Similarly, a liquid at saturation pressure and temperature will tend to flash into its vapor phase as system pressure is decreased. There are two conventions regarding the standard boiling point of water. The normal boiling point is 99.7 C ( 211.99 F) at a pressure of 1 atm (i.e., 101.325 kPa). Hope this helps! :-)

A particular forest is 10,000 acres. Determine its size in hectares. (1 hectare = 2.47
igor_vitrenko [27]

Taking into account the change of units, a particular forest is 4,048.58 hectares.

<h3>Definition of rule of three</h3>

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷ a

The direct rule of three is the rule applied in this case where there is a change of units.

<h3>Size in hectareas</h3>

To perform in this case the conversion of units, you must first know that 1 hectare = 2.47 acres.

So, the rule of three can be used as follow: if 2.47 acres is 1 hectare, 10,000 acres equals how many hectares?

2.47 acres ⇒ 1 hectare

10,000 acres ⇒ x

So: x= (10,000 acres ×1 hectare)÷ 2.47 acres

Solving:

<u><em>x= 4,048.58 hetares</em></u>

In summary, a particular forest is 4,048.58 hectares.

Pls 50 points right answer gets brainliest
GuDViN [60]

Answer:

thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)

heat is the thermal energy that flows from one substance to another due to a temperature difference.

Thermal energy is measured in temperature change.

Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).

conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.

convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.

radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.

What makes balancing redox reactions different from balancing other reactions?
sergejj [24]

Redox reactions are those <u>chemical reactions that involve the transfer of electrons between reactants</u>, altering the <em>oxidation state</em> of their elements.

In this type of reactions an element releases electrons that another element accepts, so there is a net transfer of charge.

When balancing redox reactions, not only must the chemical elements in the reactants and products be equalized (by the <em>law of conservation of the mass</em>), but also the charged that is transferred in the process must be balanced, since <u>the electrons that are lost in oxidation are the same as those that are gained in reduction (</u><em>law of conservation of charge:</em> <em>there is no destruction or net creation of electric charge</em>).
