There are two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.]]> 2017-10-16 16:37:35 UTC https://padlet.com/304807/65ngwoza93y4/wish/197451032 304807 https://padlet.com/304807/65ngwoza93y4/wish/197451033 the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.]]> 2017-10-16 16:37:35 UTC https://padlet.com/304807/65ngwoza93y4/wish/197451033 304807 https://padlet.com/304807/65ngwoza93y4/wish/197451576 the strength and vitality required for sustained physical or mental activity.]]> 2017-10-16 16:38:34 UTC https://padlet.com/304807/65ngwoza93y4/wish/197451576 304807 https://padlet.com/304807/65ngwoza93y4/wish/197451754 energy that a body possesses by virtue of being in motion.]]> 2017-10-16 16:38:52 UTC https://padlet.com/304807/65ngwoza93y4/wish/197451754 304807 https://padlet.com/304807/65ngwoza93y4/wish/197452591 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 16:40:17 UTC https://padlet.com/304807/65ngwoza93y4/wish/197452591 304807 https://padlet.com/304807/65ngwoza93y4/wish/197453326 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 16:41:39 UTC https://padlet.com/304807/65ngwoza93y4/wish/197453326
