1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:

Answers

Explanation:

The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

What is the difference between permanent gases and variable gases in the atmosphere?

Answers

Answer:

the difference is that permanent gases have larger residence times and Variable gases have shorter residence times

the difference between permanent gases and variable gases in the atmosphere is permanent gases are gases that have a very low dew point.

What are the characteristics of the atmosphere?

The Earth's atmosphere is basically composed of a mixture of gases, being 78% Nitrogen, 21% Oxygen and 1% Argon. In addition, traces of carbon dioxide, water vapor and other gases are found, but in very small amounts.

In this way,  permanent gases are gases that have a very low dew point.

What are the states of energy? List the Laws of Thermodynamics.

Answers

Answer:

The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.

Explanation:



What are the states of energy? List the Laws of Thermodynamics.
Answer: The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

Paragraph: Discuss the three laws of thermodynamics.
Key Points

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.
The second law of thermodynamics states that the entropy of any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Terms

absolute zeroThe lowest temperature that is theoretically possible.
entropyA thermodynamic property that is the measure of a system’s thermal energy per unit of temperature that is unavailable for doing useful work.

System or Surroundings

In order to avoid confusion, scientists discuss thermodynamic values in reference to a system and its surroundings. Everything that is not a part of the system constitutes its surroundings. The system and surroundings are separated by a boundary. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. Everything outside of the boundary is considered the surroundings, which would include the container itself.

The boundary must be clearly defined, so one can clearly say whether a given part of the world is in the system or in the surroundings. If matter is not able to pass across the boundary, then the system is said to be closed; otherwise, it is open. A closed system may still exchange energy with the surroundings unless the system is an isolated one, in which case neither matter nor energy can pass across the boundary.


A Thermodynamic SystemA diagram of a thermodynamic system
The First Law of Thermodynamics

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

A way of expressing the first law of thermodynamics is that any change in the internal energy (∆E) of a system is given by the sum of the heat (q) that flows across its boundaries and the work (w) done on the system by the surroundings:

Δ
E
=
q
+
w
Δ
E
=
q
+
w

This law says that there are two kinds of processes, heat and work, that can lead to a change in the internal energy of a system. Since both heat and work can be measured and quantified, this is the same as saying that any change in the energy of a system must result in a corresponding change in the energy of the surroundings outside the system. In other words, energy cannot be created or destroyed. If heat flows into a system or the surroundings do work on it, the internal energy increases and the sign of q and w are positive. Conversely, heat flow out of the system or work done by the system (on the surroundings) will be at the expense of the internal energy, and q and w will therefore be negative.

The Second Law of Thermodynamics

The second law of thermodynamics says that the entropy of any isolated system always increases. Isolated systems spontaneously evolve towards thermal equilibrium—the state of maximum entropy of the system. More simply put: the entropy of the universe (the ultimate isolated system) only increases and never decreases.

A simple way to think of the second law of thermodynamics is that a room, if not cleaned and tidied, will invariably become more messy and disorderly with time – regardless of how careful one is to keep it clean. When the room is cleaned, its entropy decreases, but the effort to clean it has resulted in an increase in entropy outside the room that exceeds the entropy lost.

The Third Law of Thermodynamics

The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has. Specifically, the entropy of a pure crystalline substance (perfect order) at absolute zero temperature is zero. This statement holds true if the perfect crystal has only one state with minimum energy.

"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."
