What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
What reactions are affected by particle size?
Particle size can affect various reactions such as dissolution rate, surface area available for reaction, and diffusion rates. Smaller particle sizes increase the surface area, leading to faster reactions, while larger particle sizes can reduce the reaction rate due to lower surface area available for reaction.
What is the solid particle formed in the mixture of milk and vinegar?
the solid mass are the proteins in the milk reacting with the acidic vinegar. Sour cream is made in the same way by adding lemon juice (acid) to heavy cream. The acid will react with the protein in the cream and thicken it.
How do you separate homogeneous mixtures?
Yes. Due to many factors. Evaporation, Particle sizes, and even color and shape.
How does the cooling rate of particles effect their size?
Faster cooling rates generally result in smaller particle sizes. Rapid cooling prevents particles from growing larger by minimizing the time available for crystal growth and agglomeration. Slower cooling rates can lead to larger particle sizes due to increased time for crystal growth and aggregation to occur.
