Physical changes - $100 Which choice is a physical change? COLOR Burning wood OR color COLOR

Physical changes - $200 Why is ice melting a physical change? When it happens the ice is still made water H20 molecules. It doesn’t turn into a new substance.

Physical changes - $300 When we heat metal over a fire it expands when exposed to the flame. Is this a physical or chemical change and why? Physical change because metal does not burn, therefore it stays the same substance when it expands. This makes it physical.

Physical changes - $400 What does solubility mean? How well/if an object dissolves when placed with another substance.

Physical changes - $500 What is a physical change and how is it different than a chemical change? A physical change is a change in a substance that does not involve that substance turning into something new. Chemical changes turn the substance into something new

Chemical changes - $100 Which is a chemical change? Rusting metal Rusting metal on your car Paint cracking and chipping on your car Rusting metal

Chemical changes - $200 When a reaction occurs between two substances, what is the proof that a new substance is forming? Bubbles prove that gases are forming

Chemical changes - $300 List three types of chemical changes/properties. Reactivity Flammability Milk souring rusting

Chemical changes- $400 What is the definition of a chemical change? A change that occurs with a substance that turns it into another substance as a result

Chemical changes - $500 What is electrolysis? Using electricity to separate water into its component parts hydrogen and oxygen.

Conservation of Mass - $100 What is matter? Anything that takes up space

Conservation of mass - $200 Is there anyway to destroy matter? NO

Conservation of mass - $300 If we react vinegar and baking soda, the two substances disappear. What must they turn into based on the law of conservation of mass? Gases

Conservation of mass - $400 What is the law of conservation of mass? Matter cannot be created nor destroyed

Conservation of mass - $500 Explain an example of a reaction using the law of conservation of mass. Answers will vary

Examples - $100 Is melting ice a chemical or physical change? Physical

Examples - $200 What is the ability for something to dissolve called? Solubility

Examples- $300 What is the difference between reactivity and flammability? Reactivity- reacts Flammability- burns something

Examples - $400 List 6 types of physical changes/properties. Color solubility Density hardness Malleability mass Conductivity volume Density shape

Examples - $500 List 4 types of chemical properties/changes Rust Flammability Electrolysis Souring of milk Rotting of food

MISC - $100 What is a sign that a chemical reaction is taking place? bubbles

MISC - $200 What effect does temperature have on rate of reactions? As temperature increases the rate of reaction increases.

MISC - $300 How would you observe if a change was a chemical or physical change? Check to see if the substance turned into a new one or not

MISC - $400 Is melting something a chemical or physical change? Why? Physical change because it does not turn into a new substance when we melt something

MISC - $500 What is the difference between a chemical and physical change? A chemical change is a change that involves the substance turning into a new substance where a physical change is a change that does not change the substance into a new one.
