The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.
13 lis 2022 · Heat is the quantity of thermal energy that enters or leaves a body. Temperature measures the average translational kinetic energy of the molecules in a body.

Systems are in thermal equilibrium when they have the same temperature. The zeroth law of thermodynamics states that when two systems, A and B , are in thermal equilibrium with each other, and B is in thermal equilibrium with a third system C , then A is also in thermal equilibrium with C .
Notation and units. As a form of energy, heat has the unit joule (J) in the International System of Units (SI). In addition, many applied branches of engineering use other, traditional units, such as the British thermal unit (BTU) and the calorie. The standard unit for the rate of heating is the watt (W), defined as one joule per second.
24 wrz 2024 · Heat, measured in Joules, represents the transfer of thermal energy between objects or systems. Temperature, measured in degrees Celsius, Kelvin, or Fahrenheit, indicates the average kinetic energy of molecules within a substance.
