Question One (5 marks) — Gas laws and atmospheric chemistry a) Consider two planets, Thior and Calistar, a similar distance from the same star. Thior has an atmospheric composition of two unknown gases, X and Y, in an 80:20 ratio (i.e. the atmosphere is 80% gas X and 20% gas Y). The surface temperature of Thior is, on average, 285 K. In contrast, Calistar has the opposite ratio of these same two gases (20% X and 80% Y), and an average surface temperature of 253 K. Using your understanding of greenhouse gases, comment on which gas (X or Y) is more likely to interact with infrared radiation. Furthermore, comment on the internal bonds of each gas and why this would lead to a higher planetary average temperature. (2 marks) b) Further evidence is found to suggest that Thior has an atmospheric pressure twice that of Calistar. Describe what might happen to a 1.00 L balloon on Thior if it was suddenly placed on Calistar. Calculate any changes you would expect, presuming the temperature in each case matches the planetary averages mentioned in part a). (3 marks)
