Physics PS
Copy each problem and write your solutions to whole sheet/s of pad paper. Follow the format in problem solving. (Due Feb 26, 2012, Monday)


1. Calorimetry/Heat If the price of electrical energy is P 11.00 per kilowatt-hour, what is the cost of using electrical energy to heat the water in swimming pool (12.0m x 9.00 m x 1.5 m) from 15 to 27 deg. C?
2. Phase Change. An aluminum can with a mass of 0.500 kg contains 0.130 kg of water at a temperature of 80.0 deg. C. A 0.150 kg of ice at -2.0 is dropped into the can. Find the final temperature of the mixture. Assume no heat loss to the surroundings. The specific heat capacities of aluminum, water, and ice are 9.00 x 10^2 J/kg.Cdeg. , 4186 J/kg.Cdeg. , and 2.00 x 10^3 J/kg.Cdeg. respectively. The latent heat of fusion of ice is 33.5 x 10^5 J/kg.
Hint: Q(water) + Q(aluminum) = Q(ice)
3. Thermal Expansion. A brass cylinder is initially 20.0 deg.C. At what temperature will its volume be 0.300% larger than it is at 20.0 deg.C. The coefficient of linear expansion of brass is Alpha(brass) - 2.0 x 10^5 /Cdeg. Note:Beta = 3Alpha
4. Conduction. One end of an insulated (to the environment) metal rod is maintained at 100 deg.C, and the other end is placed in an ice-water mixture. The bar has a length of 50.0 cm and a cross-section area of 0.800cm^2. the heat conducted by the rod melts 3.00 g of ice in 5.00 min. The latent heat of fusion of ice is 80cal/g. Calculate the thermal conductivity k  of the metal.
5. Radiation. The supergiant star Betelgeuse has a surface temperature of about 2900 K and emits a radiant power of approximately 4.00 x 10^30 W. Assuming that Betelgeuse is a perfect emitter (e=1) and spherical, find its radius.

Internet Is Finally Back (02 Febuary 2013)
Thursday, February 2, 2012 by alrlchoa in

Yay! My Internet is back!
Back to business, here are the reminders for tomorrow:

Soc. Sci.:

- Marianne, Pama, Lyon, Adrian, and JP (correct me if I'm wrong) are going to be teaching about the ideas that propagated during the last/end of the Industrial Revolution.

Chem.:

-Homework is to be done in a 1/2 sheet of crosswise intermediate pad:

14.15 of Ma'am textbook(Chemistry: The Central Science 11th Edition):

Consider the following hypothetical reaction:

A(aq) --> B(aq)

A flask is charged with 0.065 mol of A in a total volume of 100.0 mL. The following data are collected.


Time in minutes
0
10
20
30
40


Moles of A
0.065
0.051
0.042
0.036
0.031


a) Calculate the number of moles of B at each time of the table, assuming that there are no molecules of B at time zero.
b) Calculate the average rate of disappearance of A for each 10-min interval, in the units of M/s.
c) Between t=10 and t=30, what is the average rate of disappearanceof B in units of M/s? Assume that the volume of the solution is constant.

Phy.:

- LT2 is now moved to the 15th of February
- Answer these questions in your notebook. These questions may also be used for consultation purposes:

Taken from the Giancolli,3rd Edition:

Page 270:

Number 5:
(I) The arm of a record player exerts a force of (1 g) x g on a record. If the diameter of the stylus is 0.0013 cm ( =0.5 mil = 0.5 x 10-3 in.) , calculate the pressure on the record groove in N/m2 and in the atmospheres.

Number 7:
(I) What is the difference in the blood pressure between the top of the head and the bottom of the feet of a 1.70-m-tall person standing vertically?

Number 10:
(II) The gauge pressure in each of the four tires of an 1800-kg automobile is 200 kPa. How much area of each tire is in contact with the ground?

Eng.:

- Long Test tomorrow about the stories. I you lost your stories, you may download them from the links here:

First Part(aka."a")\
Second Part(aka."s")
Third Part(aka."d")
Fourth Part(aka."f")
Fifth Part(aka."g")

- Don't forget to submit a bookmark with a Haiku on it by 1630 hours tomorrow to Sir Allan.

Bio.:

- Don't forget to read up on the different pheromones.

Math:

- Should be finished by tomorrow, unless you want to think about this during promenade:

HW7:

- Demonstrate on how to make a geometric pattern when given two tangent circles of unknown areas. Also, you may want to draw something inside the circles para wala lang.

Misc.:

- On the 6th of February, we will be having our outreach. Please have you reply slips signed by then because they most likelyq are also your Parent Consent Forms

- We will not be posting tomorrow, but will be after the promenade. It is so that everyone may have Saturday as a rest day.

- Mabuhay Ang Cesium 2013!!!

Please comment if I missed/wronged anything.
