Useful changes in materials often involve modifications to enhance their properties or functionalities. For example, alloying metals can improve strength, corrosion resistance, or thermal conductivity. Additionally, the development of composite materials combines different substances to achieve superior performance, like lightweight yet strong materials in aerospace applications. Innovations like smart materials that respond to environmental stimuli also represent significant advancements in material science.

What is halochromic?
A halochromic material is a material which changes color when pH changes occur.
What name do we give to temporary changes to a material?
Temporary changes to a material are known as physical changes. These changes do not alter the chemical composition of the material but only its physical properties such as shape, size, or state.
What name do we give temporary changes toa material?
Temporary changes to a material are referred to as "physical changes." These changes alter the state or appearance of a material without affecting its chemical composition, such as melting, freezing, or dissolving. Unlike chemical changes, physical changes are usually reversible.
Why is density is a useful physical property for identifying substances?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What are fematodine complex formations?
Femtosecond laser pulses can induce complex formations in materials by causing rapid and precise changes in their structure at the atomic level. These formations can include nanostructures, surface modifications, and phase changes, which can be useful in various applications such as material processing, optical devices, and biomedical applications.
What are Useful and Harmful Changes?
The changes talking place in our surroundings and which are useful to us are called Useful changes. The changes which are not useful but harmful are called Harmful changes
When is a material useful?
A material is useful when it possesses the desired properties for a specific application or task, such as being strong, lightweight, flexible, or insulating. Additionally, the material should be readily available, cost-effective, and environmentally friendly to be considered useful.
List down 10 useful 10 harmful changes in the environment?
changes both harmful and useful
What is halochromic?
A halochromic material is a material which changes color when pH changes occur.
What is a flexible property?
A flexible property is a characteristic of a material or substance that allows it to be bent, stretched, or deformed without breaking. This flexibility enables the material to adapt to changes in shape or position, making it useful for applications that require movement or deformation.
What name do we give to temporary changes to a material?
Temporary changes to a material are known as physical changes. These changes do not alter the chemical composition of the material but only its physical properties such as shape, size, or state.
What is the green material on card tables made of?
The material is simply:felt. I hope this was useful to you!
What is a useful material or other material that people take from the earth?
Natural Resources
What useful material can be mined from hematite?
Iron.
Which equipment is most useful when measuring two enviromental changes?
A thermometer and light meter are the most useful when measuring two environmental changes.
What name do we give temporary changes toa material?

When a material changes from a solid to a liquid the material is what?
solidifying.
