What is the movement of particles at low temperature?
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.
How do temperature and pressure affect which state of matter a substance is in?
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). Decreasing pressure can cause it to vaporize. For some types of rock, decreasing pressure can also cause them to melt.
What is the effect of temperature in the interconversion of state of matter?
Interconversion of States of Matter
| Boiling | Evaporation |
|---|---|
| It takes place at specific temperature called the boiling point of the liquid. | It takes place at any temperature. |
| The temperature of the liquid remains constant during boiling process. | It causes cooling i.e the substance becomes cool due to evaporation. |
What is the role of kinetic energy during interconversion of states?
With the increase in temperature, the kinetic energy increases. This results in the conversion of the state of matter from solid to liquid. When more heat is provided, the liquid changes to the gas.
What are the applications of interconversion of state of matter?
The uses of interconvesion of matter are – . Water is converted into steam by heating . Steam is ysed to run turbines and to generate electricity.
What factors bring about change in matter?
Physical changes are caused by forces like motion, temperature, and pressure. Chemical changes happen on a much smaller level. Most of these changes between molecules are unseen. Factors that affect the rate of chemical changes include: temperature, concentration, surface area, inhibitors, and catalysts.
