Sagot :

Does stirring affect the rate of solution?

  • Breaking a solute into smaller pieces increases its surface area and increases its rate of solution. Stirring -- With liquid and solid solutes, stirring brings fresh portions of the solvent in contact with the solute. Stirring, therefore, allows the solute to dissolve faster.

Null Hypothesis:

  • The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.

Alternative Hypothesis

  • In statistical hypothesis testing, the alternative hypothesis is a position that states something is happening, a new theory is preferred instead of an old one (null hypothesis). ... In statistics, alternative hypothesis is often denoted as Ha or H1. Hypotheses are formulated to compare in a statistical hypothesis test.
