Answer:
I just finished a unit on Scientific Method in my science class! Anyway, it's defined in the screenshots below. Hope this helps!
Answer:
A. The kinetic molecular theory relates the properties of a state of matter to the motion of its molecules.
Explanation:
The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.
Answer:
Aircraft cabins are therefore pressurized to maintained a similar pressure as that experienced at sea level to ensure normal breathing of passengers.
Explanation:
-Air becomes increasingly thinner with increasing altitudes.
-As such, oxygen becomes limited at higher altitudes and makes it difficult or almost impossible to breath a condition called hypoxia.
-Aircraft cabins are therefore pressurized to maintained a similar pressure as that experienced at sea level to ensure normal breathing of passengers.
The density of CO2 getting from experiment is 0.1/0.056 = 1.79 g/L. The percent error of this is (1.96 -1.79)/1.96*100%=8.67%. So the approximate percent error is 8.67%.
A molecular structure is a shape of a molecule, a three-dimensional shape or configuration of a molecule that is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more partners. Attached is the diagram for the molecular structure of So42
