1. Heat is a form of energy that is transferred from one object to another due to a difference in temperature. It typically causes an increase in the internal energy of an object, resulting in a rise in temperature.

Cold, on the other hand, is the absence or lack of heat energy. It is often associated with a decrease in temperature and the reduction of molecular activity.

2. No, not all materials respond to heat in the same way. Different substances have different degrees of thermal conductivity, which determines how easily they conduct or transfer heat. For example, metals like copper are good conductors of heat, while materials like wood or plastic are poor conductors.

3. The thermometer laying on the table in the same room conditions will have a higher temperature reading. The mitten acts as insulation, preventing the transfer of heat from the surrounding air to the thermometer. Therefore, the thermometer inside the mitten will be protected from the cold and will not measure the actual room temperature accurately.
