Answer:
True
Explanation:
This means the fuel is highly flammable hence it has a low ignition temperature. This, therefore, means it burns fast without putting in a lot of energy to ignite it. Even in cars, therefore, the compression ratios, in engines using these of these fuels, is lesser.
Answer : The amount of in kilojoules released is, -5.53 kJ
Explanation :
Formula used :

where,
q = heat released = ?
c = specific heat of ethanol = 
m = mass of ethanol = 23.4 g
= final temperature = 
= initial temperature = 
Now put all the given values in the above formula, we get:


Therefore, the amount of in kilojoules released is, -5.53 kJ
Answer:
The correct answer is option A. They receive instructions in their DNA.
The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.
<u>Ans: (2) The gas particles have no attractive forces between them.</u>
The kinetic theory explains the behaviour of a hypothetical ideal gas. It explains pressure in terms of the collision of gas particles against the walls of the container which it occupies.
The kinetic theory of gases is based on three main postulates:
1) The collision between gas particles is elastic i.e. no energy is lost or gained
2) The gas particles are treated as point masses i.e. the volume occupied by the gas particles is negligible when compared to the volume of the container
3) There are no attractive or repulsive forces between particles.
