Important Questions from Matter in Our Surroundings
Which of the following properties belong to solids?
Show answer
Fixed shape, Fixed volume, Particles are closely packed
Solids have a fixed shape and fixed volume because their particles are closely packed and held together by strong forces of attraction. They cannot flow easily like liquids and are not highly compressible like gases.
Which factors affect the rate of evaporation?
Show answer
Surface area, Temperature, Wind speed, Humidity
The rate of evaporation increases with increase in surface area, temperature, and wind speed, but decreases with increase in humidity. The color of the liquid does not significantly affect evaporation rate.
The temperature at which a solid changes to liquid is called:
Show answer
Melting point
The melting point is the temperature at which a solid changes to liquid at atmospheric pressure. For ice, this is 0°C or 273 K. Boiling point is for liquid to gas conversion, and freezing point is for liquid to solid conversion.
Which state of matter has particles that are:
Show answer
Most closely packed in solids, Freely moving in gases, Can slide over each other in liquids, Have maximum kinetic energy in gases
In solids, particles are most closely packed with least kinetic energy. In liquids, particles can slide over each other with intermediate kinetic energy. In gases, particles move freely with maximum kinetic energy and are farthest apart.
