2. Conductor
3. Insulator
It's urgent please!​

Answer 1

Explanation:

1.An instrument for measuring temperature, especially one having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.

2. a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.

3.An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field

Answer 2

Answer:

1. device that measure the hotness and coldness of a body is called thermometer.

2. an object that allows heat/electricity to paas through them is called conductor

3. an object that doesn't allow heat/electricity to paas through them is called insulator.
