house
Definition
A house is a building that is used for human habitation. It typically has a roof, walls, and a floor, and may also have windows, doors, and a chimney. Houses are often made of wood, brick, or concrete, but they can also be made of other materials, such as stone or metal.
Houses can be found in many different parts of the world, and they come in a variety of shapes and sizes. Some houses are very simple, while others are very complex. Houses can be made to look like anything you can imagine, from a traditional log cabin to a futuristic spaceship.
Houses are important because they provide shelter from the elements. They also provide a place for people to sleep, eat, and store their belongings. Houses can also be a place for people to gather and socialize.

AQA Science Exam Question and Answer
Question:
Explain the concept of thermal insulation in houses and discuss how different materials used in construction contribute to maintaining comfortable indoor temperatures and energy efficiency, considering factors such as conductivity and insulation thickness.
Answer:
Thermal insulation in houses refers to the materials and techniques used to reduce heat transfer between the interior and exterior environments. This plays a crucial role in maintaining comfortable indoor temperatures and enhancing energy efficiency.
Different construction materials possess varying thermal properties. Materials with low thermal conductivity, such as fibreglass, foam, and cellulose, are commonly used as insulation. These materials minimise heat conduction through walls, roofs, and floors. Insulation thickness is also important; thicker insulation layers create more resistance to heat flow.
During cold weather, effective insulation prevents heat from escaping, reducing the need for excessive heating and lowering energy consumption. In hot weather, insulation minimises heat gain from outside, keeping indoor spaces cooler and reducing the need for excessive air conditioning.
Furthermore, proper insulation can also contribute to noise reduction and moisture control within a house.
In conclusion, thermal insulation is a key factor in maintaining indoor comfort and energy efficiency. By understanding the thermal properties of different materials and optimising insulation thickness, homeowners can create energy-efficient homes that are comfortable year-round while minimising energy costs and environmental impact.
