Water can "defy gravity" and climb uphill? True or false. Why or why not
harina [27]
The answer is actually <u>true</u><u>.</u>

The starting point of all rivers is higher than their end point. However, under the right conditions, small amounts of water can be drawn upwards, against the tug of gravity, through a phenomenon known as "capillary action". For this to occur, however, the water must be confined into a small flow space.

Hope this helps!  If it does, would you mind marking my answer as Brainliest? Thanks :D

How are energy inputs and outputs related to chemical reactions
GREYUIT [131]

The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.

The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.

From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.

The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.

As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.

It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.

A person is considered clinically dead if their blood circulation and breathing is stopped because those two is needed to sustain live. Notice that the diagnosis need both of them, so only one of them is not enough. Helga and John has no problem in breathing and circulation, so they wont be considered clinically dead.
