Item NG046004: The air inside a glove will be at the same temperature as the air outside the glove throughout the day because the glove and the air inside of it started out at the same temperature as the air outside the glove and no thermal energy was transferred between them.
A student wants to know if a glove can transfer energy to an object placed inside of it. To answer his question, he places one thermometer inside a glove and leaves another thermometer outside the glove. Then the student records the temperature of the air inside and outside the glove. He finds that the glove and the air inside the glove are the same temperature as the air outside the glove.
A few hours later, the student checks the thermometers again. He finds that the temperature of the air outside the glove is the same as it was earlier. Will the air inside the glove be warmer, colder, or the same temperature as the air outside the glove and what will that tell him about energy transfer? (Assume that the temperature of the room does not change.)
- The air inside the glove will be warmer than the air outside the glove because gloves warm things by transferring energy to them.
- The air inside the glove will be colder than the air outside the glove because the glove prevents the air outside the glove from transferring energy to the air inside the glove.
- The air inside the glove will be at the same temperature as the air outside the glove because no energy is transferred between objects at the same temperature.
- It depends on what material the glove is made of because some materials can transfer energy and other materials cannot.
