I got this info from kentuckycajun's post above. When it is arranged like this, you can see the affect tin has on the melting point of lead. It drops, then goes back up. The low point is at the eutectic - 63% tin, 37% lead. This information can be used to find the tin percentage of an unknown bar of solder. 621° = lead
Lead has a melting point of 327.462 degrees Celsius and a boiling point of 1749 degrees Celsius. It exists in the solid state at room temperature. Lead has a density of 11.3 grams per cubic ...
The melting point of a substance doesn't change with its mass. Therefore, for 1 kg of each substance, the melting point of tin would be 232°C and the melting point of lead would be 327°C. Explanation: The melting point of a substance is a unique characteristic and is not dependent on the amount or mass of the substance present
If lead's melting point is 327.5 °C, then: b) Lead is a solid at 310 °C – Below its melting point, lead remains solid. d) Lead is a liquid at 390 °C – Above its melting point, lead becomes liquid. Therefore, the correct statements are (b) and (d). Statement (a), claiming lead is a gas at 280 °C, is incorrect because lead would be a ...
The melting points of Tin and Lead do not change with mass. Hence, for 1 kg of these substances, the melting points will be the same as for 2 kg - 232 °C for Tin and 327 °C for Lead. Explanation: The student's question is about identifying the missing values in a table, where the mass and melting points of two substances, Tin and Lead, are given.
In general, the melting point of a substance depends on its physical properties and does not rely on its mass. This means that 1 kg of lead will have the same melting point as 2 kg of lead. However, the melting point of tin and lead are not provided for 1 kg. To know the exact values, we need more information on them.
The student investigated more physical properties than chemical properties of lead. A chemical property is any of a substance properties that is obvious after chemical reaction. Chemical reaction of lead in air: 2Pb + O₂ → 2PbO. Color, density, melting point and electrical conductivity are physical property.
Rank the following compounds in order of increasing melting point using the numbers 1-5. (Enter 1 for the lowest melting point and 5 for the highest melting point.) diamond LiCl C2H2 CaO CHCl3; Predict which substance in pair of compounds would have a higher boiling point: CH_3CH_2CH_2CH_2OH vs CH_3CH_2CH_2CH_2NH_2.
The melting point of a substance, which is usually a temperature value, is that actual temperature the change of state occurs. According to this question, the melting point of Lead (Pb), which is naturally a solid metal, is 327.5°C. This means that LEAD (Pb) will only change to its liquid state at exactly 327.5°C and above.
- For lead: - Given the melting point of 2 kg of lead is . - Similar to tin, the melting point for 1 kg of lead is also . Therefore, . In conclusion, both and are equal to the melting points given for 2 kg of each substance, as the melting points are independent of the mass.
