Sentences with phrase «trapped air bubbles by»

I was wondering if the combination of increased pressure and aging has been proven not to affect the CO2 content of the trapped air bubbles by somehow hiding CO2.

Not exact matches

In this case, the egg proteins are denatured by whipping, join together and trap air bubbles.

Without the stretchy gluten to trap the air bubbles released by the yeast, you wouldn't get a nice, light loaf.

Krypton is produced by cosmic rays bombarding Earth and then stored in air bubbles trapped within Antarctic ice.

Scientists can determine ancient atmospheric concentrations by measuring CO2 and methane levels in tiny air bubbles trapped in such ice, formed when the ice fell to the earth as snow.

Confirmation of this idea requires a direct record of the ancient atmosphere — and this can be recovered by analysing the air that became trapped in tiny bubbles within ice as the snow it formed from fell to Earth.

It strongly binds the ingredients in the bread dough together, which causes them to be trapped, gluten also stretches around the trapped bubbles of air which is produced by yeast.

When whipped, those proteins unfold and bond together, trapping the air bubbles created by the whisk.

These measurements, supplemented by analyses of air bubbles trapped in ice core samples, show unequivocally that atmospheric CO2 has increased from a pre-industrial level of 277 ppm in 1750 to present day concentrations that are approaching 390 ppm.

Hints that warming is being caused by emissions from industry and other human activities have been extracted from air bubbles trapped in ancient ice, from variations in tree rings, from the quick retreat of alpine glaciers.

The paper, «Reconstruction of past atmospheric CO2 concentrations by ice core analysis», acknowledges that, due to impurities, liquid water can exist as low as -50 deg C. Diffusion of CO2 into this water, due to its far higher solubility than nitrogen and oxygen, will partially deplete the CO2 from trapped air bubbles.

The ice contains minute bubbles of prehistoric air trapped when it was formed, and once a reliable method had been developed by which to isolate and analyse that air (it is done in a vacuum), it was possible to get an idea of the composition of the atmosphere of the past, through ice - ages and interglacials.

The knowledge, for example, that funnel web spiders can fall into swimming pools and survive for up to 24 hours by trapping air bubbles on hairs around their abdomen haunts me.
