Phases of Matter Activity
Now it is your turn to show what you know about phases of matter and thermal energy transfer! Your task is to create a presentation to explain the transformation of a substance as it changes phases. You may choose to write a story or create a comic strip. For your story or comic, you will create a main character and detail the adventure as your character is exposed to thermal energy, causing it to undergo phase changes from a solid, to a liquid, to a gas. You may create your own comic strip using drawings, presentation software, or this comic strip template.

Your presentation must include the following:

title and introduction of your character, including what substance the character is made of
source of thermal energy your character encountered (conduction, convection, and/or radiation)
detailed description and/or diagram of the particle transformation from solid to liquid phase
detailed description and/or diagram of the particle transformation from liquid to gas phase
You may get creative on this activity. If you are unsure if your idea or software for a presentation will work, contact your instructor for assistance. Be sure to review the grading rubric before you begin.

lol i know this isnt the best but Your comic strip can be about how when you put smores in a campfire, the smores become burnt  that is example of energy transfer because energy is traveling as heat to another object.

The blue colour of the sky results from the scattering of sunlight by air molecules. Blue light has a frequency if about 7.5*10^14Hz

Calculate the energy of a mole of photon associated with this frequency

Answers

Answer: The energy of a mole of photon associated with this frequency is [tex]49.5\times 10^{-20}J[/tex]

Explanation:

The energy and frequency are related by :

[tex]E=N\times h\times \nu[/tex]

E = energy of photon

N = number of moles = 1

h = planks constant = [tex]6.6\times 10^{-34}Js[/tex]

[tex]\nu[/tex] = frequency = [tex]7.5\times 10^{14}Hz[/tex]

[tex]E=1\times 6.6\times 10^{-34}Js\times 7.5\times 10^{14}s^{-1}=49.5\times 10^{-20}J[/tex]

The energy of a mole of photon associated with this frequency is [tex]49.5\times 10^{-20}J[/tex]

Who isJefferson referring to when he says,their, them, and they?" The Clemson Company reported the following results last year for the manufacture and sale of one of its products known as a Tam. Sales (6,500 Tams at $130 each) $845,000 Variable cost of sales 390,000 Variable distribution costs 65,000 Fixed advertising expense 275,000 Salary of product line manager 25,000 Fixed manufacturing overhead 145,000 Net loss ($55,000) Clemson Company is trying to determine whether or not to discontinue the manufacture and sale of Tams. The operating results reported above for last year are expected to continue in the foreseeable future if the product is not dropped. The fixed manufacturing overhead represents the costs of production facilities and equipment that the Tam product shares with other products. Assume that discontinuing the Tam product would result in a $120,000 increase in the contribution margin of other product lines. Required:How many Tams would have to be sold next year for the company to be as well off as if it just dropped the line and enjoyed the increase in contribution margin from other products?
