Temperature and absorption

WebAny object can emit and absorb radiation and the power of emission can be represented by the Stefan-Boltzmann law: P = A ϵ σ T 4 In many texts the net power radiated is the difference between the power emitted and the power absorbed: P n e t = A ϵ σ ( T 4 − T s 4) where T s is the temperature of the surroundings. WebBut this absorption has a price: these reactions lower the water’s pH, meaning it’s more acidic. And the ocean has its limits. As temperatures rise, carbon dioxide leaks out of the …
