Concept explainers
A
Interpretation : The temperature of the rubber band on stretching needs to be commented.
Concept Introduction : Temperature is a physical quantity which manifests the thermal energy present in the matter or object.
B
Interpretation : The stretching process either it is endothermic or exothermic needs to be explained.
Concept Introduction : Endothermic process absorbs energy from the surroundings whereas exothermic release the energy in surroundings.
C
Interpretation : The results need to be explained in terms of intermolecular forces.
Concept Introduction : Intermolecular forces are the type of forces between molecules and the other type of molecules.
D
Interpretation : The sign of
Concept Introduction : The signs of the
E
Interpretation : The molecular explanation of the sign of the
Concept Introduction : Intermolecular forces are the type of forces between molecules and the other type of molecules.
