Answer:
option C
multiplication factor n = 1 when volume change to half and pressure become double
Explanation:
we know by Ideal Gas law:
P1V1 = nRT1
P2V2 = nRT2
according to the question
pressure is doubled and volume is reduced to half
so we have
new pressure = 2*P1
new volume = V1/2
hence,
(2P1) * (V1/2) = nRT2
P1V1 = nRT2
we have now
nRT1 = nRT2
we get
T1 = T2
thus no change in temperature
we know that internal energy is given as
internal energy = nCvT,
since temperature is directly proportional to internal energy and since temperature remains constant therefore internal energy remains constant
So there is no change in internal energy
thus, multiplication factor n = 1 when volume change to half and pressure change to double
Answer:
Time=7.84hrs
Explanation:
This is an inverse proportionality questions
Mathematically time t varies as 1/distance d
Hence T= dk/r
But speed r = distance/t
d= r*t= 9*20=180km/hr
We're k= constant of proportionality
At t=9hrs d=180km/hr
Hence k=r*t/d=20*9/1620=0.111
Finding t at at 1620km for 23km/hr
t=1620*0.111/23=7.84hrs
a steep-sided valley formed by the downward displacement of a block of the earth's surface between nearly parallel faults or fault systems.
Answer:
True
Explanation:
Electronegativity difference of less than 0.4 characterized covalent bonds. For two atoms with an electronegativity difference of between 0.4 and 2.0, a polar covalent bond is formed-one that is neither ionic nor totally covalent.
