What is ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

How much heat energy required to convert following?

How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?

Specific Heat of Ice - 2.09 j/g * c

This is how I did it and the answer is wrong...Please check and correct me

Q = m * Cice * Change in Temp

Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj

Answers

                                         Answer and Explanation

According to Science J Rank,

__________________________________________________________

Heat Energy

Heat energy is the movement of energy from one object to another. It is also called thermal energy. It can move in three ways: through conduction, convection, or radiation.

__________________________________________________________

Conduction occurs when heat moves directly from one object to another. What happens when you leave your car parked in a sunny parking lot on a hot day? The heat of the sun passes directly through the metal of the car and heats the air (and seats) on the inside.

__________________________________________________________

Energy Hot vehicles in the summer are a form of heat energy.

Convection is the movement of hot liquids or gases. For example, when you boil water, the liquid nearest the flame heats up first. As it gets hot, it rises, and the cooler water goes to the bottom where it gets heated. This continues until the water is boiled.

__________________________________________________________

Radiant Energy

Radiant energy is the energy created through electromagnetic waves, such as light, heat, or radio waves. The sun is our major source of radiant energy because it gives off a great amount of heat and light. Scientists use the electromagnetic spectrum to discuss the types of radiant energy. The electromagnetic spectrum lists all the types of radiant energy by the length of their waves. The shorter the wave, the more energy and heat are created.

__________________________________________________________

Electrical Energy

A huge maze of wires in every house carries electrical energy to do many different jobs, from lighting your home to cooking food.

Electricity starts at the atomic level. Atoms are made up of a nucleus, protons, and electrons. We create electricity by forcing electrons to move from atom to atom. Electrical energy is the movement of electrons through a conductor. A conductor is a material that can carry electricity, like the wiring in homes.

__________________________________________________________

Generators create the electricity used in our everyday lives, but other forms of electric energy occur naturally.

Lightning occurs when electrons are discharged from a cloud. Lightning is so powerful that if we could capture the electricity in a single bolt, it could power our entire home for days.

__________________________________________________________

Static Electricity occurs when an object (or person) gets charged with electrons. You may have experienced this when scuffing your feet on a carpet and then touching a doorknob. The electrons you built up jump from your hand to the metal of the doorknob, causing a powerful shock!

__________________________________________________________

Chemical Energy

Chemicals contain stored, or potential, energy to hold their atoms together. When chemicals are mixed together, a reaction can occur. Chemical energy is the energy released through a chemical reaction.

We can use the heat that these reactions give off. We can use it to cook, to heat our homes, and to burn the gasoline that moves our cars.

One of the major uses of chemical energy is to help produce electrical energy. Coal, gas, and other fuels are burned to run electric generators.

The chemical energy in batteries is changed into the electrical energy we need to run everything from flashlights to toys.

__________________________________________________________

Nuclear Energy

Atoms are so small that until recently even the most powerful microscopes could not see them. Yet when we split the nucleus of an atom, a tremendous amount of energy is released. Nuclear energy is the potential energy stored in the nucleus of an atom.

In a nuclear power plant, a reactor is used to split uranium atoms. This heat is used to turn water to steam. The steam powers a generator that creates electricity.

Nuclear power plants create about 20 percent of the electricity in the United States. Coal, oil, and natural gas help produce the rest.

Sodium is a soft, white metal that reacts violently with water. Chlorine is a poisonous yellow-green gas. During the chemical reaction between sodium and chlorine, table salt is produced. Which of the following statements correctly compares and contrasts the reactants with the resulting products used in a chemical equation?

A. The reactants are dangerous and the product can be eaten
B. The reactants and the products observe the law of conservation of mass
C. The reactants are a solid and a gas and the product is a gas
D. The reactants and the products are the same color

Answers

Answer:

B. The reactants and the products observe the law of conservation of mass

Explanation:

The reaction equation is given as:

            2Na  +  Cl₂  →   2NaCl

Such a chemical reactions usually obeys the law of conservation of mass. The law states that "in a chemical reaction, matter is neither created nor destroyed but bonds are rearranged".

So, the most correct thing is that reactants and products observe the law of conservation of mass. The number of atoms on both sides of the expression will be the same. Therefore, option B is correct.

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?

- 20 mL
- 259 mL
- 25 mL
- 50 mL

Answers

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

What is specific heat? How are the factors affecting it?

Answers

Answer : “Amount of heat needed to raise the temperature of 1 kg of a material by 1 c or k.”

Equation used to solve: Q=mc^T

- Change in temp
- Mass of the system
- Subtance and phase of substance

Answer:

Specific heat, ratio of the quantity of heat required to raise the temperature of a body one degree to that required to raise the temperature of an equal mass of water one degree.

Explanation:

by dividing the heat capacity by the quantity of substance in a body, the resulting specific heat capacity is a function of the structure of the substance itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store thermal energy.
