matter in our surroundings

What is matter?

• Sound without mass

• Light without mass

• Energy without mass

• Anything that has mass and takes up space

What are the three forms of matter based on interparticle forces and arrangement of particles?

• Solid, liquid, gas

• Solid, gas, plasma

• Solid, liquid, plasma

• Liquid, gas, plasma

What is a physical property of matter?

• Temperature, pressure, velocity, force

• Taste, sound, weight, volume

• Appearance, colour, odour, density

• Length, time, frequency, energy

What happens to the particles of matter when the temperature increases?

• They vibrate with higher energy
