Physical change A change in which the physical form or state of a substance, but not its composition, is altered. Chemical change A change in which a substance is converted into a different substance with different composition and properties.
The physical changes indicate that there is also a chemical change. Magnesium chloride has been converted to magnesium and chlorine. Iron has been converted to a different substance, rust. Solution: a Not a chemical change, but a physical change simply cooling returns the soup to its original form.
There has been no change in composition, thus this is a physical change, and not a chemical change. The wood cannot be unburned. If there is a chemical change, in which the composition of the substance has been altered, the process cannot be reversed by changing the temperature. Solution: a and c can be reversed with temperature; the dew can evaporate and the ice cream can be refrozen. Solution: a The exhaust is lower in energy than the fuel by an amount of energy equal to that released as the fuel burns.
The fuel has a higher potential energy. The more phlogiston a substance contained; the more easily it burned. Once all the phlogiston was gone, the substance was no longer combustible.
The explanation of combustion must include an explanation of all observable quantities. Their explanation of the mass gain required phlogiston to have a negative mass. The total mass of the reactants and products remained constant. His measurements showed that a gas was involved in the reaction. He called this gas oxygen one of his key discoveries.
The first observation is that the toast has not popped out of the toaster. The next step is a hypothesis tentative explanation to explain the observation. The hypothesis is that the spring mechanism is stuck. Next, there will be a test of the hypothesis. In this case, the test is an additional observation the bread is unchanged. This observation leads to a new hypothesis the toaster is unplugged. Besides, it can find the money for the inspiration and energy to turn this life.
