It is none of the three. Conduction occurs when a heat source directly is touching an object. 

Explanation: Number 1 is convection. Key term: convection currents. Number 2 is radiation, as radiation can pass through space. Number 3 is just explaining a part of the convection current.

Explain what a chemical reaction is and moles
Delvig [45]

Answer:

A process during which chemical bonds between atoms are broken and new ones are formed, producing one or more substances.

Moles are the amount of substance that contains as many particles.

Explanation:

A chemical reaction is when a chemical change occurs for example when a nail comes into contact with air and is then exposed to air it begins to rust. It forms a red-brown substance which changes the chemical composition of the original compound.

Examples of chemical reactions:

Combustion

Oxidation (rusting)

Cooking an egg

Photosynthesis

Digestion

Fireworks

Paper Burnin

The mole is the amount of substance that contains as many particles (molecules, ions or atoms) as there are in 12g of carbon.

1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12 and that number is referred to as Avogardo's constant (6.022 x 10^{23}).

What happens when energy is added to each state?
e-lub [12.9K]

Answer:

One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules. ... The temperature at which a substance goes from a solid to a liquid is it melting point.

What is the maximum vertical distance between the line y = x 2 and the parabola y = x2 for −1 ≤ x ≤ 2?
Mrac [35]

x2=x+2 at x=−1 and x=2 so we have no need to worry about the end-points

f(x)=x+2−x^2

df/dx=1–2x

and that is zero (indicating a maximum) at x=1/2

So the maximum distance is f(1/2)=2.5–0.25=2.25

Which forces are intramolecular and which intermolecular?
sergiy2304 [10]

There must be an intramolecular force. The oxygen atoms are produced as a result of the breakdown of oxygen molecules. Intramolecular force is necessary to stop the oxygen (O2) in the air from changing into the O atom.

Which force causes attraction between O2 molecules?

The result is the London dispersion force, a fleeting attractive attraction, which is created when the electrons in two neighboring atoms occupy positions that temporarily cause the atoms to form dipoles. This interaction is commonly described by the phrase "induced dipole-induced dipole attraction".

What is the difference between intramolecular forces and intermolecular forces which type is stronger?

In general, intramolecular forces are greater than intermolecular forces. Ion-dipole interaction exerts the strongest intermolecular force, followed by hydrogen bonds, dipole-dipole interaction, and London dispersion. Examples. Hydrogen bonding forces, London dispersion forces, and dipole-dipole forces are the three different kinds of intermolecular interactions. The three different kinds of intramolecular forces are metal bonds, ionic bonds, and covalent bonds.
