If 5 J (joules) of electrical energy is used to power an iron, how many joules of heat and steam should it be transformed into?

Answers

Answer:

maybe 25 joules

Explanation:

please mark me as a brainlist

If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.

What is energy?

Energy is referred to by scientists as the capacity for work. People have figured out how to transform energy from one form to another and then use it to accomplish tasks, making modern civilization possible.

Walking and bicycling, driving cars on roads and boats through water, cooking meals on stoves, making ice in freezers, lighting our homes and workplaces, producing goods, and sending astronauts into space all require the usage of energy.

Energy is capable of changing its forms. For instance, a person's body stores chemical energy from the food they consume until they may use it as kinetic energy when working or playing.

Therefore, If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.

item 3 steel is an alloy containing fe atoms and c atoms. which of the following diagrams best represents the particle-level structure of steel?

Answers

An alloy is obtained when an element is combined with another physically and not chemically. The image that accurately represents steel is the image in which carbon atoms are sandwiched between iron atoms.

Steel is an alloy of iron and carbon. In an alloy, the atoms one element is sandwiched in between atoms of another element in its crystal. Usually, allows are formed to improve certain desired properties of substances. The percentage of carbon included in steel depends on its intended use.

Claim: An ecosystem can survive with only producers.


Do you agree or disagree with this claim? Explain your answer. Be sure to include evidence and reasoning.

Answers

Answer:

No.

Explanation:

The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

If 84.5 mol of an ideal gas occupies 21.5 L at 305 K, what is the pressure of the gas? pressure: atm​

Answers

Answer:

98.367 atm

Explanation:

For this, you must use the equation PV=nRT. Since you are looking for P, rearrange the equation so that P= nRT/V.

Now collect the information you have:

n (mol) = 84.5

R (ideal gas constant to find atm not every case) = .08206

T (temperature) = 305 K (always convert to kelvin)

V (volume in liters) = 21.5

Now Use P= (85.5 mol)×(.08206)×(305 K)/(21.5) to get your answer in atm

What is chemical reaction?

Chemical reaction is defined as a procedure in which one or more substances, known as reactants, are converted into one or more different substances, known as products.

It can also be defined as a method of chemically transforming one set of chemical substances into another.

There are basically six types of chemical reaction.

Combustion reactionDecomposition reactionNeutralization reactionRedox reactionPrecipitation reactionSynthesis reaction

Cellular respiration is defined as the process of oxidizing biological fuels in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which drives the bulk production of ATP.

It can also be defined as the process by which sugar from food is converted into energy within cells.

Thus, the  food molecules during cellular respiration they undergo chemical reactions with oxygen, releasing stored energy.

Write a 125 word summary of what you have learned in "Introducing the Microscope". Be sure to include steps on how to focus, how to solve for magnification, and what a field of view is and how to measure it.

Answers

Answer:

Introduction to Basic Microscopy. Microscopes are specialized optical instruments designed to produce magnified visual or photographic (including digital) images of objects or specimens that are too small to be seen with the naked eye.

Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.

Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.

There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.

In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.

In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.
