You need to find the mass of water in the pool.
Find the volume (10 x 4 x 3) = 120 m3
Water has a density of 1000g/m3,so 120 m3 = 120 x 1000 = 120 000 kg
[delta]H = 4.187 x 120 000 x 3.4 (and the units will be kJ)
You then use the heat of combustion knowing that each mole of methane
releases 891 kJ of heat so if you divide 891 into the previous answer,
you will get the number of moles of CH4
One Celsius degree is the same size as one Kelvin. Each of them is the size of 1.8 Fahrenheit degrees.
I think the correct answer from the choices listed above is option B. The very high voltage needed to create a spark across the spark plug is produced at the transformer's secondary winding. <span>The secondary coil is engulfed by a powerful and changing magnetic field. This field induces a current in the coils -- a very high-voltage current.</span>
The answer is <em>Compressional Stress
</em>
In geology, stress<span> is the force per unit area that is placed on a rock. ... This is called confining </span>stress<span>. Compression squeezes rocks together, </span>causing<span> rocks to fold or fracture (break). Compression is the most common </span>stress<span> at </span>convergent plate boundaries<span>.
I hope this helped!! Have a great day :D</span>
