it melts
Iron has the lowest specific heat, so it will heat up faster.
Yes, iron typically warms up faster when heat is applied due to its high thermal conductivity, allowing it to quickly transfer heat throughout its structure. This is why iron is commonly used in cooking utensils and heating devices.
Silver. because silver is good conductor of heat.
Heat cannot be transferred in this way with an iron rod because iron is a good conductor of heat. When the iron rod is held at one end and heat is applied to the other end, the heat energy will quickly travel through the iron rod, leading to a uniform temperature distribution along the rod.
compound of iron
The iron and sulfur react to form the compound iron sulfide.
Heat must have to be applied to the ice cube.
When heat is applied to powdered sulfur, it will melt and eventually vaporize. This process is called sublimation, where a solid substance bypasses the liquid phase and turns directly into a gas.
heat is transferred only from high energetic concentration to low energetic concentration. therefore heat cant be transferred in any usual way.
differentiate luminous flame from non-luminous flame
When wet iron filings react with air and salt, the salt acts as a catalyst to speed up the oxidation process of iron. As the iron oxidizes (rusts) in the presence of oxygen from the air, energy is released in the form of heat. This reaction is exothermic, meaning it releases heat energy as a byproduct.
When heat is applied to an iron nail, the thermal energy causes the iron atoms to vibrate more rapidly, increasing their kinetic energy. As a result, the iron nail will expand due to the increased movement of the atoms. This expansion is a result of the increase in temperature causing the atoms to move further apart, leading to a temporary increase in the length of the nail.
