PHysical properties are properties that do not involve changes in the molecular level. In this case, malleability and magnetism are physical.
Chemical properties involve changes to the substance at the molecular level or change its identity. In this case, reacting with oxygen and nonflammability is a chemical property.
Hi there!
The energy that is about to or can be released from an object after energy has been transferred to it is called potential energy. In this case, as the diver jumps, potential energy is stored in the board as it bends. The potential energy is then released as kinetic energy when the board springs back up and the diver actually jumps.
Hope this helps!
Answer:
chemical energy is converted to electrical energy in a voltaic cell.
C good thing is that I have a good time at my
Answer:
Differences are listed below:
Explanation:
Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.
Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.
Machinability: Plastic are much more easier to cut through than metal.
Product life: The life span for plastic is longer than of the metals in many applications.
Cost: The cost of plastic raw materials is appreciably less than of the metals.
Heat: Plastic are less heat resistive than metals.
Ultraviolet light can degrade the plastics soon.
Strength: Metal provides more strength than the plastic.
