Question

What best describes the degree to which a material can transmit heat

- melting point
- boiling point
- thermal conductivity
- electrical conductivity

Answer 1

BOILING POINT BECAUSE BOILING POINT IS THE POINT AT WHICH A MATERIAL OR SUBSTANCE IS MADE PURE AND FOR A SUBSTANCE TO BE MADE PURE IT NEED TO ABSORB AND GIVE OUT HEAT COS BOILING REACTION IS EXOTHERMIC

Answer 2

The correct answer is C. Thermal conductivity

Explanation:

Conduction occurs as heat, electricity, etc. are transmitted from one body to another. In the case of thermal conductivity, this refers to the property of one material or body to transmit or conduct heat. This property is measured in Watts (energy) per meter(distance)-Kelvin (temperature). For example, the thermal conductivity of copper is around 385 while the one of ice is 1.6, which indicates copper has a higher capability to conduct heat. Thus, the degree to which a material can transmit heat is thermal conductivity.
