The main objective of this experiment is to differentiate between a physical change and a chemical change. A physical change includes a change in the material without affecting its composition‚ such as the physical state change. However‚ a chemical change includes the change in the composition of the substance. The change in color‚ formation of a gas or a solid product‚ and the production of energy are the evidences of a chemical reaction‚ thus‚ of a chemical change. Materials Crucible

term ‘physical change’ A physical change is where the appearance or traits of the substance/item change these changes can be‚ change of size‚ shape‚ color‚ volume and state. The molecules in the substance can be rearranged but their composition must stay the same. No new substance can be formed. They can be reversed most of the time. 2. Describe one example of a physical change in everyday life and explain why it is a physical change. Melting an ice cube is a common physical change. Melting an ice

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

History are filled with interesting events and persons. Based on the material I learned during this semester in class‚ the event that strike me the most was the Spanish conquest of the Aztec Empire. European rulers wanted explorers to find riches to bring back to Europe. Hernán Cortés led an expedition to Mexico in 1519. His ships carried 400 conquistadors with horses and weapons.

is a chemical change‚ but it is actually a physical change. This is because the pieces that caused the reaction are still there‚ but they have just been rearranged. This also means that changing some of the factors in this experiment might cause another physical reaction to occur on a smaller or even larger scale.(Science Buddies) What you see when mentos are put into diet coke is that the coke spews out of it’s container once contacted with the mentos.
