If you have enough liquid helium, it might smother the fire or cool the combusting materials that are supporting the fire so much that they are below their kindling temperature. However, this would be a very impractical fire fighting technique compared with using solid or liquid carbon dioxide, because carbon dioxide gas is denser than air while helium gas is much less dense than air. Furthermore, liquid helium is expensive and only rarely if ever available when one needs to fight a fire!
Note that the boiling point of helium is 4.22 K, −268.93 °C, −452.07 °F. From a practical standpoint it would be nearly impossible to maintain such extreme cryogenic conditions anywhere in the vicinity of a fire!
There is no word equation, except that helium will exist as liquid phase in liquid helium
Yes, liquid helium is a true substance. It is the liquid form of the element helium, which is a noble gas. At very low temperatures close to absolute zero, helium gas condenses to form liquid helium, exhibiting unique physical properties and behaviors.
what is the density of helium at room temperature?
Yes, liquid helium boiling is a physical property. Boiling point is a physical property that describes the temperature at which a substance changes from a liquid to a gas. In the case of helium, its boiling point is very low at -268.9 degrees Celsius.
Helium turns into liquid at the lowest temperature, approximately -268.9 degrees Celsius.

no, it's a constant explosion by gases known as helium, hydrogen. it is a fire, not a liquid.
In theory you could fight a fire with cryogenic helium, but in reality it would be exceedingly impractical and expensive. While helium is not extremely expensive, it is quite a bit more expensive than other substances normally used to fight fires - and much less plentiful. It is very expensive to lower helium to cryogenic conditions and the equipment necessary to maintain it at cryogenic conditions is also very expensive to build and operate. Note also that because it is such a light gas, it would quickly rise away from the fire, so it would require a lot more of it to fight the fire than if something heavier were used - like water, powder, or foam.
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.

Liquid helium is a lot colder than liquid nitrogen.
all fires are toxic more or less. foam is generally used to fight liquid fuel fires as they form a blanket of air bubbles that prevents vapour from the liquid to mix with the oxygen present in the fire area.
There is no such thing as "conducting fire." Helium is not flammable, if that's what you mean.
Liquid helium in the helium I phase boils at about 5 K, lower than any other substance. (Liquid helium in the helium II phase does not boil, it simply evaporates. Helium is truly weird stuff at very low temperatures.)
The boiling point of liquid helium is -268.9 degrees Celsius.
