Answer:

Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.

While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

Answer: The faster stuff or an object moves, the more energy it has. ... Energy can be transformed from one way to another. Kinetic energy can be told apart from the various forms of potential energy. A demonstration is: toaster transforms electrical energy into thermal energy.

Explanation: An energy transformation is the change of energy from way to another. Energy transformations occur everywhere every second. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, and chemical. Because the law of conservation of energy states that energy is always conserved in the world and simply changes from one form to another, many energy transformations are taking place all the time

Let’s assume that you put a balloon into the freezer. Initially,the balloon had 3.0liters of gas at a pressure of 400kPa and was

EastWind [94]

Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get

P1V1/T1 = P2V2/T2

Then just plug in and solve algebraically.

Hope this helps

Comment on whether each of the following is a homogeneous mixture or a heterogeneous mixture: (a) air in a closed bottle, (b) ai

Colt1911 [192]

Explanation:

A mixture in which there is uniform distribution of solute particles into the solvent is known as a homogeneous mixture.

For example, sugar dissolved in water is a homogeneous mixture.

On the other hand, a mixture in which there is uneven distribution of solute particles into the solvent is known as a heterogeneous mixture.

For example, sand present in water is a heterogeneous mixture.

Comment on given situations will be as follows.

(a) Air in a closed bottle - It is a homogeneous mixture because there will be even distribution of other gases that are present in air.

(b) Air over New York City - It is a heterogeneous mixture because there will be presence of some dust particles, fog or smoke into the air. Distribution of all these particles will be uneven. This will make air over New York City heterogeneous in nature.

How does the law of conservation of mass apply to this reaction:Mg + 2HCl → H2 + MgCl2?

krok68 [10]

The law of conservation of mass applies to every reaction. In this case, you start with 1 Mg, 2 H, and 2CL and end up with the same five only their bonds have been rearranged, or in other words, they are joined up differently.
