Assertion : At same temperature among plastic body of pen and metal portion on cap, metal portion is cold.
Reason : Thermal conductivity of metal is more than plastic.

A

Both are true and the reason is the correct explanation of the assertion.

B

Both are true but the reason is not correct explanation of the assertion.

C

Assertion is true, but the reason is false.

D

Both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Assertion is correct as per experience.
Thermal conductivity of metal is more than plastic When we touch metal, our body heat transfers to it immediately but it is not done in plastic hence, metal is felt to be cool.
Thus, reason is correct explanation.

Assertion: Neutral temperature of a thermocuple does not depend upon temperature of cold junction. Reason: Its value is constant for the given metals of the couple

A cylindrical block of length 0.4 m and area of cross-section 0.04 m^2 is placed coaxially on a thin metal disc of mass 0.4 kg and of the same cross - section. The upper face of the cylinder is maintained at a constant temperature of 400 K and the initial temperature of the disc is 300K . if the thermal conductivity of the material of the cylinder is 10 "watt"// m.K and the specific heat of the material of the disc is 600J//kg.K , how long will it take for the temperature of the disc to increase to 350 K ? Assume for purpose of calculation the thermal conductivity of the disc to be very high and the system to be thermally insulated except for the upper face of the cylinder.

A closed cubical box is made of perfectly insulating material and the only way for heat to enter or leave the box is through two solid cylindrical metal plugs, each of cross sectional area 12cm^(2) and length 8cm fixed in the opposite walls of the box. The outer surface of one plug is kept at a temperature of 100^(@)C . while the outer surface of the plug is maintained at a temperature of 4(@)C . The thermal conductivity of the material of the plug is 2.0Wm^(-1).^(@)C^(-1) . A source of energy generating 13W is enclosed inside the box. Find the equilibrium temperature of the inner surface of the box assuming that it is the same at all points on the inner surface.

Assertion: Current is passed through a metallic wire, heating it red. When cold water is poured on half of its portion, then rest of the half portion become more hot. Reason: Resistance decreases due to decrease in tem perature and so current through wire increases.

A metal rod A of length l_(0) expands by Deltal when its temperature is raised by 100^(@)C . Another rod B of different metal of length 2l_(0) expands by Deltal//2 for same rise in temperature. A third rod C of length 3l_(0) is made up of pieces of rods A and B placed end to end expands by 2Deltal on heating through 100K . The length of each portion of the composite rod is :-

An amount of heat passing through a metallic rod in time t is given by Q=(KA(T_(1)-T_(2))t)/(I) where k= thermal conductivity A= Cross sectional area, T_(1) and T_(2) are temeprature of hot and cold ends respectively and L= length. So the dimesional formula for k=.....

A ring consisting of two parts ADB and ACB of same conductivity k carries an amount of heat H The ADB part is now replaced with another metal keeping the temperature T_91) and T_(2) constant The heat carried increases to 2H What should be the conductivity of the new ADB Given (ACB)/(ADB)=3 .

Explain why : (a) Two bodies at different temperatures T_1 and T_2 if brought in thermal contact do not necessarily settle to the mean temperature (T_1 + T_2 )//2 . (b) The coolant in a chemical or a nuclear plant (i.e., the liquid used to prevent the different parts of a plant from getting too hot) should have high specific heat. (c) Air pressure in a car tyre increases during driving. (d)The climate of a harbour town is more temperate than that of a town in a desert at the same latitude.

Asseration: A metal piece and a non-metal (stone) piece are dropped from the same height near earth's surface. Both will reach the earth's surface simultaneousely. Reason: There is no effect of earth's magnetic field on freely falling body.
