What is the relationship between the speed of particles and the density of a substance?
What is the relationship between the speed of particles and the density of a substance?
- There is no relationship between the speed of particles and the density of a substance.
- As the speed of particles increases, the substance becomes more dense.
- As the speed of particles increases, the density of the substance remains constant.
- As the speed of particles increases, the substance becomes less dense. (correct)
In what order does density usually increase from gas to solid?
In what order does density usually increase from gas to solid?
- Solid > Liquid > Gas (correct)
- Gas > Liquid > Solid
- Solid > Gas > Liquid
- Liquid > Gas > Solid
Why is ice less dense than liquid water?
Why is ice less dense than liquid water?
- Ice particles have higher speed and spread out more, making it less dense.
- Ice particles have the same speed as liquid water particles, but are more spread out, making it less dense.
- Ice particles have lower speed and spread out less, making it less dense.
- Ice particles form a special lattice structure, making it less dense. (correct)
