Answer: These are the methods of energy transformation

Explanation:

1- Heat transfer :- it is the movement of heat from one substance or material to another. Heat transfer takes place through three principals- Conduction, Radiation, Convection.2- Conduction :- it is the process by which heat energy is transmitted through collisions between neighboring atoms and molecules.3- Convection :- it is the transfer of heat between two bodies by currents of moving gas or fluids.4- Radiation :- it is energy that comes from source and travels through space at the speed of light.

Explanation: hope this helps

1. Heat transfer describes the flow of heat (thermal energy) due to temperature differences and the subsequent temperature distribution and changes.

2. Conduction describes the process by which heat energy is transmitted through collisions between neighbouring atoms or molecules. (Basically, it happens more readily in solids and liquids, where the particles are closer together)

3. Convection describes the process by which heat is transferred by the movement of a heated fluid such as air or water.

4. Radiation describes the energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it. It has wave-like properties so you could also call radiation “electromagnetic waves”.

An increase in the movements of particles in a substance is associated with an increase in energy

Answers

Answer: More atoms and higher temperature mean more thermal energy.

Explanation: The greater the motion of particles, the higher a substance's temperature and thermal energy. A substance's total thermal energy depends on its temperature, number of atoms, and physical state.

The greater the motion of the particles, the more thermal heat there is (increase in temperature).

A student creates a mixture of water and washing soda weighing 10 g and a mixture of water and epsom salts weighing 15 grams. He knows that when he mixes the two substances a chemical change will occur. According to the law of conservation of mass, what should the weight of the products be after he mixes them?

Answers

Answer: 25g

Explanation:

Although mass can be rearranged or change in form, it cannot be created or destroyed during a chemical reaction. In short, the total mass of the starting materials (reactants) will equal the mass of the product. This statement summarizes the Law of Conservation of Mass

Answer: 25g

Its summers are cold and short. Its winters are dark and frigid. In which climate zone is Plateau Station likely located?

Answers

polar, because it is cold with cold short summers with dark frigid winters

Polar, because it is 1) described as one of the coldest places on Earth. 2) it has cold and short summer and has dark and frigid winters.

In one to two sentences, explain how the loss of Arctic sea ice may affect the ocean currents and climate near the Western European coast

Answers

Changes to the Beaufort Gyre, a major Arctic Ocean current, could have widespread impacts. A new NASA study says that human-caused climate change is rapidly melting Arctic ice and disrupting ocean currents — which could make Western Europe cooler.

The cold tide may cause the Atlantic currents that bring warmth to Western Europe to slow down. According to NASA's news release, disruptions to the Gulf Stream would have a negative impact on ocean life and the communities that rely on it.

What happens if Arctic ice melts?

If all the ice on Antarctica, Greenland, and in mountain glaciers around the world melted, sea level would rise by approximately 70 meters. The ocean would engulf all coastal cities. And the land area would be significantly reduced.

The loss of older ice indicates that the Arctic ice cover is thinning. Evidence also suggests that the melt season has lengthened; ice is melting earlier in the year and freezing later than it used to.

Thus,The cold tide could slow the Atlantic currents that bring warmth to Western Europe. Disruptions to the Gulf Stream, according to NASA, would have a negative impact on ocean life and the communities that rely on it.

Answer:

Explanation:

betuase im write

Answer:

If I were to be a scientist, I'd be a botanist. A botanist is a scientist who studies plants. For example, they study many different aspects like their genetic, physical structure, and the distribution. They also study the relationship between plants and their different environments.

I would choose to be a botanist, because they help save our plants which are very important. They also help with telling others what exactly causes pollution and possible ways to stop it. Botanist also help with providing human resources like food. Without botanist, we would have a lot less of resources that we use in everyday life.

I can see my life as a botanist in many different ways. I might be put in the chemical based section or I might be put in the analysis of plants. Overall if I were to see myself as any kind of scientist, It would have to be a botanist.

Answers

Respiration: body obtains and uses oxygen and removes carbon dioxide & water.

Two parts to respiration:

1. Breathing:

a. Inhalation: contraction – muscle moves down / lungs expand

b. Exhalation: air moves out automatically

2. Cellular respiration: chemical reaction that uses oxygen to release energy from food

What is respiration?

Respiration is the process by which organisms take the oxygen from the external environment and expel the carbon dioxide in the opposite direction, which produces energy and other side output such as water.

Actually, there are three types of respiration:

1. Breathing or external respiration: a mechanical process to take the oxygen into our body and expel the carbon dioxide to the environment. This process includes:

a. Inhalation: diaphragm muscle contracts (moves down), lungs expand and air move in

b. Exhalation: diaphragm muscle relaxes and air move out

2. Internal respiration: an exchange process between gases in the blood and body cells.

3. Cellular respiration: a metabolic/chemical process that extracts energy from food by using oxygen. It produces carbon dioxide and water as well.
