Consider that this resistor is activated when the water reaches a temperature of 25 °C and is deactivated when the temperature reaches 35 °C. Consider the specific heat of water to be 1000 cal⋅kg⁻¹⋅°C⁻¹, 1 cal equal to 4.2 joules, and the density of water equivalent to 1 kg⋅L⁻¹. With the reservoir full, the amount of energy dissipated in this resistor, in watt-hours, is closest to: A) 1.1 × 10³ Wh. B) 2.0 × 10³ Wh. C) 4.7 × 10³ Wh. D) 4.2 × 10⁴ Wh. E) 1.7 × 10⁷ Wh. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of ENEM 2025 PPL solutions: 👉   • ENEM 2025 PPL - Uma nanoantena óptica é um...   Professor Thales Quirino Medeiros ==================
