Why thermal conductivity of rusted iron decreases?
The thermal conductivity of rusted iron decreases because rust, which is mainly composed of iron oxides, is a poor conductor of heat compared to pure iron. The presence of the non-conductive iron oxide layer disrupts the flow of heat through the material, resulting in a lower thermal conductivity. Additionally, the formation of rust can create interfaces and boundaries within the material that further impede the transfer of heat.
Why is copper a better condutor of heat than iron?
Copper is a better conductor of heat than iron because it has a higher thermal conductivity. This is because copper's atomic structure allows heat to transfer more efficiently through its lattice. In contrast, iron has a lower thermal conductivity due to its crystal structure which hinders the flow of heat.
Can you provide specific heat sample problems for practice?
Here are a couple of specific heat sample problems for practice: Calculate the amount of heat required to raise the temperature of 50 grams of water from 20C to 40C. The specific heat capacity of water is 4.18 J/gC. A 25 gram piece of iron is heated from 25C to 100C. Calculate the amount of heat absorbed by the iron. The specific heat capacity of iron is 0.45 J/gC. These problems can help you practice applying the concept of specific heat in calculations.
Does aluminium have as high a specific heat capacity as iron?
No, aluminum has a lower specific heat capacity than iron. The specific heat capacity of aluminum is about 0.90 J/g°C, while iron has a specific heat capacity of about 0.45 J/g°C.
The indicator lamp in a dry iron comes on when the is plugged in but the iron does not heat up this is an indicator that the?
If the indicator lamp in a dry iron comes on when the iron is plugged into the power socket, but the iron does not heat up, it indicates that your iron has a problem with one of its electrical components.
How iron is heated due to electricity?
Iron (like all material) has resistance to current flow. When electrons do flow through iron you get the standard I squared R losses ... all of which is heat.
If a piece of iron with a temperature of 300 degrees celsius is dropped into a gallon of water with a temperature of 25 degrees Celsius heat will?
heat will flow from the iron to the water until both are the same temperature
What will best help determine the direction of heat flow in a system?
temperature
Where can you get a flow chart of iron production please help?
thanks for anyone help please its a homework really need it
Does a ironing board cover prevent heat flow or help it?
A ironing board cover helps to prevent heat transfer between the hot iron and the ironing board surface. The cover acts as a barrier to protect the board from heat damage and also provides a smooth, even surface for ironing clothes.
Does hot chocolate cool faster in a plasticstyrafoam or iron cup?
plasticstyrafoam iron. the metal conducts heat, the plastic insulates (holds the heat in) - about what you said, the metal does conduct heat, so that the hot sides help to heat up the drink.

Why is iron used in a saucepan?
Because its an excellent thermal conductor. Iron and aluminum help gather and store the heat used for cooking
What is something that slows the flow of heat?
Insulation materials such as fiberglass or foam slow down the flow of heat by reducing heat conduction. These materials have low thermal conductivity, which means they are not good conductors of heat and can help to trap heat within a space.
How will be the flow of heat if iron ball at 40degree celsius is dropped in mug containing water at40 degree celsius?
Heat will flow from the iron ball to the water in the mug until they reach thermal equilibrium, meaning both the iron ball and the water will eventually reach the same temperature. This process is governed by the laws of thermodynamics, specifically the second law which states that heat will always transfer from a hotter object to a cooler object until they reach the same temperature.

What kind of conversion take place in an electric iron?
I assume you are referring to energy conversions. Well, the whole PURPOSE of an electric iron is to produce heat, and being electric means that it uses electrical energy, so the conversion is, simply, from electrical energy to heat.
