Thank you so much I got a 100!
Sure, I can help you check your answers and explain why each option is correct or incorrect.
1. Which of the following is an example of matter?
A. leaves
B. shadow
C. light from the sun
D. sound
Correct answer: A. leaves.
Explanation: Matter refers to anything that takes up space and has mass. Leaves are physical substances that have both volume (take up space) and mass, so they are an example of matter. Shadows, light, and sound are not examples of matter, as they do not have mass or take up physical space.
2. Which of the following is an example of a chemical property of matter?
A. ability to melt
B. ability to freeze
C. ability to react
D. ability to break
Correct answer: C. ability to react.
Explanation: Chemical properties refer to the behavior of a substance when undergoing a chemical change or reaction. The ability to react is a chemical property because it describes how a substance interacts with other substances to form new substances. Melting, freezing, and breaking are physical properties that describe how a substance reacts under certain conditions, but they do not involve a chemical change or reaction.
3. The physical property to use metal pots good for cooking is _____?
A. flexibility
B. electrical conductivity
C. flammability
D. heat conductivity
Correct answer: D. heat conductivity.
Explanation: Heat conductivity is a physical property that describes how well a material can transfer heat. Metal pots are good for cooking because they have high heat conductivity, allowing heat to spread evenly throughout the pot and cook food efficiently. Flexibility, electrical conductivity, and flammability are not necessarily relevant properties when considering the suitability of metal pots for cooking.
