A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other. The truck parked overnight in a place where energy transferred out of the substance . In the morning . the substance was a gas. How were the molecules moving in the morning ?

Answer:

In the morning the molecules were moving away from each other with a smaller speed than when the truck was carrying the substance.

2. The reason is that the molecules contain less average kinetic energy, thus their average speed is lower.

Explanation:

Our model of the state (phases) of the substances describes the molecules of solids as not moving away from each other, they are relatively fixed with respect to each other, just vibrating; the molecules of liquids as free to slide pass each other, which permits they to flow, but not moving away from each other; and the the molecules of the gases as moving away from each other, which is the cause of them occupying the whole space of the container that holds them.

According to that, the substance that the truck was carryng was a gas, because the molecules were moving away from each other.

After parking overnight, where energy transferred out of the substance, in the morning, the substance was a gas. Hence, the molecules were moving away from each other too. This answer the first question.

Since energy was transferred out of the substance, in the morning the temperature of the substance decreased (but no enough to make it a liquid). The average kinetic energy of the gases depends only on the temperature. So, the average kinetic energy of the molecules in the morning was smaller than when the truck was carrying the substance. Since the kinetic energy is proportional to the square of the speed of the molecules, the smaller average kinetic energy means that the average speed of the molecules was smaller too. Hence, in the morning the molecules were moving away from each other with a lower speed than when the truck was carrying the substance.

Sarah stood staring at the whiteboard for an eternity. The class was over, and everyone had left for home. But, Sarah had lost the concept of time. She kept going back to the moment when she had overheard Betsy, her best friend, tell Raj that she had a crush on him.
"Betsy! Oh, Betsy! Did you forget how I felt about him?" Sarah gave words to her thoughts and buried her head in her hands. She was a wilted flower losing all hopes of spring. She hated the fact that it was a beautiful day. Buds were continuing their blooming, and birds were happily chirping on the tree outside the classroom. "Not fair!" she uttered the choked up words and felt like hiding from the world forever. That was when she felt a gentle tap on her back.
"There you are! I kept looking for you everywhere, girl," Betsy said. "Why do you look like a broken piece of a violin?"
"I heard what you said to him," Sarah responded without facing Betsy. She felt bees stinging at her eyes and volcanoes erupting from her heart. Sarah had never felt betrayal so strongly.
"Then you should be dancing," Betsy said, confused. "Raj was asking me if you had asked anyone out to prom yet because he has like the biggest crush in the universe on you! And, I told him you were waiting for him to ask. Was I not supposed to say that?"

Passage: "The Ambitious Guest" by Nathaniel Hawthorne

Nathaniel Hawthorne lived and wrote in the puritanical culture of 19th century New England. In the decade after he completed college, he spent most of his time in solitude writing his early short stories and a novel. When he was unable to support himself by writing, he tried several careers, but continued to write novels and short stories. Although he visited England and Italy, his best-known stories describe the gloom and loneliness of life in New England. He died in 1864.

One September night a family had gathered round their hearth, and piled it high with the driftwood of mountain streams, the dry cones of the pine, and the splintered ruins of great trees that had come crashing down the precipice. Up the chimney roared the fire, and brightened the room with its broad blaze. The faces of the father and mother had a sober gladness; the children laughed; the eldest daughter was the image of Happiness at seventeen; and the aged grandmother, who sat knitting in the warmest place, was the image of Happiness grown old. They had found the "herb, heart's-ease," in the bleakest spot of all New England. This family was situated in the Notch of the White Hills, where the wind was sharp throughout the year, and pitilessly cold in the winter, —giving their cottage all its fresh inclemency before it descended on the valley of the Saco. They dwelt in a cold spot and a dangerous one; for a mountain towered above their heads, so steep, that the stones would often rumble down its sides and startle them at midnight.

The daughter had just uttered some simple jest that filled them all with mirth, when the wind came through the Notch and seemed to pause before their cottage—rattling the door, with a sound of wailing and lamentation, before it passed into the valley.

The family were glad again when they perceived that the latch was lifted by some traveller, whose footsteps had been unheard amid the dreary blast which heralded his approach, and wailed as he was entering, and went moaning away from the door.

The door was opened by a young man. His face at first wore the melancholy expression, almost despondency, of one who travels a wild and bleak road, at nightfall and alone, but soon brightened up when he saw the kindly warmth of his reception. He felt his heart spring forward to meet them all, from the old woman, who wiped a chair with her apron, to the little child that held out its arms to him. One glance and smile laced the stranger on a footing of innocent familiarity with the eldest daughter.

"Ah, this fire is the right thing!" cried he; "especially when there is such a pleasant circle round it. I am quite benumbed; for the Notch is just like the pipe of a great pair of bellows; it has blown a terrible blast in my face all the way from Bartlett."
