To conserve fossil fuels, we can adopt practices like carpooling, reducing energy consumption at home, using energy-efficient appliances, supporting renewable energy sources, and raising awareness about sustainability within our communities for a greener future.
Using natural resources judiciously is crucial to ensure their sustainability. Responsible consumption helps preserve ecosystems, supports biodiversity, and prevents depletion, allowing future generations to benefit from these essential resources for their survival and well-being.
Human-made resources are materials or products created by humans from natural resources to fulfill specific needs. Examples include buildings, machinery, and vehicles, which are crafted using raw materials like metals, wood, and minerals.
Natural resources like water, air, and forests are replenished through cycles like the water cycle, photosynthesis, and nutrient recycling. These processes ensure that resources are renewed, making them sustainable if managed responsibly.
Other examples of gases include nitrogen, which makes up most of the atmosphere; helium, used in balloons; and methane, found in natural gas. These gases play essential roles in our environment and daily lives.
Water exists in three states: solid (ice), liquid (water), and gas (water vapor). We encounter ice in freezers, drink liquid water, and see steam rising when water boils, showcasing its versatility in everyday life.
Yes, we can conclude that the water collected outside the tumbler is solely due to condensation. The cool surface of the tumbler causes moisture from the air to condense, forming droplets on the exterior.
Yes, we can conclude that water is not seeping through the wall of the tumbler. The closed system, with the steel plate, prevents any water from escaping or entering, maintaining the total mass.
I’ve seen similar water droplets on cold beverage cans, especially during summer. In bathrooms after a hot shower, condensation forms on mirrors and tiles. Even on plants, dew appears in the early morning.
