Nuclear power plants use a fission reaction of uranium to generate heat to power a generator. A fission reaction is a chain reac

tion that continues to build and create more heat. How is the chain reaction controlled?
A.
The amount of uranium fuel can be reduced to slow the chain reaction down.
B.
The plant uses control rods that can be inserted into the reaction vessel to control the reaction.
C.
Water is added to the reaction to the reaction vessel to cool it down and slow the chain reaction.
D.
The extra heat that is created from the chain reaction is released into the air and keeps the reaction under control.

ANSWER
B.

Explanation : it’s B because the control rods used are usually made of boron which boron is a non fissile material hence won’t undergo fission when bombarded or collided with neutrons.

A gas at 928 kpa, 129 C occupies a volume of 569 L. Calculate the volume at 319 kpa and<br> 32 C.
lisabon 2012 [21]

Answer:

1255.4L

Explanation:

Given parameters:

P₁  = 928kpa

T₁  = 129°C

V₁  = 569L

P₂ = 319kpa

T₂  = 32°C

Unknown:

V₂  = ?

Solution:

The combined gas law application to this problem can help us solve it. It is mathematically expressed as;

           \frac{P_{1} V_{1} }{T_{1} }   = \frac{P_{2} V_{2} }{T_{2} }

P, V and T are pressure, volume and temperature

where 1 and 2 are initial and final states.

Now,

 take the units to the appropriate ones;

             kpa to atm,  °C to K

P₂ = 319kpa in atm gives 3.15atm

P₁  = 928kpa gives 9.16atm

T₂  = 32°C gives 273 + 32  = 305K

T₁  = 129°C gives 129 + 273  = 402K

Input the values in the equation and solve for V₂;

        \frac{9.16  x 569}{402}   = \frac{3.15 x V_{2} }{305}

       V₂   = 1255.4L

How to compare and contrast a solution of hydrogen chloriide gas in water and toluene?
Airida [17]
<span>The solute is the substance that is being dissolved while the solvent is the base that the solute is bring dissolved in. For example, in salt water, salt would be the solute that dissolves into the water, and the water is the solvent that the salt is being dissolved in.</span>

1. when the ball is just starting to fall, it has high potential but low kinetic energy. when it hits the floor, it has high kinetic but low potential energy
2. heat energy
3. reflective-transparent would be best, as they can reflect some light while let other light through, reflective-opaque would be useless in any circumstances because no light at all would be able to get through
