Mole - one of the most important concepts in chemistry - is a kind of link to go from the microworld of atoms and molecules in a normal macrocosm grams and kilograms.
In chemistry often have to consider large numbers of atoms and molecules. For fast and efficient calculation made using the weighing method. But it is necessary to know the weight of individual atoms and molecules. In order to identify the molecular weight must be added the weight of all atoms in the compound.

The definition of potential energy is the energy that is absorbed within an object. The object is holding but not using the energy. In contrast, kinetic energy is the energy of motion so whenever something is moving it has kinetic energy.

The most classic example of going from potential to kinetic energy is the idea of a roller coaster. Once the roller coaster is going up towards a hill, it’s building up in potential energy. Once the coaster comes to the top of the hill, it contains total potential energy. And while the coaster begins to come down and pick up speed, this potential energy is being transferred as kinetic energy.

Hope that helps! :)

A balloon is floating around outside your window. The temperature outside is 31 ∘C , and the air pressure is 0.700 atm . Your ne
DochEvi [55]

Answer:

the volume of gas inside this balloon = 146.3 L

Explanation:

Given that:

The temperature T = 31 °C = ( 31 + 273.15 )K = 304.15 K

The air pressure P = 0.700 atm

number of moles of gas n = 4.10 moles

Gas constant = 0.0821 L atm/K/mol

The objective is to calculate the volume of the gas inside the ballon.

Using the Ideal gas equation

PV = nRT

V = nRT/P

V = (4.10×0.0821×304.15)/0.700

V = 102.3799/0.700

V = 146.257 L

V = 146.3 L

Thus, the volume of gas inside this balloon = 146.3 L
