What else can I help you with?
Which warms up faster when heat is applied iron water sand or wood?
Iron has the lowest specific heat, so it will heat up faster.
Does iron normally warm up faster when heat is applied?
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.
Which warms up faster when heat is applied iron or silver?
Silver. because silver is good conductor of heat.
Why can heat not be transferred in this way with an iron rod?
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.
Why does heat applied to a substance change its temperature or make it change its phase?
compound of iron
What happen in the iron fillings and sulfur powder if they heat together?
The iron and sulfur react to form the compound iron sulfide.
What would have to happen to make an ice cube melt?
Heat must have to be applied to the ice cube.
What will happen to the powdered sulfur when heat was applied?
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.
Why heat can not be transferred in this way in an iron rod?
heat is transferred only from high energetic concentration to low energetic concentration. therefore heat cant be transferred in any usual way.
What happen if heat is applied mat the bottom of the test tube?
differentiate luminous flame from non-luminous flame
How does the reaction between wet iron filings air and salt happen to produce heat?
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.
What happens when you add heat to an iron nail?
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.
