As temperature increase pressure remaining constant the half life of a radioactive element?

Answer 1

In general, and at temperatures one might commonly find on Earth, temperature has no appreciable effect on half life. If the temperature of an atom is elevated sufficiently, we can get effects in which the question of half life becomes moot, because the atom is no longer able to hold together in atomic form, but I am supposing that is not what this question is about.

There are certain circumstances, under which the half life might be affected by temperatures that a person might consider more ordinary. One such place is in a neutron rich environment, such as in the core of a nuclear reactor. Neutrons colliding with the nuclei of atoms can cause the atom to become a different isotope of the same element, to decay, or to undergo fission. The probability of the neutron colliding with the nucleus depends on what is called the "nuclear cross section" which is measured in a unit called a "barn." The nuclear cross section generally increases with temperature, though as the temperature increases, the actual value goes up and down, depending on the temperature and the specific isotope involved.

So, in a neutron rich environment, increasing the temperature generally reduces the half life.

Answer 2

Increases. An increase in temperature typically increases the rate of chemical reactions, including radioactive decay. This means that at higher temperatures, the rate of decay of a radioactive element will be faster, resulting in a shorter half-life.

Answer 3

it stays the same temperature, and pressure do not affect the half life of an radioactive element :D glad i can help :D

Answer 4

Nothing. The halflife of a substance is simply a property specifying its rate of decay, it doesn't do anything.

Answer 5

Halflife is a constant for any given isotope. It does not change with time.

Answer 6

The temperature has any importance in this case.

Answer 7

The temperature does not affect the half-life.
