What are physical and chemical changes?
Physical changes only change the appearance of a substance not its chemical composition. … Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
What means chemical property?
: a property of a substance relating to its chemical reactivity (as the explosive property of nitroglycerin)
What is the property of physical change?
Properties such as shape size colour and state of a substance are called its physical properties. A change in which a substance undergoes a change in its physical properties is called a physical change. A physical change is generally reversible. In such a change no new substance is formed.
What is the difference between physical and chemical weathering quizlet?
The difference is that physical weathering is a process that weathers rock without a chemical reaction or change. Chemical weathering changes the identity of rocks and it involves a chemical reaction or change.
What is the difference between chemical and physical weathering of rock apes?
What is the rock cycle? … physical weathering: the mechanical breakdown of rocks and minerals cause by water wind or variations in temp. chemical weathering: the breakdown of rocks and minerals by chemical reactions the dissolving of chemical elements from rocks or both. How is soil formed?
