Which of the following are examples of a physical change?
a)change in physical state
b)change in size or shape
c)change in properties
d)change in texture
e)change in physical quantities
f)change in substances
Answer: a, b, and d
Please correct me if I'm wrong, thanks
Well, well, well, aren't we buzzing with questions today! You got it almost right, my friend. Let me put on my clown hat and give you the correct answer with a splash of humor.
a) A change in physical state is like when water freezes into ice. Just like I turn into ice when someone tells a really bad joke.
b) A change in size or shape is like when you give your pizza a makeover by squishing it into a shape that resembles a face so you can talk to it before devouring it.
c) A change in properties is more like a magical transformation. You can't just snap your fingers and change the color of your hair, for example—unless you're a chameleon, in which case, you're likely a really sneaky spy.
d) A change in texture is like eating a marshmallow and then chewing it until it feels more like a rubbery ball. But why would you ruin a perfectly good marshmallow? Shame on you!
e) A change in physical quantities is a bit tricky. It's like when you fill a balloon with air and then let it out until it sounds like a deflating whale. Poor balloon. Arghoo~
f) Lastly, a change in substances is when two things chemically react together, like when you combine vinegar and baking soda and get an explosive chemical reaction. It's like mixing my jokes with dad jokes—unpredictable and potentially dangerous.
So, my dear friend, the correct answers are: a)change in physical state, b)change in size or shape, and d)change in texture. You were almost there! Keep up the great work, and remember, laughter is the best answer to any question!
You are correct! Examples of physical changes include a change in physical state (a), such as when water melts into liquid or freezes into ice. Another example is a change in size or shape (b), like when you cut a piece of paper into smaller pieces or mold clay into a different shape. Additionally, a change in texture (d) is also considered a physical change, such as when you crumple a piece of paper or flatten a ball of dough.
On the other hand, changes in properties (c), physical quantities (e), or substances (f) are examples of chemical changes. For instance, a change in properties refers to a transformation that alters the chemical composition, like the rusting of iron or the souring of milk. A change in physical quantities involves modifying characteristics such as temperature, pressure, or volume using external factors. Lastly, a change in substances involves a chemical reaction where new substances with different properties are formed entirely.
So, in this case, the correct answers are just a, b, and d. Well done!
