According to NCERT ... physics..
Temperature - a property which determines whether body feels cold or hot to touch ..!

**Temperature is a property which determines the following:**

**1. How much heat a body contains:**
Temperature is a measure of the average kinetic energy of the particles in a substance. When the particles in a substance have higher kinetic energy, the temperature of the substance is higher. The total amount of heat energy in a body is directly related to its temperature. As the temperature increases, the amount of heat energy contained within the body also increases. Conversely, as the temperature decreases, the amount of heat energy decreases.

**2. Whether a body will feel hot or cold to touch:**
The perception of temperature is subjective and depends on various factors, such as the temperature of the body being touched, the temperature of the surrounding environment, and the sensitivity of the individual's skin. When a body has a higher temperature than the surrounding environment, it feels hot to touch. Conversely, when a body has a lower temperature than the surrounding environment, it feels cold to touch. The perception of hot or cold is based on the exchange of heat energy between the body and the surrounding environment.

**3. In which direction heat will flow between two systems:**
Heat always flows from a region of higher temperature to a region of lower temperature. The temperature difference between two systems determines the direction of heat transfer. If two systems are in contact and have different temperatures, heat will flow from the system with higher temperature to the system with lower temperature until thermal equilibrium is reached. This principle is known as the second law of thermodynamics. The temperature gradient determines the rate and direction of heat transfer between systems.

**4. How much total absolute energy a body has:**
Temperature is related to the total absolute energy of a body, but it does not directly determine the total energy. The total energy of a body includes not only its thermal energy (related to temperature) but also other forms of energy, such as potential energy, kinetic energy, and internal energy. Temperature provides information about the average kinetic energy of the particles in a substance, but it does not account for other forms of energy. To determine the total absolute energy of a body, various factors need to be considered, including temperature, mass, and the specific properties of the substance.

In conclusion, temperature is a property that determines the amount of heat a body contains, whether a body feels hot or cold to touch, the direction of heat flow between two systems, and provides information about the average kinetic energy of particles. However, it does not directly determine the total absolute energy of a body, as other forms of energy need to be considered as well.
