There are two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.]]> 2017-10-16 15:29:31 UTC https://padlet.com/3060071/sba8nlkyyrgx/wish/197409832 3060071 https://padlet.com/3060071/sba8nlkyyrgx/wish/197411274 Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds]]> 2017-10-16 15:31:49 UTC https://padlet.com/3060071/sba8nlkyyrgx/wish/197411274 3060071 https://padlet.com/3060071/sba8nlkyyrgx/wish/197411792 Chemical changes occur when a substance combines with another to form a new substance, called chemicalsynthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.]]> 2017-10-16 15:32:36 UTC https://padlet.com/3060071/sba8nlkyyrgx/wish/197411792 3060071 https://padlet.com/3060071/sba8nlkyyrgx/wish/197412798 In physics, the law of conservation of energy states that the total energy of an isolated system in a given frame of reference remains constant — it is said to be conserved over time.]]> 2017-10-16 15:34:05 UTC https://padlet.com/3060071/sba8nlkyyrgx/wish/197412798
