What else can I help you with?
What would happened if you used glass beaker for a calorimeter instead of sytrofoam cup?
Using a glass beaker instead of a styrofoam cup for a calorimeter could lead to greater heat loss to the surroundings due to the higher thermal conductivity of glass. This can result in inaccurate measurements of heat transfer during a calorimetry experiment. Styrofoam cups are better insulators and help to minimize heat loss.
Is molten lead a conductor or insulator?
Molten lead is a good conductor of electricity because the atoms are free to move and carry electric charge.
Which metal is the poorest conductor of heat?
Most of the metals are good conductors of heat and electricity. Exception to this rule is silver and copper. Spoons made out of silver and copper pans used in cooking does not conduct heat easily.
Why does hot oil break glass and not hot water?
The boiling point of oil is higher than water and absorbs more heat .When hot oil is poured in a glass container the heat is conducted through the cold glass which expands and breaks while in hot water the heat energy absorbed is less and the glass heat is dissipated slowly to avoid sudden expansion.
What is the physical properties difference between lead and copper?
Lead is a heavy, soft, and malleable metal with a dull luster, while copper is a relatively lightweight, ductile, and malleable metal with a bright metallic luster. Lead has a lower melting point and is more resistant to corrosion than copper. Copper is a better conductor of electricity and heat compared to lead.
Does glass lead heat?
Yes, glass will conduct heat, only not as well as metals.
What does glass do with heat?
Glass is a poor conductor of heat, meaning it does not easily transfer heat energy. It can reflect some heat, absorb some, and transmit some, depending on the type of glass and its thickness. When heated, glass expands, which can sometimes lead to cracking if the temperature change is too sudden or extreme.
Is lead a cconductor or insulator of heat?
Like all metals, a conductor, but not as good a conductor as, for example, silver or copper.
Are lead good conductor of heat?
No, lead is not a good conductor of heat. It has a low thermal conductivity compared to other metals such as copper or aluminum.
Is lead a good conductor of heat?
maybe..
What is the poorest electrical conductor is it pencil lead glass steel or aluminum?
Pencil lead is the poorest electrical conductor among the materials listed. While steel and glass are poor conductors, aluminum is a relatively good conductor of electricity.
Why is lead a poor conductor of electricity but a good conductor of heat?
Lead is 12th on the list of conductive metals, with Silver, Copper and Gold being the best conductors. The better conductors have to do with available electrons in the conduction band of the metal.
Is a iron nail a good heat conductor?
Yes. But, compared to what? Better than lead but not as good as silver.
Is lead conductor?
Lead has high resistivity of current. So , lead is not conduct current. But lead has low resistivity of heat and it conduct heat..
A good heat conductor is a?
Copper, aluminum, gold, iron, silver, lead, tin, platinum, nickel, tungsten A and example of a good conductor of heat is a metal.
Why lead is poorest conductor of heat?
Lead is a poor conductor of heat because it has a low thermal conductivity due to its atomic structure. Lead atoms are arranged in a way that does not allow for efficient transfer of heat energy through the material. Additionally, lead has a relatively high density and atomic mass, which further hinder the movement of heat within the material.
Examples of bad conductor of heat?
Most things are not conductors of heat, or electricity. This means that the substances contain a large number of free electrons. Some of these are water, plastic, rubber, glass, lead, and wood.
