Heat is the total energy of all particles in a substance, while temperature is the average kinetic energy of those particles. Heat depends on mass, while temperature does not.
Radiation is the transfer of heat through electromagnetic waves. It doesn’t require a medium, meaning heat can travel through a vacuum, like from the Sun to Earth.
Heat transfer occurs through conduction, convection, and radiation. These processes involve the movement of thermal energy from a hotter area to a cooler one.
The boiling point of water is 100°C or 212°F at standard atmospheric pressure. It is used as a reference point in temperature scales and calibrating thermometers.
The Celsius scale is a temperature scale where water freezes at 0°C and boils at 100°C. It is commonly used in most countries around the world.
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.
Objects can be classified into groups like plastic, metal, glass, and paper. Each material’s properties, such as durability or flexibility, relate to its function—plastics are used for containers, metals for tools and glass for windows.
Material X is likely a soluble, rigid substance like salt, while material Y is a soft, insoluble substance like clay. X dissolves in water, whereas Y remains unchanged, reflecting its different properties.
For food waste, use plastic containers for durability and ease of cleaning. For broken glass, use sturdy, puncture-resistant containers to avoid accidents. For wastepaper, use paper or cardboard bins for easy recycling.
