Because the atoms are separating bc of the heat. A solid has really compact atoms so if it was melted its atoms would become looser and form a liquid
Divide the grams by 25 to 195 then times it in decimal
Answer:
a, b, c Flask B
Explanation:
The root mean square velocity of a gas is given by
V = √ ( 3RT/M)
where m is the molar mass, T is the temperature of the gas and R is the gas constant.
Therefore we have that the the velocity of the gas molecules is inversely proportional to the square root of the molar mass . That is the heavier the molecules the slower they will move which makes sense and the lower its kinetic energy.
The greater the velocity the more collisions the gas will have against the walls of the container.
The molar mass of CO and N2 are 28 g/mol while H2 is 2 g/mol. Hence hydrogen the lightest will have a greater kinetic enrgy, the greatest root mean square velocity and the greatest number of collisions with the wall of the container.
Notice that the pressure given for each is of the gases is different being the greatest for CO but pressure does not have an effect on the kinetic enery of the molecules.
The precise fit on the ring stand. The ability to hold more substance than a test tube. A shallow bottom to increase the surface area of a liquid, leaving the solid behind.
I know for a fact the answer would (not) be the last option. This would not be a way that electricity would be able to really flow.
Your correct answer would be of when the
"e<span>
lectrons flow from the negative end of a source towards the positive end."This would be because when the electrons would be free, they would have enough energy to then move from the negative side of the end, to the positive side.</span>
