Porosity decreases the heat conductivity of a material because the void spaces act as barriers to the flow of heat. This is because air or other insulating gases within the pores have lower thermal conductivity compared to the solid material. As a result, materials with high porosity generally exhibit lower heat conductivity.
What else can I help you with?
The ability of a material to transfer heat or electric current is called A insulation C conductivity B porosity D convection?
The ability of a material to transfer heat or electric current is called conductivity. It measures how easily heat or electricity can move through a material. Insulation, on the other hand, is the resistance to the flow of heat or electricity.
Is heat conductivity the same thing as thermal conductivity?
Yes, heat conductivity and thermal conductivity are often used interchangeably to describe the ability of a material to conduct heat. Both terms refer to how well a material allows heat to flow through it.
What is the rate at which a substance transfers heat?
conductivity
Does the value of thermal conductivity depend on the dimension of the specimen?
Thermal conductivity is an intensive property. It is inherent in the material but not dependent on the amount of material. This should not be confused with the rate of heat conduction which can depend on the dimensions of a material. There is one case where the thermal conductivity might depend on the dimension of the material - when the conductivity is not uniform with direction, i.e. where conductivity laterally is different from conductivity longitudinally. When the orientation of the material changes the conductivity, the dimensions can have an effect on the apparent bulk thermal conductivity.
Thermal conductivity is the ability of an element to transfer what?
Thermal conductivity is the ability of an element to transfer heat. It quantifies how fast heat can be transferred through a material under a temperature gradient. Materials with high thermal conductivity can transfer heat quickly, while materials with low thermal conductivity transfer heat more slowly.

Is heat conductivity a physical change or chemical change?
The heat conductivity of a substance does not involve changes to its chemistry. Heat conductivity is a physical change and characteristic to a substance.
What are two factors about the particles in a rock have the greatest effect on the porosity of the rock?
Porosity refers to the measure of how much of a rock is open space. The two factors concerning particles in a rock that have the greatest effect on the rock's porosity are shape and distribution.
Does porosity effect building materials?
Yes it does.
Which has maximum conductivity of heat?
Copper has the highest conductivity

What type of Conductivity refers to carrying heat?
Thermal conductivity refers to a material's ability to conduct heat. It measures how effectively heat can move through a substance. Materials with high thermal conductivity are good conductors of heat, while those with low thermal conductivity are poor conductors.
What is the ability to transmit heat or energy?
Thermal conductivity is the ability of a material to conduct heat or energy through it. It is a measure of how quickly heat can pass through a material. Materials with high thermal conductivity are good conductors of heat, while those with low thermal conductivity are good insulators.
What does heat conductivity do on denim fabrics?
Heat conductivity in denim fabrics determines how quickly heat transfers through the material. Denim with higher heat conductivity will feel cooler to the touch as it allows heat to escape more easily, making it breathable and comfortable in warm conditions. Conversely, denim with lower heat conductivity may feel warmer as it retains heat better.
