What are the hot fruits?

Best answer: Jujube, Hawthorn, Cherry, Pomegranate, Litchi, Green Fruit, Durian, Papaya, Orange and Ginkgo are all hot fruits. Hot, refers to fruits with high calories and high sugar content. Heat refers to the thermal interaction between the system and the outside world when the change of the system state comes from the destruction of thermal equilibrium conditions, that is, from the temperature difference between the system and the outside world. As a result, energy is transferred from a high temperature object to a low temperature object, and the transferred energy is called heat.

The relationship between heat and internal energy is just like the relationship between work and mechanical energy. Heat is a measure of the energy change in an object. If the heat balance between the two areas has not yet been reached, then the heat will be transferred from the place where the temperature is high among them to the other place where the temperature is low. Any substance has a certain amount of internal energy, which is related to the disordered movement of atoms and molecules that make up the substance. When two substances with different temperatures are in thermal contact, they exchange internal energy until the temperatures of both sides are consistent, that is, they reach thermal equilibrium. Here, the amount of energy transferred is equal to the amount of heat exchanged.

Many people confuse heat with internal energy. In fact, heat refers to the change of internal energy and the work done by the system. Describe the variation of internal energy, which is a state quantity, a state function of the system and corresponds to a state point of the system. Fully understanding the difference between heat and internal energy is the key to understanding the first law of thermodynamics. In the process of heat transfer, the heat transferred between objects is related to the process (adiabatic, isothermal and isobaric), that is, the heat absorption or release must be carried out in a certain process. When an object is in a certain state, it cannot be said how much heat it contains (heat is a process quantity and a change quantity).
