Heat flows spontaneously from hot objects to cold objects. Temperature is related to the average kinetic energy of the particles in an object due to their random motions through space.
Q. What are two differences between heat and temperature?
Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

Q. How heat flows from colder temperature to higher temperature?
According to the rules of classical thermodynamics, the flow of heat between two thermally connected objects with different temperatures is determined by Fourier’s law of heat conduction, stating that the rate of heat flow between these objects increases with growing temperature difference, and, more generally, by the …
Q. What determines the direction of heat flow?
What determines the direction of heat flow? Heat energy is the energy which transfers from hot object to cold object. So the direction of heat flow only depends on the temperature change. Therefore, the temperature determines the direction of heat flow.
Q. How the temperature is affected by the movement of particles in a medium?
Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
Q. Is there a hottest possible temperature?
As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032 K.). This is the highest temperature that we know of according to the standard model of particle physics, which is the physics that underlies and governs our universe. This is known as Planck Temperature.
