it is chemical change
When a seismic wave crosses a boundary, it will change directions in the process of refraction. This occurs because the wave travels at different speeds in different materials, leading to a bending of the wave path as it enters a new medium. The extent of this change in direction depends on the properties of the materials involved, such as density and elastic properties.
When solid materials are mixed with other solid materials, their properties can change depending on factors such as the size, shape, and composition of the particles involved. The resulting mixture may exhibit altered mechanical properties, such as strength, hardness, and elasticity, due to interactions between the different components. Additionally, the mixture's density, porosity, and thermal or electrical conductivity can also be affected. Overall, the behavior of the mixed solids is influenced by the nature of their interactions and the ratio of each material present.
Burning of wood and paper is a chemical change because it involves a chemical reaction where the substances are transformed into new substances (ashes, carbon dioxide, etc.) with different properties than the original materials.
Density is a physical property that depends on the mass of a substance and its volume. It is independent of temperature but can change with different materials. Different materials have different densities due to variations in their mass and volume.
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
No, light does not cause the same change to all materials. Different materials react differently to light, depending on their properties and composition.
Yes, materials do change when physical properties are measured.
by raw materials that changes materials
Materials lose their original properties when their spatial conditions change, provided their atomic configuration change.
Absorption of light by materials can cause them to heat up, change color, or emit light. Different materials absorb light differently based on their properties, such as transparency or reflectivity. This absorption process can impact the behavior of materials by influencing their physical and chemical properties.
Light can have different effects on materials depending on their properties. Some materials may absorb light and heat up, while others may reflect or transmit light. The change caused by light can vary among different materials, as each material reacts differently to light exposure.
No
Materials such as metal, glass, and plastic can undergo changes in physical or chemical properties when subjected to heat. These changes may include melting, reshaping, or even chemical reactions that result in a transformation into a different material.
A mixture is the combination of two or more materials where the properties of the individual materials remain unchanged. Each component retains its original characteristics and can be separated back out.
Functionally graded materials are materials with properties that change gradually over their structure, rather than abruptly. This gradient in properties allows for better adaptation to different requirements or conditions in the material's application. FGMs are used in various engineering fields to improve performance and durability.
These are called transverse waves. As they travel through different materials, their speed can change based on the properties of the material, such as its density or elasticity. Examples include light waves and seismic waves.
No, heat affects different materials in different ways. Some materials expand when heated, while others contract. Some materials may change their chemical or physical properties when heated, leading to changes in color, shape, or state. Conductive materials will transfer heat more easily than insulating materials.
