Sentences with phrase «hydrogen nuclei into»

THE Sun generates huge amounts of energy by combining hydrogen nuclei into helium.

The most obvious example is a fusion reactor that has been running smoothly for more than 4 billion years: the sun, which fuses hundreds of millions of tons of hydrogen nuclei into helium every second.

Not exact matches

This theory assumes that the heavier elements have properties which can only actually result from a very rare process in the universe which makes several hydrogen nuclei fuse into heavier ones.

Pagels (1984) points out that if the relative masses of protons and neutrons were different by a small fraction of 1 per cent, making the proton heavier than the neutron, hydrogen atoms would be unstable since the protons that constitute their nuclei would spontaneously decay into neutrons.

With no nuclear fusion to sustain them, they collapse into Earth - size balls of tightly bound carbon and oxygen nuclei with an outer layer of hydrogen plasma (disrupted atoms).

Immense heat, pressure and magnetic fields ionise and contain the gas, turning it into a plasma in which hydrogen nuclei fuse to form helium nuclei, releasing energy.

Magnetized Linear inertial Fusion (MagLIF) combines powerful laser light with strong magnetic fields to fuse hydrogen atoms into helium nuclei.

Specifically, they measured hydrogen and its isotope, deuterium (hydrogen with an extra neutron in its nucleus) with ion microprobes, which use a focused beam of ions to sputter ions from a small rock sample into a mass spectrometer.

Comets are surrounded by a huge cloud of atomic hydrogen because water (H2O) vaporizes from the icy nucleus, and solar ultraviolet light breaks it apart into hydrogen and oxygen.

Their hope was that the neutrons shooting into the acetone would collide with the carbon and hydrogen nuclei, and this would create disturbances that would «seed» the bubbles produced by the sound waves.

When an antineutrino hits a proton — a hydrogen nucleus in a water molecule in the giant tank — it transforms that proton into a neutron and a positron.

The team used a novel technique that involves replacing the electrons in hydrogen atoms with negatively charged particles called muons, and then measuring subtle shifts in the energy that is required to bump a muon into a higher - energy orbit around the single - proton nucleus.

... the Sun and most other stars is the fusion of the lightest element, hydrogen, its nucleus having a single proton, into helium, the second lightest and second most abundant, with a nucleus consisting of two protons and two neutrons.

When a very massive star begins to run out of hydrogen and other nuclear fuels, it can collapse so suddenly that almost all its electrons are driven into nuclei.

Within the Sun's core, nuclear fusion reactions take place, with hydrogen nuclei being fused into helium nuclei.

«It takes tremendous amounts of energy for protons (hydrogen nuclei) to combine and change into neutrons.
