Answer:
A) Devices that transfer kinetic energy have a source of power that is in motion
Kinetic energy is the energy in motion, as such, a device that transfers kinetic energy transfers the energy the power source has into other energy forms
B) Kerosene does not easily cold start like diesel which can burn after compression
C) The first law of thermodynamics states that energy is conserved and it can neither be created nor destroyed, but can be changed from one form to another.
Therefore, when energy is not available in a given location or body, it cannot be obtained from that body or location
Explanation:
<span>If energy is released, the reaction is exothermic. If energy is absorbed, the reaction is endothermic. Since heat is being absorbed in this reaction (to break down H2O into H2 and O), the reaction is endothermic.</span>

Answer:
ice cream is matter
fear is non matter (it's a feeling not a physical object)
laptop is matter
noise is non matter
wood is matter
hope this helps :)
The P-H bond is polar and the molecule is asymmetric.
Non-polar bonds cannot produce polar molecules and symmetric bonds result in even distribution of charge, so no net charge is observed.
