Petrified wood is an example of altered remains. The pores of the wood are filled in with silica.
Yes, ripping your notebook is a physical change because the substance (paper) remains the same, only its shape has been altered. The paper molecules are not chemically altered during the ripping process.
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
When you create a mixture and a change occurs, it is called a physical change. This means the substance's state or appearance has altered, but its chemical composition remains the same.
No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.
Yes, ripping your notebook is a physical change because the substance (paper) remains the same, only its shape has been altered. The paper molecules are not chemically altered during the ripping process.
If the deciduous forest remains unchanged, it will maintain its status as a deciduous forest. Deciduous forests are characterized by trees that shed their leaves each year, and this ecosystem type remains the same as long as the conditions that support it are not significantly altered.
It is impossible to shift the past. Time-travel remains a theoretical concept, and while memories can be altered or distorted, events that have already occurred cannot be changed.
The frequency of light remains unchanged when it travels from one transparent medium to another. Only the speed and wavelength of light are altered as it transitions between different mediums.
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
Sanding a piece of paper is a physical change because the paper's appearance and texture are altered, but its chemical composition remains the same.
When you create a mixture and a change occurs, it is called a physical change. This means the substance's state or appearance has altered, but its chemical composition remains the same.
Altered State - Altered State album - was created on 1991-08-27.
Slicing a mango is a physical change because only the physical appearance and state of the mango are altered, while its chemical composition remains the same.
Yes, it is a physical change.
The book had clearly been altered. She altered my dress so it fit me. If your ticket is altered in any way, you cannot get into the concert.
