Answer:
Explanation:
1. Boiling point
The boiling point of a substance especially a fluid, is that temperature at which it turns from liquid to gas. The boiling point of water for example is 100°C, at this temperature, liquid water changes to vapor which a gaseous form of water.
2. decrease
When the size of a sample increases, the surface area of the sample decreases and so also the solubility. Smaller sized samples have a large surface area through which the solvent can readily surround and dissolve a material. Larger sized particles on the other hand have low surface area and dissolves slowly than expected.
3. Wood has low thermal conductivity, and metal has high thermal conductivity.
The thermal conductivity of wood is very low while that of metals is very high. This why metals will conduct heat away from a heat source and a wood will remain unchanged in terms of temperature.
4. Volume
Volume is an extensive property of a matter that depends on the amount of substance present. Volume is the amount of space a substance occupies. The more the substance, the more the space it occupies. This why 20g of water will have a higher volume compared to 15g of water.
5. Solvent
A solvent is a liquid that dissolves other substances. When solvents dissolves other substances, they form a solution.
Answer:
A net force acting on an object will change its motion. This means that a net force will change the kinetic energy of an object. The greater the force, the greater the change in motion and the kinetic energy of the object. Objects moving at a constant speed will have a constant kinetic energy.
Answer:
Frequency
Explanation:
It’s kinda self-explanatory but bascially speed=wavelength times frequency
Answer:
The physical body of human work accosting to Action-Reaction law.
Explanation:
The rule of action-reaction state that an equivalent and reverse reaction occurs with any action. If one entity imposes force on a second entity, the second responds by exerting an equivalent force on first entity in the same direction.
