A sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°C. If the system is at dynamic equilibrium, which of these statements is true?
This question is missing a few details. I've found the complete question online. It is as follows:
Answer each of the following questions according to the instructions given. Question 1 (a–b) is based on the following paragraph.
A trip to the ocean can be a relaxing escape from the everyday pressures of life. A sailboat glistening on the horizon provides a mental escape to faraway places. The rhythm of the ocean beating against the sand is sedating music to a troubled mind. A slow, gentle breeze can relax your tensions. You should always be careful to avoid overexposure to the sun at the beach.
1. a. Write the sentence that is the topic sentence of the paragraph. b. Write the sentence that is unrelated to the topic and can be eliminated.
Answer and explanation:
1.a. The topic sentence is the very first sentence "A trip to the ocean can be a relaxing escape from the everyday pressures of life."
A topic sentence has the purpose of expressing the main idea of the paragraph in which it is inserted. It works as a map of the paragraph, letting readers know where the author's going and how he is getting there in terms of the idea being developed. In this case, the paragraph is clearly talking about relaxation and how the ocean can help us relax.
1.b. The sentence that is unrelated to the topic and can be eliminated is the last one, "You should always be careful to avoid overexposure to the sun at the beach.
" Even if this piece of information is useful, it does not really connected to the topic of relaxation. This sentence does not help develop the topic sentence at all and, therefore, can be eliminated.
5 however an argument could be made for 3
