Due to the presence everywhere of the cosmic background radiation, the minimum possible temperature of a gas in interstellar or intergalactic space is not 0 K but 2.7 K. This implies that a significant fraction of the molecules in space that can be in a low-level excited state may, in fact, be so. Subsequent de-excitation would lead to the emission of radiation that could be detected. Consider a (hypothetical) molecule with just one possible excited state. (a) What would the...

150 grams of boiling water (temperature 100°C, heat capacity 4.2 J/gram/K) are poured into an aluminum pan whose mass is 970 grams and initial temperature 25°C (the heat capacity of aluminum is 0.9 J/gram/K). (a) After a short time, what is the temperature of the water? (b) What simplifying assumptions did you have to make? The thermal energy of the aluminum doesn't change. Energy transfer between the system (water plus pan) and the surroundings was negligible during this time. The...

If the temperature difference DT between an object and it surroundings is not too great, the rate of cooling or warming obeys Newton’s Law of Cooling, d(DT)/dt = – K DT where K is a constant. (a) Why is there a minus sign on the right-hand side of the equation? (b) On what factors does K depend and what are its units? (c) It DTo is the temperature difference at time to, what is the temperature difference at time t...
The wavelength of peak emission from any star is related to the temperature of its photosphere...
The wavelength of peak emission from any star is related to the temperature of its photosphere (i.e., the emitting surface) by Wien’s Law, given by λ = 2,900/T, where λ is the wavelength in micrometers (1 µm = 10-6 m), and T is the temperature of the star in Kelvin (see textbook’s figure 3.27 for help). Answer the following questions using the above equation. 2.1. The most massive star ever observed is a Wolf-Rayet type-star, named R136a1. It is so...
