WebAug 3, 2024 · An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties. WebSep 16, 2024 · All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample).

WebHowever, whenever a synthetic polymer is made, chains of varying length (varying n’s) are produced, and the product has a range of formula weights. Therefore, the “molecular weight” is really an average for the sample. To complicate the situation, there are several types of averages, depending on how the molecular weight is measured. reach on twitter

"WebThe flammable limits reported are usually corrected to a temperature of 32°F (0°C) and 1 atmosphere. Increases in temperature and pressure result in reduced lower flammable limits possibly below 1 percent and increased upper flammable limits. Upper limits for some fuels can approach 100 percent at high temperatures. " - How does flammability depend on chain length
