Answer:
its caused by the convection of air masses with differences in densities mainly due to their differences in temperatures.
-Hops
The rate of change in velocity<span> is called acceleration.</span>
Answer:
C) The student and desk have to be in contact to apply the force.
Explanation:
I am pretty sure :)
Solution is here,
for initial case,
temperature(T1)=70°C=70+ 273=343K
vloume( V1) =45 L
for final case,
temperature( T2)=?
volume(V2)= 91.3 L
at constant pressure,
V1/V2 = T1/T2
or, 45/91.3 = 343/ T2
or, T2= (343×91.3)/45
or, T2=695.9 K = (695.9-273)°C=422.9°C
