Find a counterexample, if possible, to these universally quantified statements, where the domain
for all variables consists of all integers.
a) ∀x (x2 ≥x)
b)∀x(x>0∨x<0) c) ∀x (x = 1)
A die is loaded in such a way that the probabilities of getting 1, 2, 3, 4, 5, and 6 are 1/2, 1/6, 1/12, 1/12, 1/12, and 1/12 respectively
Phase Diagram for Methane
1. What are the approximate temperature and pressure at the critical
point?
2. What are the approximate temperature and pressure at the triple
point?
3. Is methane a solid, liquid, or gas at 1 atm and 0 ºC?
4. What phase(s) will exist at point 1?
5. If solid methane at 1 atm is heated while the pressure is held
constant, will it melt or sublime?
gas has temp of 47C and pressure of 2.10⁵ pascal. What pressure would gas have after isochoric boiling it to 77C
Based from the phase diagram of water and carbon dioxide, answer the following
questions and justify your answers:
1. You have ice at 263 K (-10.0 °C) and 1.0 atm. What could you do to make
the ice sublime?
2. A sample of dry ice (solid CO2) is cooled to 173 K (-100.0 °C), and is set
on a table at room temperature (298 K; 25 °C). At what temperature is the
rate of sublimation and deposition the same (assume that pressure is held
constant at 1 atm)?
Illustrate the phase diagram of a substance given with the following points: a
triple point at 0.70 atm and 80 ºC; a normal freezing point at 100 ºC; a normal
boiling point at 350 ºC; and a critical point at 1.6 atm and 810 ºC. For this,
complete the following:
1. Roughly sketch the phase diagram, using units of atmosphere and degree
Celsius. Label the area 1, 2, and 3, and points T and C on the diagram.
2. Describe what one would see at pressures and temperatures above 1.25 atm
and 300 ºC.
3. Describe the phase changes from 100 ºC to 200 ºC at 1.5 atm.
4. What exists in a system that is at 1 atm and 100 ºC?
5. What exists in a system that is at 1 atm and 325 ºC?

Record the following transactions using the accounting equation and T accounts.
1. Owner contributed $50,000 in cash for company stock.
2. Purchased building for $120,000, making a $20,000 down payment and signing a promissory note for the balance.
3. Sold products to customers for $15,000 cash.
4. Paid utilities expense of $2,000.
5. Reduced note payable with an $8,000 cash payment (ignore interest costs).
6. Incurred expense of $3,000, to be paid in the future (accounts payable).
Collected $4,000 on an outstanding account receivable
Create a new project, and copy your code from Task 1 to the new project (copy the contents of the Main() method and the displayDetails() method) Adapt your Main() method to capture and display the details for 4 different people. The displayDetails() method should remain unchanged.
Create a user defined method named calcCost() that accepts two double values as input (length and width), and then computes the estimated cost of painting a room (walls only, not ceiling), assuming the room is rectangular and has four full walls and the walls are 2.6 meter high. The rate for the painting job is R20 per square meter. Your method should return the estimated cost to the calling method. Create a program whose Main() method prompts a user for the length and the width of a room in meter, then calls calcCost to calculate the estimated cost. Once calculated, you should display the estimated cost.
