gas is triatomic
c)
We know that average kinetic energy given as

Answer: 1) Boils</h3>
The less air pushing down on the water effectively allows the water to boil easier. Think of the water molecules as a bunch of marbles bouncing around in a box with a lid. The less air pressure means the lid is easier to open from the force exerted by the bouncing marbles, allowing those particles to escape and turn into gas.
So in short, if you are in the mountains, then it'll take less time to cook food because water comes to a boil faster.
