The correct answer is
<span>C) Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half.
In fact, the amount of heat released or absorbed is given by:
</span>

<span>where
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>

is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>
<span>Some minerals might have similar color, but different streaks. Others might have the same streak color, but different colors</span>
Answer:
B
Explanation:
Heat energy of a substace can be calculated using
Q = mcθ
where Q = Heat energy
m =mass
c = specific heat capacity
θ =temperature difference
Temperature difference is final temperature - initial temperature.
So we get,
Q = 1 × 600×(100-20)
= 48000 J
The answer is: To have easy access to a coolant for the reactor.
Hope this helps!:)
