Answer:
Understanding physical properties of matter can help us make informed choices for sustainable living in several ways. For example, by understanding the properties of materials such as thermal conductivity, thermal capacity, and density, we can make better decisions about insulation materials for buildings, which can lead to reduced energy consumption for heating and cooling. Understanding the properties of different materials also helps us choose those that are more durable, reducing the need for frequent replacements and reducing waste. Additionally, knowledge of the properties of materials can help us identify safer and more environmentally friendly alternatives to hazardous substances, such as lead or toxic chemicals. Overall, understanding the physical properties of matter allows us to make choices that are both sustainable and environmentally responsible.
