Carbon, oxygen, & hydrogen may all be elements found in ethanol, but when separated, they have completely different chemical compounds. They are pure elements where as ethanol is a mixture.
Here we have to choose the property of the liquid, among the given, which the engineer should primary look to use as the fluid of the engine.
The engineer should primarily looked the liquid which have B. low specific heat capacity.
The Specific heat capacity of a substance is equivalent to the heat needed to increase 1⁰ temperature of the unit mass of the substance. Now if the specific heat capacity of the liquid is low then it will need very little amount of energy to transfer the heat.
A. The low thermal conductivity will cause more time to exchange the energy. Which is not required for the engine.
C. There is no relation between the reactivity of the liquid with the use of the same in the engine.
D. The internal energy will also not affect the rate of the cooling or heating of the liquid.
E. The high density also cannot affect the low rate of exchange energy.
Answer:
I'm not 100% percent sure what your question is, but here is what I think you are asking.
Explanation:
The dependent variable is pulse rate and the indepedent variable is the amount of exericse. The dependent variable changes as the independnet variable changes.
Answer:
Ag(s)
Explanation:
Metal atoms are held together by the metallic bond. The metallic bond consists of cations held together by a sea of mobile electrons.
Thus, the crystal of Ag(s) is composed of silver ions held together by a sea of mobile electrons. Electrostatic forces of attraction holds the crystal together.
Matter is never destroyed, nor created. So, this is false.
