How do you use contour lines?
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
Why don't they see hydrogen Balmer lines in the spectra of stars with temperatures of 3200 K?
These stars are so cool that nearly all of the hydrogen atoms are in the ground state. The visible-light Balmer absorption lines of hydrogen are produced by electrons moving from the 1st excited state to a higher orbit. However in M class stars most of the hydrogen is in the ground state, and absorption from the the ground state occurs at ultraviolet wavelengths.
What do Each of the colored lines in hydrogen's emission spectrum corresponds with?
transition of an electron from a higher energy level to a lower energy level.
When the pink colored light of glowing hydrogen passes through a prism what colors can you see?
Hydrogen breaks down into four colors. Violet at 410 nm, blued/violet at 434 nm blue/green at 464.4 nm and red of 656.2 nm.
Breaks between plates are known as what?
fault lines
On a map what do black lines between the states usually represent?
On maps, black lines between states represent boundaries or borders, where one state stops and the others starts. These are also called state lines.
Why the distances between the lines for the hydrogen spectrum decreases with the decrease in wavelength?
Just one line for hydrogen.
How does whater form hydrogen bonds?
Water, H2O, is a polar molecule in which the larger, more electronegative oxygen atom develops a partial negative charge, and the smaller, less electronegative hydrogen atoms develop a partial positive charge. The slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule. This weak attraction is called a hydrogen bond. Click on the related link for an illustration of the polar water molecule and hydrogen bonding between water molecules. The dashed lines represent the hydrogen bonds and the δ- represents a partial negative charge, and δ+ represents a partial positive charge.
What do the lines in a formula represent?
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.
What does H -- O -- H represnt?
H-O-H represents the line structure of water, where the lines represents the covalent bonds between the hydrogen and oxygen.Water consists of two hydrogens and one oxygen but it will have to be rearranged to HOH for how the molecule actually bonds together. Since hydrogen only has one valence electron, it can only have one bond with another atom. Oxygen has two so it can bond with two hydrogens.However, this line structure does not show the two lone pairs on the oxygen so the actual shape of water is an angular (bent) shape with a bond angle of ~104.5 degrees
What might the lines between the footprints of two of the organisms represent?
a tail
What do black lines between the states usually represent?
State boarder
On a map what do the lines between the states usually represent?
state border.
What do the lines on phase diagram represent?
equilibrium between two states
What do lines represent in a structural formula?
The lines in a structural formula represent the chemical bonds. These bonds are attractive forces between atoms that allow the formation of chemical substances.

What does the lines on the phase diagram represent?
This line is a boundary between two phases.
