Here's my attempt for the first part:
For the first body, the work obtained is
##W_1 = C_P (T_1 - T_f)##
while for the second body, it is
##W_2 = C_P(T_2 - T_f).##
So the net work obtained is the sum of these two:
##W = W_1 + W_2 = C_P (T_1 + T_2 - 2 T_f)##
and that proves the first part...
I have tried to do this using arrays and do loops:
program matrixmul
implicit none
real A(2, 2), B (2, 2), C (2, 2)
integer i, j, k
write (*, *) 'Input: First matrix'
do i = 1, 2
do j = 1, 2
read (*, *) A (i, j)
enddo
enddo
write (*, *) 'Input: Second...
Yes, I also thought of the density and checked again, but the question didn't supply any such information.
Also, thanks for the article, I'll take a look :) !
Here's how I approached it. We know the total mass of the cloud, it is given. Let's call it 'M'. We can also find out the mass of a single hydrogen atom from its atomic weight. Let's call this 'm'. Then
N = M / m
is the total number of hydrogen atoms in the cloud. The temperature (T) is given...
The question says that the process is melting, so temperature must increase.
Hence, Delta T > 0.
Also, it is given that the slope for its fusion curve is -ve, which means that as we increase temperature, the pressure will decrease.
So, Delta P < 0.
The question asks to prove that the substance...
Problem Statement: 1 kg of water at 273 K is brought into contact with a heat reservoir at 373 K. When the water has reached 373 K, what is the entropy change of the water, of the heat reservoir, and of the universe?
Relevant Equations: dS=Cp*(dT/T)-nR*(dP/P)
dS=Cv*(dT/T)+nR*(dV/V)
I am...
