How does distance from the thermal energy source affect the amount of thermal energy transfer occurring in a substance

Chemistry

iren [92.7K]1 year ago
4 0

The distance from the thermal energy source affect the amount of thermal energy transfer occurring in a substance in a way that area that the radiation is spread over is four times as large for just the double distance.

Thermal energy that can transfer between substances always does so from one that is warmer to one that is cooler. Conduction, convention, and radiation are the three categories. Distance causes the heat radiation emitted by a source, such the sun, to disperse.

As it moves away from the source, the same quantity of energy is dispersed over a larger and larger sphere every second. For simply the twice distance, the radiation's distribution area is four times as large.

The solar constant (also known as the solar coefficient), abbreviated S, refers to the Sun's intensity on Earth, W/m^{2}, in units. This information reveals how much radiation enters a square metre of Earth (or any other planet at a similar distance from the sun).

HNO3 + S --&gt; H2SO4 + NO Now identify the element oxidized and the element reduced. Which element is oxidized? Which element i
OleMash [197]

<u>Answer:</u> S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction

<u>Explanation:</u>

The oxidation reaction is defined as the reaction in which a chemical species loses electrons in a chemical reaction. It occurs when oxidation number of a species increases.

A reduction reaction is defined as the reaction in which a chemical species gains electrons in a chemical reaction. It occurs when oxidation number of a species decreases.

For the given chemical reaction:

HNO_3+S\rightarrow H_2SO_4+NO

<u>On the reactant side:</u>

Oxidation number of H = +1

Oxidation number of N = +5

Oxidation number of O = -2

Oxidation number of S = 0

<u>On the product side:</u>

Oxidation number of H = +1

Oxidation number of N = +2

Oxidation number of O = -2

Oxidation number of S = +6

As the oxidation number of S is increasing from 0 to +6. Thus, it is getting oxidized. Similarly, the oxidation number of N is decreasing from +5 to +2. Thus, it is getting reduced.

The oxidation numbers of O and H remain the same on both sides of the reaction. Thus, they are neither getting oxidized or reduced.

Hence, S is getting oxidized, N is getting reduced and O and H undergo no oxidation or reduction

Which statements about oxygen and nitrogen are true? Select all the correct answers. a. They are both normally found as gases in
allsm [11]

a. They are both normally found as gases in the atmosphere.  TRUE

That is correct, the oxygen and nitrogen are found in large quantities in the air around us.

b. They can be either liquids or gases. TRUE

Under certain temperatures any gas will transform into a liquid.

c.They turn from gas to liquid at the same temperature. FALSE

Oxygen it will pass into a liquid at -183 °C while nitrogen pass into a liquid at -195.8 °C.

d.They can be changed from gases to liquids by heating them. FALSE

The gases change to liquids by cooling them.

Which of the following is a completely elastic collision? A. a ball rebounds against a wall, reversing its direction, but at onl
Dmitry_Shevchenko [17]

Answer:

Answer E.

For a collision to be completely elastic, there must be NO LOSS in kinetic energy.

We can go through each answer choice:

A. Since the ball rebounds at half the initial speed, there is a loss in kinetic energy. This is NOT an elastic collision.

B. A collision involving sticking is an example of a perfectly INELASTIC collision. This is NOT an elastic collision.

C. A reduced speed indicates that there is a loss of kinetic energy. This is NOT elastic.

D. The balls traveling at half the speed after the collision indicates a loss of kinetic energy, making this collision NOT elastic.

E. This collision indicates an exchange of velocities, characteristic of an elastic collision. We can prove this:

Let:

m = mass of each ball

v = velocity

We have the initial kinetic energy as:

KE = \frac{1}{2}mv^2 + 0 = \frac{1}{2}mv^2KE=21mv2+0=21mv2

And the final as:

KE = 0 + \frac{1}{2}mv^2 = \frac{1}{2}mv^2KE=0+21mv2=21mv2
