Ability to melt****
Ability to freeze
Ability to react
Ability to break
3. The physical property that makes metal pots good for cooking is?
Flexibility
electrical conductivity
flammability
heat conductivity****
4. A bucket of water and a cube of ice have different chemical property's
True
False***
Pls check my answers
A
C
D
False
2 is wrong (and I don't need to know the lesson or the unit because know what a chemical property is). Melting is a physical property.
Thank you connexus Virginia. I'm really glad I used that to check my answers! I would have gotten #2 wrong
Sure! Let's go through each question and check your answers:
1. Which of the following is an example of matter?
You answered: Leaves
Correct! Leaves are an example of matter because they are made up of atoms and have mass.
2. Which of the following is an example of a chemical property of matter?
You answered: Ability to melt
I'm sorry, but that is incorrect. The ability to melt is a physical property, not a chemical property. Chemical properties relate to the behavior of a substance when it undergoes a chemical change. An example of a chemical property would be the ability to react.
3. The physical property that makes metal pots good for cooking is?
You answered: Heat conductivity
Great job! Heat conductivity is the correct physical property that makes metal pots good for cooking. Metals have high heat conductivity, meaning they can efficiently transfer heat to the food inside the pot.
4. A bucket of water and a cube of ice have different chemical properties.
You answered: False
That's correct! A bucket of water and a cube of ice have the same chemical properties because they are both water, H2O. The only difference between them is their physical state, with the bucket of water being in its liquid state and the ice cube in its solid state.
