As temperature increases, molecules move faster.

Substances that dissolve well in water are often described a hydrophilic.

An exothermic reaction releases heat to the surroundings.

 Gas solubility tends to increase with increasing temperature.

Extended Answer Question: Answer the following in approximately one paragraph (~3-5 sentences) that fully explains your thinking.  Your notes and the textbook may be accessed during the answering of this question but our class discussions may not.  Responses will be graded on the accuracy of chemistry terminology used and the completeness of the explanation, including how well ideas are connected and supported.  Grammar or spelling will not influence grading. QUESTION: Table sugar and table salt are both white crystalline solids. How do they differ in composition, properties, and bonding?

QUESTION During our discussions we watched a video in which a balloon is brought near a stream of flowing water.  As noted in the image below, the stream of water bends toward the balloon as it is brought near.  Explain what is happening and why this occurs.  You may recall a video of this from one of our class discussions. 

Now listen to the five brief recordings provided here. Under Section 4 on the paper exam, indicate which of the five recordings exhibit the above perceptual characteristics. Some clips may exhibit multiple characteristics; some characteristics may be present in multiple videos! (4 points per characteristic) Note: the checkbox below is just so you can indicate to Canvas that you are done with this question.  Recording A:    Recording B:    Recording C:    Recording D:    Recording E:  

Section 7: Case Study 2 The next 4 questions refer to the following information (case also provided under Section 7 in paper exam).  — A 66-year-old man was referred for a speech evaluation by a neurologist to “see if there were any hints in his speech as to the type of problem he has”. When the patient comes to your office, you note that he has somewhat decreased facial expression, and doesn’t blink very often. During your intake conversation, you note that he has:  Equivocally slow speech rate Slightly quiet, hoarse voice  Occasional repeated phonemes at the beginning of words Slightly decreased intelligibility, especially near the ends of sentences.  You then conduct an oral mechanism exam. You note:  Symmetrical face with defined nasolabial folds Mild tremulousness of tongue, lips, and jaw during sustained postures Good strength when resisting tongue and cheek pressure Slightly decreased palatal elevation during repeated “ah”  Reflexes within normal range You then ask the patient to complete the DDK tasks. You note:  Accelerated rate during AMRs Normal to equivocally slow rate during SMRs Decreased articulatory distinction between consonant and vowel intervals  You then ask the patient to say ah as long as they possibly can. You observe:  12 seconds sustained voicing, but quiet  Mild vocal flutter You asked the patient to take a deep breath and try to produce ah as loud as they can. He produces a noticeably louder ah, but still can’t sustain it for very long. 

BONUS (up to 3 points) What speech diagnosis would you give clip A? Briefly justify your answer. 

BONUS (up to 5 points)  SIT (Speech Intelligibility Treatment–“big mouth, strong voice”) and SPEAK OUT!/LOUD Crowd are both therapies that result in increased loudness. Discuss:  The principal speech disorder each treatment is targeted at (1 point);  The neural mechanism driving each disorder (1 point);  How each therapy uses different instructions to address the mechanism driving the speech disorder and increase intelligibility (3 points)
