When a substance undergoes a chemical change, it results in different physical properties as well. ]]> 2017-10-06 14:10:52 UTC https://padlet.com/222068/ten4dsd37iny/wish/194694583 222068 https://padlet.com/222068/ten4dsd37iny/wish/194694885 How it happens: A physical change is any change that alters the form or appearance of a substance but does not change it into another substance.  ]]> 2017-10-06 14:11:25 UTC https://padlet.com/222068/ten4dsd37iny/wish/194694885 222068 https://padlet.com/222068/ten4dsd37iny/wish/195243827 The energy released as the products form is greater than the energy required to break the bonds of the reactants. The energy is usually released as heat. For example some stoves use natural gas. When natural gas burns, it releases heat. This heat is used to cook yo food.  ]]> 2017-10-09 14:28:39 UTC https://padlet.com/222068/ten4dsd37iny/wish/195243827 222068 https://padlet.com/222068/ten4dsd37iny/wish/195607721 More energy is required to to break the bonds of the reactants than is released by the formation of the products. The energy can be absorbed from nearby matter. When energy is absorbed, it causes the surroundings  to become cooler.]]> 2017-10-10 14:11:31 UTC https://padlet.com/222068/ten4dsd37iny/wish/195607721
