Iron does not rust even if zinc coating ...

Iron does not rust even if zinc coating on its surface is broken but the same is not true when coating is of tin.

Text Solution

AI Generated Solution

To understand why iron does not rust when coated with zinc but does rust when coated with tin, we need to analyze the reactivity of these metals and their behavior in the presence of moisture and oxygen. ### Step-by-Step Solution: 1. **Understanding Rusting**: Rusting of iron is an electrochemical process that occurs when iron reacts with oxygen and moisture to form iron oxide (rust). This process can be prevented by coating the iron with a more reactive metal. 2. **Reactivity Series**: ...

The peak emission from a black body at a certain temprature occurs at a wavelength of 9000 Å . On increase its temperature , the total radiation emmited is increased its 81 times. At the intial temperature when the peak radiation from the black body is incident on a metal surface , it does not cause any photoemission from the surface . After the increase of temperature, the peak from the black body caused photoemission. To bring these photoelectrons to rest , a potential equivalent to the excitation energy between n = 2 and n = 3 bohr levels of hydrogen atoms is required. Find the work function of the metal.
