How alloy bronze is obtained?
Bronze is obtained by mixing copper with other metals, typically tin. The specific proportions of copper and tin can vary, but typically bronze contains around 90% copper and 10% tin. The metals are melted together and then cooled to form the alloy bronze.
Is bending copper a physical of chemical change?
Yes this is a physical change because they are melting it and then it's being changed by the heat of the torch but heat is a physical change.
When you mix copper and tin you make bronze. No chemical reaction occurs. What is bronze?
Bronze is an alloy, which is a homogeneous mixture of two or more metals.
Is copper turing green a physical or chemical change?
It's a chemical change. Copper oxidizes to form copper oxide, which is similar to iron rusting. A color change very often indicates a chemical change.
Is hammered copper a physical change?
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
The melting point of copper is 1083 C is this a chemical change or physical change?
The melting of copper is a physical change because it involves a change in the state of matter from solid to liquid without altering the chemical composition of copper itself.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
When A bronze statue develops a green coating (patina) over time is physical change or chemical?
It is chemical. The copper in bronze turns green when it oxidizes.
How are bronze artifacts made?
by melting tin and copper together and moulding them

What is the bronzes element in the periodic table?
Bronze is an alloy (copper-tin), not a chemical element.
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
Iron rusting is a chemical change since it involves the formation of new substances due to a chemical reaction between iron and oxygen. Copper melting, water freezing, and gas condensing are physical changes where the substances may change state but do not form new chemical compounds.
Why were the tools for the bronze age stronger than those of earlier times?
Answer: The new smelting processes made them stronger -Apex
What is the melting point of aluminium bronze please?
The melting temperature of bronze is between that of tin and copper based on the amount of each in the alloy, usually around 950 degrees C (1750 F). Bronze is an alloy of Copper (90%) and Tin (10%) although other metals are added to change characteristics such as lead, or gold or silver. The actual proportions of copper and tin (or other metals) can vary depending on the intended use of the alloy. Copper melts at approximately 1100 degrees C (2000 degrees F) and pure tin melts much at much lower temperatures -approximately 230 degrees C (450 degrees F). The ratio of these and other metals will determine the actual melting point of the metal you have.
What does it mean when there is physical change?
A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.
When you mix copper and tin you make bronze. No chemical reaction occurs. What is bronze?
Bronze is an alloy, which is a homogeneous mixture of two or more metals.
