The common units of temperature are degrees Celsius (°C), degrees Fahrenheit (°F), and Kelvin (K).
No, using paper-like materials for cooking utensils is impractical because they cannot withstand high temperatures, moisture, or repeated use. They would disintegrate, burn, or lose strength, making them unsuitable for cooking purposes.
A cloth tumbler cannot be used to store water because cloth is porous, allowing water to seep through. It lacks the necessary waterproof properties to hold liquids, making it unsuitable for storing water.
No, a cricket ball cannot be used to play tennis because it is too hard, heavy and lacks the required bounce. Tennis balls are lighter, softer and specifically designed to suit the game’s dynamics.
Different materials are used for making sports balls to suit the specific needs of each game, such as durability, bounce, weight, and grip. These factors influence the ball’s performance and player control in different environments.
No, not all lustrous materials are metals. While metals like gold and silver are lustrous, non-metals like diamonds and certain minerals also exhibit luster. Luster is not exclusive to metals but depends on surface properties.
Gases like oxygen and carbon dioxide dissolve in water, allowing aquatic life to survive. The amount of gas that dissolves depends on temperature and pressure, with colder water holding more dissolved gases than warmer water.
Liquids like vinegar dissolve in water because they are polar. However, oil does not dissolve due to its non-polar nature. Honey partially dissolves in water as it contains both water-soluble sugars and other substances.
Yes, all materials share common properties: they have mass, occupy space, and can change state under certain conditions. These fundamental characteristics define matter, regardless of whether the material is solid, liquid, or gas.
