At 1.70 atm, a gas sample occupies 4.25 liters. If the pressure in the gas increases to 2.40 atm, what will the new volume be?
Answer:
3.01L
Explanation:
Given parameters:
Initial pressure, P1 = 1.7atm
Initial volume, V1 = 4.25L
Final pressure, P2 = 2.4atm
Unknown:
Final or new volume, V2 = ?
Solution:
To solve this problem, we use Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
P1 V1 = P2 V2
P1 is the initial pressure
V1 is the initial volume
P2 final pressure
V2 final volume
1.7 x 4.25 = 2.4 x V2
V2 = 3.01L
Answer:
You have to calculate
Explanation:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
Answer:
Lithium Fluoride
One lithium atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy.
Explanation:
They are called electron clouds because, 1) they are made up of electrons and 2) when seen in certain microscopes and in theory they look like clouds. Now I'm going to explain 2 in more detail. The cloud part is derived from the fact that what we think of electron orbits being defined circular orbits is false. The motion of electrons in an atom is undefined and unclear, but remains in a certain area- the electron cloud. When you hear the term, electron orbital, that is just the area in which you should expect to find an electron about 90% of the time.
Answer:
The magnetic field in the region a < r < b is 
Explanation:
If we have the a < r < b. The formula of current is:
Where:
A = area enclosed by the loop.
Itotal = total current in loop.
If we have the Ampere`s law:
