why temperature is important in changing the state of matter?
Answer (1)
Temperature is important in changing the state of matter because it directly affects the energy of the particles in a substance. Here's how:1. Particle MovementTemperature is a measure of the average kinetic energy of particles.When the temperature increases, particles move faster.When the temperature decreases, particles move slower.2. Breaking or Forming Intermolecular ForcesIn order for a substance to change state (e.g., solid to liquid, liquid to gas), the forces between particles must be broken or formed.Melting (solid → liquid) and boiling (liquid → gas) require adding heat to break these bonds.Freezing (liquid → solid) and condensation (gas → liquid) require removing heat to allow bonds to form.Examples:Ice melting: When you heat ice, its temperature rises until the molecules have enough energy to break free from their fixed positions and become liquid water.Water boiling: At 100°C (at sea level), water molecules have enough energy to escape as gas (steam).Summary: Temperature controls the energy level of particles, which determines whether they stay together (solid or liquid) or move freely (gas). This is why it’s a key factor in changing the state of matter.
