Calculate the Cal(kcal) in 1 cup of whole milk: 12 g of carbohydrate, 9 g of fat, and 9 g of protein.
laiz [17]
 Fat: 1 gram = 9 calories    Protein: 1 gram = 4 calories    Carbohydrates: 1 gram = 4 calories    Alcohol: 1 gram = 7 calories"
So, (12 g carbohydrates)*4 Cal=48 Cal; (9 g fat) *9 Cal=81 Cal; (9 g protein)*4 Cal=36 Cal
48 Cal + 81 Cal + 36 Cal = 165 Cal in one glass of milk

Consider a balloon of nitrogen gas and a crystal of sugar sitting on a table at room conditions. Select the appropriate statemen
yKpoI14uk [10]

Answer:

about the same

Explanation:

Thermal energy is constant at a certain temperature in general. The energy is denoted by K_BT

Where,

K_B is the Boltzmann constant

T is the absolute temperature

Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.

Thus,

The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.
