An orange orb has a surface area of 6.1 m2 and its surroundings are at 216°C. The orange orb is absorbing heat via radiation at a rate of 510 W and it is emitting heat via radiation at a rate of 661 W. Determine the emissivity of the orb, the temperature of the orb, & Pnet. ### Latent Heat of Phase ChangesThis table provides information on the latent heat required for phase changes in water:| **Substance** | **Latent Heat (J/kg)** ||------------------|------------------------|| Steam ⇔ Water | 2,260,000 || Ice ⇔ Water | 333,000 |#### Explanation:- **Steam ⇔ Water**: The latent heat required to change steam to water (or vice versa) is 2,260,000 J/kg.- **Ice ⇔ Water**: The latent heat required to change ice to water (or vice versa) is 333,000 J/kg.Latent heat is the amount of heat absorbed or released during a phase change of a substance, without changing its temperature. This concept is crucial in understanding thermal dynamics in substances.
