Examples of physical properties include color, molecular weight and volume. A chemical property may only be observed by changing the chemical identity of a substance.]]> 2019-01-10 20:40:19 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319469420 6 physical properties dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319471233

A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.]]> 2019-01-10 20:48:03 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319472536 physical change dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319475359 2019-01-10 20:54:12 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319475359 physical change dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476424 2019-01-10 20:56:45 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476424 chemical changes dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476760 2019-01-10 20:57:35 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476760 chemical changes dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476852 2019-01-10 20:57:48 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319476852 dante_santacruz48 https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319477258 2019-01-10 20:58:51 UTC https://padlet.com/dante_santacruz48/9gsj2e199q3c/wish/319477258
