Answers:
G. -; H. -; I. +
Step-by-step explanation:
ΔE = q + w
Anything going into the system is positive (+), and anything leaving the system is negative (-).
G. Cooling with expansion
q: Heat is leaving; q is -
w: The system is doing work on the surroundings. Energy is leaving the system. w is -.
ΔE is -.
H. Heating a little, expanding a lot
q: Heat is entering; q is +.
w: The system is doing work on the surroundings. Energy is leaving the system. w is -.
However, the expansion work is the major factor.
ΔE ≈ w. ΔE is -.
I. Endothermic, no expansion
q: Heat is entering; q is +.
w: No expansion. w = 0.
ΔE = q. ΔE is +.
Explanation:The scientific inquiry process is the process in which scientists or researchers find an explanation for any natural world phenomena with logic and evidence collected by the systemic method or work.
The scientific inquiry process begins with a question or thinking (observation) for any natural phenomena like why freshwater has low albedo where ice has a high albedo percentage.
