Part (n) of this question can be understood two ways: the dye can simply be absorbed by the fabric (this is a physical change) or it can react chemically with the fabric (this is a chemical change). (k) mixing water and food coloring - physical (e) slicing potatoes for fries - physical (a) fogging a mirror with your breath - physical The question explicitly uses the concept of burning, so answering this one as both a physical and a chemical change (if asked on a test) would probably garner partial credit.Įxample #6: Label each process as a physical or chemical change: The alcohol must first evaporate, which is a physical change, before it burns (the chemical change). Part (c) actually has a physical process in it. (e) hydrogen burns in chlorine gas - chemical ![]() (d) Chlorine gas liquefies at −35 ☌ under normal pressure - physical (d) A chef making a sauce with brandy is able to burn off the alcohol from the brandy, leaving just the brandy flavoring - chemical (b) hydrofluoric acid attacks glass (used to etch glassware) - chemical (a) Moth balls gradually vaporize in a closet - physical Part (m) of this question can be understood two ways: does 'exposion' means the actual opening up of the container (a bomb, for example) or does it refer to the chemical inside the bomb reacting? The exposion which throws pieces of the bomb about is a physical change, the chemical reacting inside the bomb (which produces the heat & pressure causing the bomb to shatter into pieces) is a chemical change.Įxample #5: Label each process as a physical or chemical change: (c) fermenting of cheese - this one is NOT a physical changeĮxample #4: Which are physical and which are chemical changes? Burning does not include the physical change of evaporation.Įxample #3: Which of the following is NOT a physical change? However, the question is asking about the burning, which is a chemical change. In part (c) there is also a physical change, in that the gasoline must first evaporate before it burns. ![]() (c) burning gasoline in a lawnmower - this one is NOT a physical change Part (d) of this question can be understood two ways: is it asking about the charcoal producing the heat or about the metal grill getting hot? The metal grill getting hot is a physical change, the charcoal reacting with oxygen (which produces the heat) is a chemical change.Įxample #2: Which of the following would NOT be a physical change? (f) a hot glass cracking when placed in cold water - physical (e) autumn leaves changing color - chemical (a) perfume evaporating on your skin - physical ChemTeam Worksheet Answers: Physical and Chemical Changes Worksheet Answers: Physical and Chemical ChangesĮxample #1: Label each process as a physical or chemical change: ![]()
