Answer:
Explanation:
Let assume that heating and boiling process occurs under an athmospheric pressure of 101.325 kPa. The heat needed to boil water is:
![Q_{water} = (1.4\,L)\cdot(\frac{1\,m^{3}}{1000\,L} )\cdot (1000\,\frac{kg}{m^{3}} )\cdot [(4.187\,\frac{kJ}{kg\cdot ^{\textdegree}C} )\cdot (100^{\textdegree}C-25^{\textdegree}C)+2257\,\frac{kJ}{kg}]](https://tex.z-dn.net/?f=Q_%7Bwater%7D%20%3D%20%281.4%5C%2CL%29%5Ccdot%28%5Cfrac%7B1%5C%2Cm%5E%7B3%7D%7D%7B1000%5C%2CL%7D%20%29%5Ccdot%20%281000%5C%2C%5Cfrac%7Bkg%7D%7Bm%5E%7B3%7D%7D%20%29%5Ccdot%20%5B%284.187%5C%2C%5Cfrac%7BkJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%20%29%5Ccdot%20%28100%5E%7B%5Ctextdegree%7DC-25%5E%7B%5Ctextdegree%7DC%29%2B2257%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D%5D)
The heat liberated by the LP gas is:
A kilogram of LP gas has a minimum combustion power of 
. Then, the required mass is:
Answer:Discrete system are those system which change the state at the discrete point of time and continuous system are those which have state change at continuous period of time.
Explanation:
- The major difference between discrete and continuous system is that, discrete system has state change over a discontinuous time period whereas the change of state in continuous system is over a continuous time period .
- Variations can be found in the discrete system signal but in continuous system variation cannot be found input and output signal.
- Example:-
Discrete system:-employees reporting at office at different time like
9:10am, 9:15am etc
<u> Continuous system</u>:-the water flow over a dam in particular quantity

Question:
John read the first 114 pages of a novel, which was 3 pages less than ⅓ of the novel. Write an equation to determine the total number of pages (P)
Answer:
114 = ⅓P - 3
Explanation:
Given
Number of pages read = 114
Total pages in novel = p
The relationship between the pages read by John and the total pages is analysed as follows:
3 less than ⅓ of total pages means:
⅓ of total pages - 3
Recall that P represents the total pages in the novel
So, the expression becomes
⅓ * P - 3
⅓P - 3
This means that the pages read by John is ⅓P - 3
This implies that the equation to determine the number of pages in the novel is
⅓P - 3 = 114
Solving further to get the actual number of pages;
Multiply both sides by 3
3(⅓P - 3) = 114 * 3
3 * ⅓P - 3 * 3 = 114 * 3
P - 9 = 342
Add 9 to both sides
P - 9 + 9 = 342 + 9
P = 351
Hence the number of pages is 351
