Answer:
Given that
V2/V1= 0.25
And we know that in adiabatic process
TV^န-1= constant
So
T1/T2=( V1 /V2)^ န-1
So = ( 1/0.25)^ 0.66= 2.5
Also PV^န= constant
So P1/P2= (V2/V1)^န
= (1/0.25)^1.66 = 9.98
A. RMS speed is
Vrms= √ 3RT/M
But this is also
Vrms 2/Vrms1= (√T2/T1)
Vrms2=√2.5= 1.6vrms1
B.
Lambda=V/4π√2πr²N
So
Lambda 2/lambda 1= V2/V1 = 0.25
So the mean free path can be inferred to be 0.25 times the first mean free path
C. Using
Eth= 3/2KT
So Eth2/Eth1= T2/T1
So
Eth2= 2.5Eth1
D.
Using CV= 3/2R
Cvf= Cvi
So molar specific heat constant does not change
The answer should be d because they are constantly rotating
Answer:
A naturally radioactive element of the actinide metals series. Plutonium is used as a nuclear fuel, to produce radioisotopes for research, Plutonium dioxide is formed when plutonium or its compounds (except the phosphates) are ignited in air, and Plutonium oxide fired at temperatures 600 C is difficult to rapidly.
Explanation:
It should be a metamorphic rock as those rocks are formed due fue to heat and pressure
Answer:
The answer is c) while the statement is false, the given reasons for it being false are incorrect.
Explanation:
The speed of a chemical reaction must be proportional to the number of molecules per unit of time with enough energy to achieve the transition state. This transition state has an energy superior to that of the reagents and that of the products, establishing among them an energy barrier that has to be overcome in order for the reaction to take place.
