Two identical conducting rods are first ...

Two identical conducting rods are first connected independently to two vessels, one containing water at `100^@C` and the other containing ice at `0^@C`. In the second case, the rods are joined end to end and connected to the same vessels. Let `q_1 and q_2` gram per second be the rate of melting of ice in the two cases respectively. The ratio `q_1/q_2` is
(a) `1/2` (b)`2/1` (c)`4/1` (d)`1/4`

Two identical conducting rods are first connected independently to two vessels, one containing water at 100^(@)C and the other containing ice at 0^(@)C . In the second case, the rods are joined end to end connected to the same vessels. Let m_(1) and m_(2) g/s be the rate of melting of ice in the two cases respectively, the ratio (m_(1))/(m_(2)) is

Two identical rods are connected between two containers on of tehm is at 100^@C and another is at 0^@C. If rods are connected in parralel them the rate of melting of ice is q_1 gm//sec. If they are connected in series then the rate is q_2. The ratio q_2//q_1 is

Six identical conducting rods are connected as shown in figure. In steady state temperature of point phi_(1) is fixed at 100^(@)C and temperature of phi_(6) at -80^(@)C Q. What is the temperature of phi_(2) ?

One end of a cylindrical rod is kept in steam chamber and the other end in melting Ice. Now 0.5gm of ice melts in 1sec if the rod is replaced by another rod of same length half the diameter then rate of melting of ice will be (in gm/sec) .

Two identical rods are connected between two containers. One of them is at 100^(@)C containing water and another is at 0^(@)C containing ice. If rods are connected in parallel then the rate of melting of ice is q_(1)g//s . If they are connected in series then teh rate is q_(2)g//s . The ratio q_(2)//q_(1) is

Two identical rods are connected in parallel. One end of the rods is maintained at 100^(@)C and other end is kept in 0^(@)C ice . The rate at which the ice melts is Q_(1) gm/sec . Now the rods are connected in series . The ends are again maintained at 100^(@) C and kept in 0^(@)C ice . Now the rate at which ice melts is Q_(2) gm/sec . Then Q_(2) //Q_(1) is

Two conducting rods when connected between two points at constant but different temperatures separately, the rate of heat flow through them is q_1 and q_2 .

Two conductors, one having resistance R and another 3R are connected in turn across a d.c. source. If the rate of heat produced in the two conductors is Q_(1) and Q_(2) respectively, then find their ratio.

A cylindrical rod with one end in a steam chamber and the other end is in ice It is found that 1gm of ice melts per second If the rod is replaced by another one of same material double the length and double area of cross section, The mass of ice that melts per second is .

One end of a brass rod of length 2.0 m and cross section 1cm^2 is kept in stream at 100^@C and the other end in ice at 0^@C . The lateral suface of the rod is covered by heat insulator. Determine the amount of ice melting per minute. Thermal conductivity of brass is 110 W//m-K and specific latent heat of fusion of ice is 80 cal//g .
