Answer:
Volume of the helium will be 1.0L
Explanation:
To understand this question it is necessary to talk about 2 laws:
Charles's law that states: The volume of a given amount of gas held at constant pressure is directly proportional to absolute temperature.
Boyle's law that states: The volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
Now, in the problem, if you have 4.0L of helium:
If the temperature is halved and the volume varies directly with temperature (Charles's law), the volume of helium will be 2.0L
Then, the pressure es doubled and as volume varies inversely with pressure (Boyle's law), the volume of helium will be halved, being 1.0L.
Thus, <em>volume of the helium will be 1.0L</em>
Answer:
I think it would be Scientific Method.
A nonmetal and a nonmetal will make molecular compounds like H2O and CO2
Answer:
"Kinetic energy of the gas is more as compared to that of the liquids. But when compare it to the solid, kinetic energy of liquid is more."
Explanation:
a) Relatively high density : This happens as a result of the tight or packed or can be say close arrangement of the particles.
b) Ability to diffuse : As we know that in gases the constant and the random motion of the particles of the liquid leads to diffusion. But it is very slow as compared to the gases and also porque liquid particles are close together.
c) Ability to evaporate:This happens as a result of the molecules of the liquid having different kinetic energies with particles having higher than that of the average energies that move faster.
Bromine attracts electrons more strongly. Cesium is In fact the least electro negative element.
Sodium is more likely to lose an electron because is is less electro negative. Strong electronegativity make the element want more electrons. Sodium has loose electrons with a lower electronegativity so it gives it up easier.
