Hot milk tea has more calories.
? The kinetic energy of all the molecules in an object in irregular motion, and molecular potential energy the sum of the object is called the internal energy (internal energy), to change the internal energy of the object is work and the heat transfer, and iced milk tea into hot milk tea by the heat transfer, in the process of heat transfer, the internal energy between objects In the process of heat transfer, the amount of internal energy transferred between objects is called heat.
How many calories can you reduce by drinking iced milk tea? How many calories are in a cup of milk tea? The main components of milk tea are: milk + tea + sugar. The calories in a cup of milk tea come mainly from its sugar. The amount of sugar added to milk tea is staggering. A cup of milk tea will have about 55g of sugar, just one cup of milk tea, has exceeded the health red line "50g of sugar per day" standard.
Generally speaking, a cup of 400ml of milk tea contains 180kcal, through the calculation can be learned: the caloric concentration of milk tea = 450kcal/L (different milk tea will be different). Assuming that the calories of milk tea are fully absorbed by the body, then we will grow 50g of fat for every 1L of milk tea we drink on average.
How many calories can iced milk tea reduce? Joule Calorie is also used as a unit of heat, both have different definitions. 1 Joule is defined as: 1N force to make an object move 1m in the direction of the force of the energy required, 1 calorie is defined as: let 1g of water to rise 1 degrees Celsius of the energy required. The conversion of the two is: 1 calorie = 4.182 joules, which means that for every 1L of ice water we drink (assuming 0°C), our body has to produce heat to raise its temperature to body temperature (assuming 36.5°C). Based on the definition of a calorie, we can quickly figure out that the body will burn 36.5 kilocalories in the process.
In this process, we can approximate the specific heat capacity and density of iced milk tea with ice water. Next we can calculate: iced milk tea caloric concentration = 450 kcal / L - 36.5 kcal / L = 413.5 kcal / L. Than the ordinary milk tea per liter to reduce the 4g of fat, but you think that's all. We know that in milk tea stores, the way the clerks turn milk tea into ice is by adding ice cubes. This operation of adding ice actually reduces the concentration of the milk tea. Accordingly, it also reduces the concentration of heat in the milk tea. At the same time also ensure that we drink into the milk tea temperature remains at 0 ℃, assuming that we add ice accounted for 1/5 of the milk tea
By calculating, its calorie is reduced to 324.23 kcal / L, per liter of milk tea is reduced by about 90 kcal calories, equivalent to the reduction of an egg's calorie is a little bit more, according to the summary, and ultimately got a such an equation: the density of the milk tea is about 1g / mL, the density of ice is 0.5 g / mL, the density of ice is 0.5 g / mL, the density of ice is 0.5 g / mL. mL, the density of ice is 0.9g/mL, we can assume that the proportion of ice for a, the volume of milk tea for V, then the equation becomes, according to this equation we can find that when the proportion of ice to a certain extent, we drink milk tea calories are completely offset, through the calculation of the ratio is 92.6%, almost all ice... ...
So hot milk tea is high in calories.
