Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
Are specific gravity of the material will give effect to strength of concrete?
The specific gravity of materials tell us how many times is the material heavier than water. The higher the specific gravity of a material the higher the density of concrete made with and the higher will be the force require to crush it and the higher will be the corresponding strenght of the concrete
Why is aerated concrete a better insulator than normal concrete?
Air has a higher specific heat capacity (at 1.0035 J/(g*K)) than concrete (.880 J/(g*K)).Specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by unit degree (Wikipedia). Because air requires more joules of energy per gram to raise it one degree Kelvin than concrete does, it is therefore a better insulator.
What are dielectrics?
Dielectrics is a fancy term for insulators, based on the material used and its efficiancy at a measured range of frequencies. For example, in a coaxial cable, the better it isolates the main frequency from feeding through to the shield, the higher the dielectric value.
Are more Hz on a tv better?
The higher the Hz on your TV, the more fluid the pictures will seem to your eye. In general, a higher refresh (Hz) rate is better, but you might not be able to tell much, or any difference depending on what you're watching.
Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
Is a material with a lower R-value is a better insulator?
Higher
What is a better insulator plastic foam or wrap?
Plastic foam is generally a better insulator than wrap because it has a higher R-value, which measures the material's resistance to heat flow. Foam insulation can provide better thermal performance and help reduce energy costs more effectively than wrap.
Why is polystyrene a better insulator than wool?
Polystyrene has a lower thermal conductivity than wool, meaning it is a better insulator. Polystyrene is a synthetic material with a closed-cell structure, which reduces heat transfer through conduction. Wool, being a natural fiber, has a higher thermal conductivity and can absorb moisture, affecting its insulating properties.
The more voltage that is required to break down an insulator the greater its?
dielectric strength. Dielectric strength refers to the maximum electric field that a material can withstand without breaking down and allowing current to flow through it. Materials with higher dielectric strength are better insulators and can withstand higher voltages.
Which resistor is the better insulator 24 or 6?
The resistance value of a resistor indicates how well it can insulate against the flow of electric current. A 24-ohm resistor has a higher resistance compared to a 6-ohm resistor, meaning it is better at restricting current flow and thus acts as a better insulator. Therefore, the 24-ohm resistor is the better insulator.
Is oven glove a conductor or an insulator?
an insulator.
Is rubber or wood a better insulator?
Rubber is a better insulator than wood. Rubber contains a higher concentration of insulating properties, such as resistance to electricity and heat transfer, making it more effective in blocking the flow of energy compared to wood.
What does a higher thermal conductivity indicate about a material's ability to transfer heat?
A higher thermal conductivity indicates that a material is better at transferring heat.
Is air a better insulator than fiber glass?
No, fiberglass is a better insulator than air. Fiberglass has a higher R-value, which measures its resistance to heat flow, compared to air. Fiberglass is commonly used as insulation in buildings to improve energy efficiency.
Is glass or metal a better conductor?
Glass has a higher conductivity than thin plastic but,it is still lower than metal so metal may be a better conductor
When the thermal conductivty is higher what is it mean?
When thermal conductivity is higher, it means that the material is better at conducting heat. This means that heat transfers more easily through the material, making it a better conductor of heat compared to a material with lower thermal conductivity.
