What is gravitational potential energy

Gravitational potential energy is the potential energy an object has due to its position in a gravitational field. The higher an object is the greater its gravitational potential. When it falls the gravitational potential becomes kinetic energy.

Energy stored in height differences ~APEX

Does sugar affect the boiling point of water

Adding sugar to boiling water it will increase the boiling temperature very slightly

How many moles are in one molecule

The answer is that there are 6.0221415 x 1023 molecules in 1 mole. (not moles in a molecule)

How is molarity measured

In moles of substance dissolved in 1 L of water -Apex

Were JJ Thomson's ideas accepted by society at the time

yes jj thomsons ideas or beliefs were accpeted

Are alkali metal and alkaline earht metals similar

Alkali metals are slightly less reactive than earth metals

Another name for group of deer

Another name for a group of deer is a herd.

What is the force on the Moon's surface compared to the force of gravity on earths surface

The moon's gravity is about 1/6th of the earth's.

What property characterizes a spontaneous redox reaction

A positive sum of the two half-reactions' standard potentials

What information does the percent composition of an atom in a molecule give

The relative amount of mass an atom contributes to a molecule

What conditions will cause a redox reaction to be nonspontaneous

The sum of the voltages of the oxidatiin and reduction half-reactions is negative.

What was the atomic theory about

the structure of the atom

What effect does adding a solute have on the boiling point of a solution

Adding a solute to a solution, or some liquid, causes the boiling point to increase.

Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).

What shape is generated when the plane cuts the given solid in the manner shown

The following word describes the generated shape:

What are the biggest safety concerns related to walking surfaces

The biggest safety concerns relating to walking surfaces are probably the various conditions and defects that can result in slips, trips, and falls.

What did j.j Thomson experiment with

A cathode ray

Which molecular solid would have the highest melting point

A solid that has hydrogen bonding would melt the easiest.

What contribution to atomic theory resulted from Albert Einsteins work

a new model of the atom that describe electrons as being in a cloud
