Whether the average surface temperature of earth has been increasing over the past 150 years or not.
Answer to Problem 1CQ
Yes. The average surface temperature of earth has been increasing over the past 150 years.
Explanation of Solution
From the graph given in the question, it can be observed that the average surface temperature of earth sees a steady increase after the year 1960. Before 1960, it can be seen that the average surface temperature is almost the same.
The increase in the average surface temperature of earth can be attributed to the increase in global warming. This is caused due to the significant increase in the levels of carbon di oxide in the atmosphere.
Conclusion:
Yes. The average surface temperature of earth has been increasing over the past 150 years.

- A metal ball, which has a surface area of 175 cm2, is heated in a furnace to 678 oC. a)State the value of temperature in the correct SI units. State your answer as a whole number (and use this value as a whole number, if needed in subsequent calculations). b)State the area in correct SI units. Give your answer in Scientific notation using E for x10x., e.g. you would enter 3.21x106 as 3.21E6. Make sure you have 3 significant figures in the first part of the answer and use this value to this degree of accuracy, if needed in subsequent calculations.Note that Numbas will mark equivalent answers as correct e.g. if 3.21E6 was the correct answer then 32.1E5 or 321E4 etc. would also be marked correct. c)If the emissivity of the metal ball is 0.7, at what rate does it radiate energy?
