Detonation involves a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations are observed in both conventional solid and liquid explosives, as well as in reactive gases.
Deflagrations are thermal radiations. They move outward along with available fuel, away from the ignition point.
18. Explain the terms: Boyles Law, the Combined Gas Law and the Ideal Gas Law. Include equations. Using the Ideal Gas Law solve the following problems:
Boyles Law: describes the inversely proportional relationship of pressure and volume of gas, assuming constant temperature within a closed system
pV=K
where p: pressure
v= volume
k- constant value
Combined Gas Law: a combination of 3 gas laws, namely Charle's law, Boyle's law and Gay-Lussac's law.
PV/T =K
where p: pressure
v: volume
T: temperature measured in kelvin
k: constant
Ideal Gas Law: it is an equational representation of the ideal gas.
PV=NkT
where:
p: absolute pressure
V: volume
N: number of particles in a gas
k: Boltzmann's constant relating temperature
T: absolute temperature.
a. If there are 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature?
567 420 pascals (0.012 cubic meters )= 4(1.38•10−23 ) T
6809.04=0.0000000000000000000000552(T) T= 81069 x 10^-26
b. If there is an unknown quantity of gas at a pressure of 1.2 atm, a volume of 31 liters, and a temperature of 87 0C, how many moles of gas do I have?
PV=NkT
1.2 ATM(31 Litres)= 87( 1.38•10−23) (moles)
121 590 pascals(0.031 cubic meters) = 360.15( 1.38•10−23) N
3769.29 = 0.
