The property which allow the metals to be hammered into thin sheets is called malleability. Gold and silver are the best malleable metals. It is due to the property of malleability that metals can be bent to form objects of different shapes by beating with a hammer.
Answer:
Explanation:
Mechanical energy = Gravitational potential energy + kinetic energy
Time Gravitational potential energy kinetic energy Total ME
0 4 0 4
2 2 2 4
4 0 4 4
6 2 2 4
8 4 0 4
and so on .....
We see that total mechanical energy is always 4 which is constant .
So gravitational and kinetic energy changes cyclically but total mechanical energy is constant .
Explanation:
Transpiration: This is the evaporation of liquid water from plants and trees into the Earth's atmosphere. Nearly all water that enters the roots transpires into the atmosphere. Sublimation: This is the process where ice and snow (a solid) changes into a gas without moving through the liquid phase
Answer:
Neutralization reactions
Explanation:
A neutralization reaction is a reaction between an acid and a base. Products of this type of reaction is water and a salt. The pH of the salt product would depend on how strong or weak the base and acid would be when they react with each other. Although the characteristics of bases and acids are practically polar opposites, when combined, they cancel each other our producing a neutralized product.
