Unformatted text preview: • • (A) (B) sucrose + water water c t Physics 7B-A/B Quiz # 3 DL sec: Name: 2/6/08 last, frst Codes: grading use only • • (A) (B) sucrose + water water c t 1.)

Two
containers
are
connected
by
a
tube
 of
interior
cross
section
area
1.2
ª
10-4
 m 2 

 and
length
8.0
cm
shown.

The
container
on
 the
left
contains
water,
and
the
container
on
 the
right
contains
water
with
a
high
 concentration
of
sucrose.

The
diffusion
 constant
for
sucrose
in
water
is
 5.0
ª
10-10 m 2 /s

.

The
initial
diffusion
current
in
the
tube
for
the
sucrose
is
 3.0
ª
10 15 
s-1 . a)

(10%)
Which
direction
will
the
sucrose
in
the
tube
flow? The
sucrose
will
flow
toward
lower
concentration;
hence,
to
the
left. b)

(10%)
During
a
time
when
the
flow
is
approximately
steady,
is
the
diffusion
current
at
point
 (A)
greater
than,
less
than,
or
the
same
as
the
diffusion
current
at
point
(B)? The
currents
must
be
the
same
to
conserve
particles....
