Answer:
356 000 J
Explanation:
Total Energy released
= Energy released when water cools to 0 + Energy released when water is converted to ice at 0
= mcT + ml
= (0.5)(4200)(90-0) + (0.5)(334 000)
= 189 000 J + 167 000 J
= <u>3</u><u>5</u><u>6</u><u> </u><u>0</u><u>0</u><u>0</u><u> </u><u>J</u>
Thermal energy measures the total kinetic energy of the particles in a substance. The greater the motion of particles, the higher a substance's temperature and thermal energy. A substance's total thermal energy depends on its temperature, number of atoms, and physical state.
