4 grams of a saturated liquid are converted to a saturated vapor by being heated in a weighted piston–cylinder device arranged t
o maintain the pressure at 200 kPa. During the phase conversion, the volume of the system increases by 1000 cm3, 5 kJ of heat are required, and the temperature of the substance stays constant at 80°C. Estimate the sfg of the substance when its temperature is 80°C.

Answer:
The load reflection coefficient,
Reflection coefficient at input,
SWR = 4.26
Given:
Characteristic impedance of the co-axial cable,
Length of the cable, L = 2.0 cm = 0.02 m
Dielectric constant, K = 2.56
frequency, f = 3.0 GHz =
Explanation:
In order to calculate the reflection coefficient at load, we first calculate these:
The line input impedance is given by:
(1)
Now, we calculate the value of :
(since, )
Now, Substituting the value in eqn (1):
Now, the load reflection coefficient is given by:
Thus
Similarly,
Reflection coefficient at input:
Now, the SWR is given by:
SWR, Standing Wave Ratio =
SWR =
Answer:
the atomic radius of a lithium atom is 0.152 nm
Explanation:
Given data in question
structure = BCC
lattice constant (a) = 0.35092 nm
to find out
atomic radius of a lithium atom
solution
we know structure is BCC
for BCC radius formula is /4 × a
here we have known a value so we put a in radius formula
radius = /4 × a
radius = /4 × 0.35092
radius = 0.152 nm
so the atomic radius of a lithium atom is 0.152 nm
