Which action causes breakers?

Chemistry
2 answers:
4vir4ik [10]3 years ago
8 0

Answer:

The answer is when the waves meet the shore and cause the crest to spill over the trough. This activity creates a back and forth movement of the sand which causes them to settle at a certain area under below the water. Eventually the collected sand piles up wide and tall enough that it is able to break the incoming waves.

The lower the ignition temperature, better the fuel. True or false?Why?
Aleksandr [31]

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.

How much energy in kilojoules is released when 23.4 g of ethanol vapor at 83.0 ∘C is cooled to -15.0 ∘C ?
slamgirl [31]

Answer : The amount of in kilojoules released is, -5.53 kJ

Explanation :

Formula used :

q=m\times c\times (T_{final}-T_{initial})

where,

q = heat released = ?

c = specific heat of ethanol = 2.41J/g^oC

m = mass of ethanol = 23.4 g

T_{final} = final temperature = -15.0^oC

T_{initial} = initial temperature = 83.0^oC

Now put all the given values in the above formula, we get:

q=23.4g\times 2.41J/g^oC\times (-15.0-83.0)^oC

q=-5526.612J=-5.53\times 10^3J=-5.53kJ

Therefore, the amount of in kilojoules released is, -5.53 kJ

15 Which statement describes the particles of an ideal gas, based on the kinetic molecular theory?
serg [7]

<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.
