Final answer:
The provided scenarios relate to the effect of sunlight on heating water and other thermodynamic processes. The question about 'afternoon conditions' lacks context but typically involves more intense sunlight and warmth.
Step-by-step explanation:
The student's question is related to several scenarios of physics and chemistry, particularly focusing on sunlight intensity, polarizing filters, and their impact on water heating as well as other factors affecting reactions and temperature. In particular:
- The intensity of sunlight and the focusing of this light through a lens and polarizers to heat water in a beaker.
- Whether polarizing filters absorb heat.
- The calculation of the final equilibrium state in relation to greenhouse gas absorption.
- The impact of temperature on the Gibbs free energy of reactions and enthalpy (AH) and entropy (AS) as functions of temperature.
To answer the initial question, we would need more context since the actual scenarios represented by cases 'alpha', 'beta', 'gamma' are not provided within the query. However, the nature of the investigations discussed suggests an afternoon scenario might involve higher sunlight intensity and resultant heating effects, potentially involving the investigation of the polarizing filters' heating. The student should consider that afternoon conditions typically involve stronger sunlight and warmer temperatures, affecting the rate of heating and other reaction parameters.
