Answer: That means that the concrete will increase it temperatures quicly compared with other substances whose specific heat is higher.
Explanation:
Specific heat is the amounf of heat to raise the temperature of 1 gram of substance (or kg depending on the unis used) 1 Celsius degree.
The water, for example, has a high specific heat. That means that you need to add a great amount of heat to raise its temperature, compared with, for exampple the concrete, which is told to have a smaller heat capacity.
You can see that mathematically form the formula for heat released or absorbed from/by a substance:
Q = mass × Specific heat × ΔT
⇒ ΔT = Q / (mass × Specific heat).
So, for the same mass, a certain amount of heat (Q) will result in a bigger ΔT when the specifif heat is smaller.
