On a hot dry day, the amount of water vapour present in atmosphere is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. Hence, a desert cooler cools better on a hot dry day.
Frequency because all the other things may have to do with energy but frequency is the one that has to do with number of wavelength passed by a certain point or a certain time
Answer:
a)
b).
Explanation:
Given that
Boyle's law
P V = Constant ,at constant temperature
a)
Given that
We know that for PV=C
Now by putting the values
PV= 50 x 0.106
Where P is in KPa and V is in
b)
PV= C
Take ln both sides
So
lnP + lnV =lnC ( C is constant)
By differentiating
So
When P= 50 KPa
It indicates the slope of PV=C curve.
It unit is .
Or we can say that .
