in which direction does heat tend to flow?prove it with an activity
Answers
Explanation:
Explanation:Heat within the solid will flow from hot to cold. It will cheerfully flow downward if it is cooler down there. Your intuition about heat rising is probably due to the fact that heated air does rise since it is less dense than cold air, for example in a hot-air balloon or thermal convection currents.

Explanation:
Heat is the flow of thermal energy from a warmer object to a cooler object. Heat will continue to flow from the warmer object to the cooler object...
How is Heat Transferred?
The Second Law of Thermodynamics states that heat will always move from a hot object to a cooler one. Heat transfer is the movement of thermal energy as it transfers from one object to another or between an object and it’s surroundings. Thermal energy will naturally work towards a state of balance or equilibrium. This is known as thermal equilibrium, where two objects or an object and it’s surroundings achieve the same level of heat energy (thermal energy).
Keep in mind the greater the difference in temperature the more rapid the transfer of heat. The Mpemba Effect is a great way to explore this principle in water.
What Is The Difference Between Heat And Temperature?
It’s important not to confuse Heat and Temperature. Heat refers to the energy present in the molecules of an object (picture how fast those molecules are moving). Heat is affected by the speed of the particles, the number of particles (including their size or mass), and the type of particles. Temperature is a measure of the average kinetic energy of the molecules in an object and is not affected by the number or size of the molecules. Heat and temperature are directly related to each other, but not the same thing.
Picture a steaming mug of coffee, now picture a bathtub filled with the same steaming coffee. The temperature is the same, but the thermal energy is higher in the tub because there is more coffee.
In a nutshell, heat is energy. Temperature is a measurement of that energy.
So with these heat transfer projects we are exploring the transfer of energy, with temperature being a common method of measurement and quantification of the results.
