A swimming pool filled with water has dimensions
of 4.51 m ✕ 10.7 m ✕ 1.60 m. Water
has
density 𝜌 = 1.00 ✕ 103 kg/m3and
specific heat
c = 4186
.
(a)Find the mass (in kg) of water in the pool
kg
(b). Find the thermal energy (in J) required to heat the
pool water from 15.8°C to 26.6°C.
J
(c) Calculate the cost (in dollars) of heating the pool
from 15.8°C to 26.6°C if electrical energy costs
$0.120 per kilowatt-hour.
