## What is the function of glass beads in a fractionating column?

The fractionating column is packed with glass beads. It provides a large surface area for vaporization and condensation of the liquid mixture.

## Why are glass beads used in this experiment?

The purpose of the beads is to ensure that each respirometer is uniform in volume. The vial with glass beads alone will permit detection of any changes in volume due to atmospheric pressure changes or temperature changes.

## How much are glass beads?

Bead kits. Bulk glass bead kits that have premium color patterns (usually four or more swathes or stripes of color per bead) cost anywhere from \$16.95 to \$20 per pack of 120-140 pieces.

## Why is simple fractionating column packed with glass beads?

Fractionating Column:

A simple fractionating colunrn is a tube packed with glass beads. The beads provide surface for the vapours to cool and condense repeatedly.

## Why do non-germinating peas consume less oxygen?

The non-germinating peas shows hardly any consumption of oxygen. Since the germinating peas are germinating or sprouting, they require a more extensive amount of energy or ATP. … Therefore, the non-germinating peas have a significantly low rate of respiration in comparison with the germinating peas.

## What is your hypothesis for this experiment cellular respiration?

HYPOTHESES: The experimental hypothesis is that germinating seeds will show a greater rate of respiration than control glass beads. Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.

## Are non-germinating seeds dead?

Non-germinating seeds, however, are dormant and use very little respiration. Some respiration must occur in order for the seed to live. The rate of cellular respiration will be greater in germinating peas than in dry peas, and temperature will have a direct effect on this rate.

## What are glass beads made of?

Glass beads are made of silica and other minerals melted at a high temperature to form a thick, viscous liquid. The liquid is molded into the desired shape and hardens as it cools.

## What is glass beading?

Glass beading uses tiny lead-free glass beads made of soda lime glass to provide an aesthetic treatment on stainless steel surfaces. Glass is one of the largest blasting medias used in abrasive blasting, more commonly known as sandblasting.

## What are an alcohol are easily separated by distillation because of their?

water and alcohol are easily separated by distillation because of their different densities, different colours, different boiling points, different melting points.
