A colored object with a surface area of ​​1 m2 and the temperature is 27 ° C. If the temperature

around the object is 77 ° C, and the value of emissivity = 0.4 and the Stefan-Boltzman (notation o) is = 5.67 xlO '8C, then the heat absorbed is the unity of time

broad unity is
​

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth.
