How does molecule size affect melting point?
Intermolecular forces increase as molecular size increases, thus the bigger the molecular size, the bigger the molecular mass, the stronger the intermolecular forces, the more energy required to break the bonds between the molecule, thus a higher melting/boling point.
How adding water affects viscosity?
it increases mass in same volume, therefore density(viscosity) increases =)
How does force affects mass and acceleration?
Increasing force increases acceleration but increasing mass decreases acceleration.
How is molecular mass and vapour density related?
density is mass per unit volume, meaning that as mass increases ,the density increases. Unlike volume, as it increases the density decreases.
How does changing force and mass affects acceleration?
Increasing force increases acceleration but increasing mass decreases acceleration.
How does the mass diffusivity of a gas mixture changes with temperature and pressure?
mass diffusivity increases with increasing temperature and decreases as pressure increases.
How does increasing mass effects kinetic energy?
Increasing mass increases kinetic energy. The formula for KE = 1/2mv2, where m is mass in kg and v is velocity in m/s. KE is directly proportional to both mass and velocity, so if either one increases, so does the KE.
Relationship between gas's molecular weight and speed of effusion?
Higher is the molecular mass lower is the rate of effusion, when mass increases by 4 times rate decreases to one half (Graham's law of diffusion).
How could density be used to determine the mass of particular volume of a substance?
In a set volume of any substance increasing the density increases its mass

As the molecular mass of a nonpolar liquids increase the boiling points does what?
If the mass increases with the volume (ie if the density remains the same) then the boiling point remains constant. If the volume remains contstant with rising mass (ie greater density) then the boiling point increases.
Difference between cleavage and mitotic cell division?
mitosis is a division of nuucleus while cleavageis the division of cytoplasm and cleavage increases the number of cellswithout increasing mass and mitosis increasing mass as well as numbers.
