Activity 2 (Thermal conductivity of metals and non-metals)
Note: This activity needs to be performed carefully in the presence and with the assistance of a
Iron nail
Copper
wire
Wax
1
.
Approximate duration: 30 minutes
Aim: To compare the thermal conductivities of metals and non-metals
Materials required: Copper or aluminium wire, carbon or graphite
rod, spirit lamp or Bunsen burner
, wax, laboratory stand and needles
Procedure:
Take the copper or aluminium wire and fix the wire to a stand. Attach
a pin to one of the free ends of the wire using wax, as shown in the
figure.
2. Start heating the wire from its other free end using a spirit lamp or
a Bunsen burner.
3. Observe whether the wax melts or not and the pin falls or not.
4. Repeat the same procedure with a carbon or graphite rod and
record your observations,

Answer 2

Hello friends here is the answer

Copper transfers maximum heat and followed by brass. Steel is the least conductor of heat. The conductivity of heat is the major property of an object and copper has the highest and steel has the lowest conductivity of heat.
