We usually eat steamed buns, rice and other low-calorie staples. Rice contains 116,000 calories per 100 kilograms. Imagine how low calorie sweet corn is. Each 100 grams of sweet corn contains 86 kilocalories, 3.27 grams of protein, 18.7 grams of carbohydrates, 2 grams of dietary fiber and 1.35 grams of fat.
Each 100 grams of glutinous corn contains 144 kcal of energy, 3.6 grams of protein, 29.6 grams of carbohydrates, 7.4 grams of dietary fiber, 1.8 grams of fat. Comparing the two, we can quickly find that sweet corn is lower in calories than glutinous corn, and people who are in the fat loss period are more suitable for eating sweet corn than glutinous corn.
Heat and internal energy
Heat and internal energy are related like work and mechanical energy. Heat is a measure of the change in an object's internal energy. If two regions have not reached thermal equilibrium, then heat is transferred from the middle, where the temperature is high, to the other, where the temperature is low. Any substance has a certain amount of internal energy, which is related to the disordered motion of the atoms and molecules that make up the substance. When two substances of different temperatures come into thermal contact, they exchange internal energy until they are at the same temperature, i.e., thermal equilibrium is reached. Here, the energy transferred is equal to the heat exchanged.
Many people confuse heat with internal energy. Heat actually refers to the change in internal energy and the work done by the system. Heat describes the change in internal energy, and internal energy is a state quantity, a state function of the system that corresponds to a state point in the system. A full understanding of the difference between heat and internal energy is key to understanding the first law of thermodynamics. In heat transfer, the amount of heat transferred between objects is process-dependent (adiabatic, isothermal, isobaric), i.e., the absorption or excretion of heat must take place 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 as well as a change quantity).
