Statement IIt is a common observation that if we place a glass of ice-water on a table at room temperature, the ice-water will get warmer.
Statement IIHeat is energy that flows between a system and its environment because of temperature difference between them.
General SciencePhysics
- ABoth the statements are individually true and Statement II is the correct explanation of Statement I
- BBoth the statements are individually true but Statement II is not the correct explanation of Statement I
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Explanation
Ice-water placed at room temperature does warm up because its surroundings are hotter, so statement I is true. Heat is energy transferred between a system and its environment due to a temperature difference, which is precisely why the ice-water gains energy and warms, so statement II is true and correctly explains statement I. Hence A.
