Why do waves travel faster through solid and slowest through a gas?
Because gas is less denser, and the chances that collisions between particles (collisions are wawes) will occur are much smaller than in solids.
Which state of matter would generally be the best material for transmitting sound?
Solid - since the molecules are the closest together more collisions and vibrations occur in the matter.
How does a bouncing ball differ from a vehicle hitting a solid object?
The vehicle is not made of rubber -- it crumples rather than bouncing- it does return to its old shape when compressed.
Is a pencil a solid liquid or gas?
A pencil is a solid object.
How does increasing the surface area of a solid reactant affect the energy of molecular collisions?
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
Can only solid objects exert forces?
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
How do you know if an object is solid?
A solid object is something you can touch and feel. If you can not touch or feel something it is not solid.
The transfer of thermal energy by molecular and electronic collisions with a substance especially a solid?
Conduction.
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
What is meant by rigid and solid?
An object which is rigid resists bending and flexing. An object which is solid is not hollow.
What is a sentence for the word solid?
That rock is a solid object.
Is pencil a solid or a gas?
A pencil is a solid object.
