A vector
Temperature is a scalar quantity. It has magnitude but not direction.
Heat capacity is a scalar quantity, as it does not have a direction associated with it. It is a measure of the amount of heat energy required to raise the temperature of a substance by a certain amount.
A vector
scalar, produced by the scalar product of two vector quantities ... Force · Distance
Heat is energy. It and temperature are both scalars.
The main difference between heat and temperature is that temperature measures the average kinetic energy of the particles in a substance, while heat is the transfer of energy between two substances due to a temperature difference. Temperature is a scalar quantity, while heat is a form of energy.
Styrofoam contain a great quantity of air - air is a heat insulator.
The chemical term for heat transfer in a reaction is "enthalpy." Enthalpy is a thermodynamic quantity representing the heat content of a system and is often used to quantify the amount of heat released or absorbed during a chemical reaction.
Temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy from a higher temperature object to a lower temperature object. Temperature is a scalar quantity measured in degrees Celsius or Fahrenheit, while heat is measured in joules or calories.
A scalar quantity has no direction, you cannot talk of north heat, or left heat, or upward heat - they are meaningless. The fact that heat travels in one general direction does not imply a single definite direction - think of a crowd moving along a street - although the crowd may be moving in one direction, the individuals could be moving in any direction within the crowd.
"Vector energy" is pseudoscientific nonsense. Technically, the energy of motion is kinetic energy. However, if the motions are random (the molecules are all just jiggling around any which way, as opposed to all moving in the same direction) then this is experienced overall as heat (thermal energy).
The applications are in transport phenomena, in determining the direction of flow in momentum transport, heat transfer, and mass flux.
