1. Heat is a form of energy that is transferred between objects or systems due to temperature differences. It is typically described as the energy associated with the movement of particles (atoms or molecules) within a substance. Heat flows from hotter objects to colder objects until thermal equilibrium is reached.
On the other hand, cold is not a form of energy. It is the absence or low level of heat energy. Cold is commonly understood as the sensation experienced when heat is removed from the body, but it is actually just a lack of heat.
2. No, all materials do not respond to heat in the same way. Different materials have different thermal properties, such as thermal conductivity and specific heat capacity, which determine how they absorb, retain, and transfer heat.
For example, metals are generally good conductors of heat and can quickly transfer heat from one point to another. Wood, on the other hand, is a poor conductor of heat and does not easily transfer heat.
3. The thermometer laying on the same table in the same room conditions would have a higher temperature reading. The mitten provides insulation and acts as a barrier between the thermometer and the surroundings, reducing the amount of heat transferred to the thermometer. Therefore, the thermometer inside the mitten would have a lower temperature reading compared to the thermometer on the table.
