The process of a liquid becoming a gas is called boiling (or vapourization) and the process of a solid becoming a liquid is called melting.

Vaporization is the process of converting a liquid into a gas. It is also called evaporation. Since we know that the particles of a gas are moving faster than those of a liquid, an input of energy must be required for a liquid to become a gas.

Melting is a physical process that results in the phase transition of a substance from a solid to a liquid. During melting, the energy goes exclusively to changing the phase of a substance; it does not go into changing the temperature of a substance. Hence melting is an isothermal process because a substance stays at the same temperature.

Example 1: Industrially, salt is recovered from seawater by the process of vaporization. Wet clothes are dried up due to the process of vaporization. The process is used in many industrial processes for separating the components of a mixture.

Example 2: Ice to water - Ice melts back into the water when it is left out at temperatures above the freezing point of 32 degrees. Rocks to lava - Rocks in volcanoes can be heated until they are molten lava. Metal to molten liquid - Metals such as steel and bronze can be molten down.

The answer to the multiple choice question is 70 kilocalories provided by 10 grams of pure alcohol.

Alcohol is a type of macronutrient that provides energy to the body. It is considered the fourth macronutrient, besides carbohydrates, proteins, and fats. Alcohol is broken down into acetaldehyde and then into acetate, which is converted into energy in the body.

One gram of alcohol provides 7 kilocalories of energy, which is almost double the amount provided by carbohydrates and proteins. The energy derived from alcohol is not used as efficiently by the body as energy derived from other macronutrients, such as carbohydrates, proteins, and fats. This is because the energy derived from alcohol is quickly metabolized by the liver, leading to a temporary increase in energy but also making the body more prone to energy crashes.

Therefore, while alcohol does provide energy to the body, it is important to consume it in moderation to avoid negative health effects.

Salts and sugars work to preserve foods by creating a hypertonic environment. Option A is the correct answer.

In a hypertonic solution, the concentration of solutes outside of cells is higher than that of solutes inside cells. A cell's water is soaked out as a result, and it shrivels up. Option A is the correct answer.

Foods are preserved by salts and sugars by fostering a hypertonic environment. Salts have the power to dry food by drawing water out of it. The salted food is protected by the dryness, which also stops the formation of mold and other infections. By halting the growth of microorganisms, especially foodborne diseases like salmonella, salt protects food. Inhibiting microbial development, sugar generates a hypertonic environment that soaks water out of the meal.

The statement "Even though the full oxidation of glucose is exergonic, some of the reactions in glycolysis are endergonic" is a TRUE statement.

Glycolysis is the metabolic pathway of reactions that convert glucose into pyruvate (in the presence of oxygen) or lactate (in the absence of oxygen). There are ten sequences of reactions in it catalyzed by enzymes.

The overall reactions of glycolysis are exergonic, which means energy is released into its surroundings, However, some of the reactions within glycolysis absorb energy instead of releasing energy, making them endergonic reactions. One of them is the second reaction in glycolysis, where isomerase catalyzes the isomerization of G-6-P to F-6-P.

The commercial preparation's enzyme concentration is 500 [E]T.

Let X represent the enzyme concentration in the prepared product.

Step 1: Initial dilution: A commercial product in the amount of 0.100 mL was diluted to a final volume of 25.0 mL. This final solution will be known as solution 1.

Utilizing the formula C1V1 (commercial preparation) = C2V2 (solution 1)

Alternatively, X 0.100 mL = C2 25.0 mL

Alternatively, C2 = (X x 0.100 mL) / (25.0 mL) = 0.004X

Consequently, solution 1's enzyme concentration is 0.004X.

Step 2: Second dilution: The substrate and solution 1 were combined in a volume of 1.0 mL.

As a result, the reaction mixture's total volume (dilution) is equal to 1.0 mL plus 1.0 mL.

Prepare a 0.5% solution (0.5 g in 100 ml) initially, then dilutions of 0.25, 0.1, 0.025, and 0.05% to respective concentrations of the half, one-fifth, one-twentieth, and one-tenth. For example, to ten times dilution and a concentration of 0.05%, add 9 ml water to 1 ml of the stock solution.

The combination of light weight nuclei into heavier nuclei is called nuclear fusion.

An example of nuclear fusion is four hydrogen nuclei combining to form a helium nucleus. This process releases a large amount of energy in the form of light and heat.

The total mass of the resulting helium nucleus is slightly less than the combined masses of the four hydrogen nuclei.

This difference in mass is converted into energy according to Einstein's famous equation E=mc².

The energy released by nuclear fusion is what powers stars, including our own Sun.

Nuclear fusion is a process by which multiple atomic nuclei join together to form a heavier nucleus with the release of energy.

For example, the fusion of two hydrogen nuclei into a helium nucleus is shown below:2H → He + energyIn the case of hydrogen fusion, the released energy is in the form of light and heat, which are the energy sources for stars like the Sun.

The process of nuclear fusion is the opposite of nuclear fission, in which a heavier nucleus is split into two or more lighter nuclei with the release of energy.

Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
