Answer:
( a ) The specific volume by ideal gas equation = 0.02632
% Error = 20.75 %
(b) The value of specific volume From the generalized compressibility chart = 0.0142
% Error = - 34.85 %
Explanation:
Pressure = 1 M pa
Temperature = 50 °c = 323 K
Gas constant ( R ) for refrigerant = 81.49
(a). From ideal gas equation P V = m R T ---------- (1)
⇒ =
⇒ Here = Specific volume = v
⇒ v =
Put all the values in the above formula we get
⇒ v = ×81.49
⇒ v = 0.02632
This is the specific volume by ideal gas equation.
Actual value = 0.021796
Error = 0.02632 - 0.021796 = 0.004524
% Error = × 100
% Error = 20.75 %
(b). From the generalized compressibility chart the value of specific volume
= v = 0.0142
The actual value = 0.021796
Error = 0.0142 - 0.021796 =
% Error = × 100
% Error = - 34.85 %
The answer is photosynthesis. The plant converts CO2, Sunlight, and H2O (water) into sugars which acts as their "food" and oxygen which we use to breathe.
Answer : What is the effect of time and temperature on dissolution of different size of antacid tablets?
Explanation : According to the experiment performed as given in the question; first part deals with the temperature and time of reaction study of the antacid tablet.
In the second part, the size is altered and it reaction time is studied.
In complete experiment three factors are majorly focused i.e. time, temperature and size.
Based on this, one can frame many scientific questions, one example is given below;
Question : What is the effect of time and temperature on dissolution of different size of antacid tablets?
Answer:
The velocity of the 4.00 kg object after the collision is 12 m/s.
Explanation:
Given that,
Mass of object
Velocity of object
Mass of another object
Velocity of another object
We need to calculate the relative velocity
The relative velocity is 8 m/s in west before collision.
We know that,
In one dimensional elastic collision, the relative velocity before collision equals after collision but with opposite sign.
So, The relative velocity after collision must be 8 m/s in east.
So, The object of 6.00 kg is going 20 m/s and the object of 4.00 kg is slows down to 12 m/s.
Hence, The velocity of the 4.00 kg object after the collision is 12 m/s.
