The amount of heat required to heat water from 15-20 degrees Celsius in a pool, which is 25 m long

The amount of heat required to heat water from 15-20 degrees Celsius in a pool, which is 25 m long, 10 m wide, 180 cm deep

Let us determine what the volume of water will be equal to, what is in the pool, if from the condition of our problem we know for sure that its dimensions are 25 m, 10 m and 180 cm;

180 cm = 1.8m;

25 * 10 * 1.8 = 450.

Let us determine what, in this case, the mass of water in the pool will be equal to:

water pipes at 15 ° = 999.13 kg / m3;

450 * 999.13 = 449608.5.

Let’s determine how much heat we need in order to heat this mass of water to 20 °:

Q = c * m * (t2 – t1);

arches at 15 ° = 4.187 * 10 ^ 3 J / (kg * C °);

4.187 * 10 ^ 3 * 449608.5 * (20 – 15) ≈ 9.4 * 10 ^ 6.

Answer: 9.4 * 10 ^ 6 J.
