Answer:
Temperature, the average kinetic energy of particles, tells you how warm something is. Thermal energy, the total kinetic energy of the particles, tells you the extent to which a substance or object can transfer heat or make something else warmer. If an object's temperature increases, its thermal energy increases also.
Difference Between Temperature and Thermal Energy
a. Definition
Temperature: The average kinetic energy of the structural elements of a system (atoms, molecules, charged particles) is called temperature.
Thermal energy: The total kinetic energy of the structural elements of a system is called thermal energy.
b. Values
Temperature: The temperature can be positive and negative.
Thermal energy: The thermal energy always has positive values.
c. Units of measurement
Temperature: The temperature is measured in Celsius, Kelvin, and Fahrenheit.
Thermal energy: The thermal energy is measured in Joule and Calorie.
d. Quantitative dependence
Temperature: The temperature does not depend on the quantity of the substance – it is related to the average kinetic energy of the particles.
Thermal energy: The thermal energy depends on the quantity of the substance – it is related to the total kinetic energy of the particles.
2. The temperature on the Kelvin scale is bigger because the number 273 is always added to the Celcius temperature
3. There’s no really direct connection, however:
The thermal energy of the object is the kinetic energy of the individual molecules that make it up. The more fast-moving molecules inside it, the hotter it is.
When a moving object collides with something, some of the kinetic energy of the object turns into thermal energy. Warming something by rubbing it is an example of this.
4. For a thermometer that is liquid confined in a tube, as the temperature increases, the molecules of the liquid move faster, and the liquid expands. The amount of expansion is related to the increase in temperature.
