Question
Energy cannot be created nor destroyed. But it can be transferred between a system and its surroundings. The change in internal energy, delta E, is positive if the system absorbs energy, and it is negative if the system releases energy. (Figure 1) The total change in internal energy is the sum of the heat, q, and work, w: delta E = q + w. Classify the following by the sign of delta E for the system. Drag the appropriate items to their respective bins. If no definitive classify made, drag the item into the bin labeled " Not enough data."Explanation / Answer
Part A. Internal energy sign dE = q+w
Negative
The system expands and the surroundings get hotter
Positive
The system contracts and the surroundings get colder
Not enough data
The system contracts and surrounding gets hotter
The system expands and the surroundings get colder
