Question

a 45-centimeter piece of rope is at a temperature of 25°c. then, the ropes thermal energy increases. assume its mass does not change. which is a possible new temperature for the piece of rope? 18°c 31°c

Explanation:

Step1: Understand Thermal Energy and Temperature

Thermal energy increase means the rope gains heat, so its temperature should rise (since mass and substance are constant, more thermal energy → higher temperature).

Step2: Compare Temperatures

Original temp: \(25^\circ\text{C}\). \(18^\circ\text{C}<25^\circ\text{C}\) (decrease), \(31^\circ\text{C}>25^\circ\text{C}\) (increase).

Answer:

\(31^\circ\text{C}\) (assuming the blue box is \(31^\circ\text{C}\) as per the hand icon, since it's the one higher than \(25^\circ\text{C}\) when thermal energy increases).
