Hypothesis: How will molecular size affect the rate of evaporation and how will this correlate
Simora [160]

A molecular size affects the rate of evaporation when the larger the intermolecular forces in a compound, the slower the evaporation rate and this correlates with temperature change.

Molecular size seems to have an effect on evaporation rates in that the larger a molecule gets or grows from a base chemical formula, its evaporation rate will get slower.

<h3>What is the molecular size?</h3>

This is a measure of the area a molecule occupies in three-dimensional space as this relates to the physical size of an individual molecule.

Hence, we can see that a molecular size affects the rate of evaporation the larger the forces, the lower the rate.

♔♔Can water stay liquid below zero degrees Celsius?✞♡♡♡​
astra-53 [7]

Answer:

Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of water drops below zero degrees Celsius as you apply pressure. When we apply pressure to a liquid, we force the molecules to get closer together.

Enzymes are described as catalysts, which means that they __________. View Available Hint(s) Enzymes are described as catalysts,
givi [52]

Answer:

increase the rate of a reaction without being consumed by the reaction

Explanation:

  • Enzymes are biochemical catalysts that increase the rate of chemical reactions.
  • They increase the rate of a chemical reaction without being consumed by the reaction.
  • Enzymes increase the rate of chemical reactions by decreasing the activation energy of the reactants.
  • Catalysts such as enzymes do not affect the free energy change of a chemical reaction (delta G). Therefore, delta G for a catalyzed and non-catalyzed reaction is equal.
