Answer:
a. increase
Explanation:
Based on the kinetic molecular theory of gases, the average kinetic energy of the system will increase.
- The average kinetic energy is heat
- If temperature increases, heat of a system will also rise.
- According the kinetic molecular theory "the temperature of the gas is a measure of the average kinetic energy of the molecules"
Therefore, due to the increase in temperature, the average kinetic energy of the system increases.
Assuming that the space within the solid or liquid is vacuum, it is not matter because there is no mass inside. However, there is a volume. The volume inside a solid would have regular straight sides because atoms of a solid is compactly arranged. For liquids, the space could be irregular curves and paths because the atoms in a liquid are free-flowing.
Temperature is a measure of the average kinetic energy of the particles in a substance.
Answer:
10.304 kPa
Explanation:
n=mol nitrogen (N2) gas=2moles
Temperature=T=310 K
Volume=0.5 L=0.5 dm3
R=8.31 J K−1 mol−1
From Gerenal gas equation we know that
PV=nRT
P=nRT/V
Putting the values
P=(2*8.31*3100/(0.5)
P=10.304 kPa
or P=10304 Pa
Answer:
Because of its weak intermolecular forces.
Explanation:
Hello there!
In this case, according to the given description, it turns out possible for us to recall the chemical structures of both ethanol and dimethyl ether as follows:
Thus, we can see that ethanol have London dispersion forces (C-C bonds), dipole-dipole forces (C-O bonds) and also hydrogen bonds (O-H bonds) which make ethanol a liquid due to the strong hydrogen bonds. On the other hand, we can see that dimethyl ether has just London and dipole forces, which are by far weaker than hydrogen bonding, that makes it unstable when liquid and therefore it tends to vaporize quite readily.
Regards!
