What else can I help you with?
Is thermal conductivity physical or chemical property?
Thermal conductivity is a Physical property
Iron is a good conductor of heat and electricity is this a chemical property?
It is NOT a chemical property. On both counts it is a PHYSICAL property.
What matter is heat conductivity chemical or physical change?
Heat conductivity is a physical property of matter, not a chemical change. It refers to the ability of a material to conduct heat through its structure without changing its chemical composition. Materials with high thermal conductivity can transfer heat more efficiently than those with low thermal conductivity.
Is thermal expansion and contraction a physical change?
Yes, thermal expansion and contraction are physical changes. They result from the change in temperature of a material, causing its molecules to either spread out (expansion) or come closer together (contraction), without altering the chemical composition of the substance.
What material has the highest coefficient of thermal expansion?
The material with the highest coefficient of thermal expansion is typically graphite.
Is thermal expansion a chemical change?
No, thermal expansion is a physical change, not a chemical change. It occurs when a material expands or contracts in response to changes in temperature, without any change in the chemical composition of the material.
What are not an example of thermal expansion?
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
Is thermal conductivity a chemical or a physical?
Thermal conductivity is a Physical property
Is expansion a phsical or chemical property?
physical
What are the chemical and physical properties of dental amalgam?
coefficient of thermal expansion chemical would be Galvanism,
Is thermal conductivity physical or chemical property?
Thermal conductivity is a Physical property
Is expanding a chemical or physical?
Expansion is a physical property.
How is hydrolysis similar to thermal expansion?
Both hydrolysis and thermal expansion involve a change in the structure of a substance. While hydrolysis is a chemical reaction that involves the breaking of bonds by adding water, thermal expansion is a physical process where materials expand or contract in response to changes in temperature.
Is thermal expansion chemical or mechanical weathering?
Thermal expansion is a type of mechanical weathering. It occurs when rocks expand and contract due to temperature changes, leading to stress and eventually fracturing of the rock.
What is mercury used for in a thermometer?
The thermal expansion of mercury is proportional and linear to temperature.
What NOT a physical property of matter ductility color thermal conductivity reactivity of water?
reactivity of water is a chemical property
Is a property of matter chemical or physical?
Matter has chemical properties (ex.: chemical reactivity) or physical properties (ex.: thermal conductivity).
