In a series of experiment, block B is to be placed in a thermally insulated container with block A , which has the same mass as block B. In each experiment, block B is initially at a certain temperature T B , but temperature T A of block A is changed front experiment to experiment. Let T f represent the final temperature of the two blocks when they reach thermal equilibrium in any of the experiments. Figure 18-53 gives temperature T f versus the initial temperature T A for a range of possible values of T A , from T A 1 = 0 K to T A 2 = 500 K. The vertical axis scale is set by T fs = 400 K. What are (a) temperature T B and (b) the ratio c B / c A of the specific heats of the blocks? Figure 18-53 Problem 74.

In a series of experiment, block B is to be placed in a thermally insulated container with block A, which has the same mass as block B. In each experiment, block B is initially at a certain temperature TB, but temperature TA of block A is changed front experiment to experiment. Let Tf represent the final temperature of the two blocks when they reach thermal equilibrium in any of the experiments. Figure 18-53 gives temperature Tf versus the initial temperature TA for a range of possible values of TA, from TA1 = 0 K to TA2= 500 K. The vertical axis scale is set by Tfs = 400 K.

How can you tell which vowel is being produced here ( “ee,” “ah,” or “oo”)? Also, how would you be able to tell for the other vowels?
You want to fabricate a soft microfluidic chip like the one below. How would you go about
fabricating this chip knowing that you are targeting a channel with a square cross-sectional
profile of 200 μm by 200 μm. What materials and steps would you use and why? Disregard the
process to form the inlet and outlet.

1. What are the key steps involved in the fabrication of a semiconductor device.
2. You are hired by a chip manufacturing company, and you are asked to prepare a silicon wafer
with the pattern below. Describe the process you would use.
High Aspect
Ratio
Trenches
Undoped Si Wafer
P-doped Si
3. You would like to deposit material within a high aspect ratio trench. What approach would you
use and why?
4. A person is setting up a small clean room space to carry out an outreach activity to educate high
school students about patterning using photolithography. They obtained a positive photoresist, a
used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask
with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full
resist gets developed, and they are unable to transfer the pattern onto the resist. Help them
troubleshoot and find out why pattern of transfer has not been successful.
5. You are given a composite…
