The use of properties of matter in everyday life?

Answer 1

1. Transporting logs

· Logs are transported from the forest through rivers to the sawmill

· Logs float because less denser than water

2. Hot air balloon

· It rises in the air when the hot air in the balloon isless dense than the surrounding air

· Hence, it can float or sink in water

4. A raft

· A raft is made of bamboo or logs

· A rat floats because bamboo or logs are less dense than water

Answer 2

Properties of matter play a role in everyday life in various ways. For example, our understanding of thermal conductivity helps us choose appropriate materials for cooking utensils. Understanding density helps us determine if an object will float or sink in water. Additionally, knowledge of solubility guides us in mixing ingredients for cooking or cleaning.

Answer 3

Anything that has weight and occupies space are called matter. Everything present on earth is matter except the feelings and thoughts one possesses.
