Substance X has a specific heat capacity that is twice as large as Substance Y. If both samples ended up at the same change in t
1 answer:
Answer:
Substance X has a smaller mass
Explanation:
The relationship between the mass of the two samples is that the mass of X is smaller compared to the mass of Y.
The specific heat capacity is given as:
C =
We can see that the higher the specific heat capacity the lesser the mass or simply put, the specific heat capacity of a body is inversely related to its mass.
If the amount of heat is constant i.e the same and the specific heat capacity of X is twice that of Y, then substance X has a smaller mass

Explanation:
From the information given:
Feed F = 150.0 kmol/hr
The saturated liquid mixture of the distillation column is = 30%
Reflux ration = 2.0%
methanol distillate mole fraction = 0.990
recovery of methanol in the distillate = 97.0%
The distillate flow rate D can be determined by using the formula;
D = 0.97 × 150 × 0.3
D = 43.65 kmol/h
The bottom flow rate Balance B on the column is:
F = D + B
150 = 43.65 + B
B = ( 150 - 43.65 )kmol/h
B = 106.35 kmol/h
The methanol mole fraction in the bottom can be computed by using the formula:
150(0.3) = 43.65(0.999) + 106.3()
45 = 43.60635 + 106.3()
45 - 43.60635 = 106.3()
1.39365 = 106.3()
= 1.39365 / 106.3
= 0.013
the fractional recovery of water in the bottoms f is calculated as:
f = 0.99969
