Explanation:
The given data is as follows.
Mass of refrigerant, m = 10 kg
Volume of the refrigerant, V = 1.595
Formula for specific volume of the refrigerant is as follows.
v =
= 0.1595
So, at specific volume will be within and and pressure is constant.
The fluid will be in super-heated state at temperature and at T = pressure 1 bar = 0.1 MPa.
According to super-heated tables, the specific volume is v = 0.30138 .
Hence, the final volume will be calculated as follows.
=
= 3.0138
Thus, we can conclude that final volume of the R-134a is 3.0138 .
I suppose that the question ask the following:
What is the mass of a sample, composed of C₃H₅N₃O₉ molecule, that contains 100 g carbon?
First we calculate the molecular mass of our molecule C₃H₅N₃O₉.
molecular mass = 12 × 3 + 1 × 5 + 14 × 3 + 16 × 9 = 227 g/mol
Now we devise the following reasoning:
if 227 g of our molecule contains 27 g of carbon
then X g of our molecule contains 100 g carbon
X = (100 × 227) / 27 = 840.7 g
Answer:
B
Explanation:
Asteroid - A rock that rvolves arounf the sun / star.
Moon - A natural satillite that revolves around earth/ planet.
Answer:
The chemical energy in food can be converted to another form of chemical energy when it is stored as glucose or fat. It can be converted to thermal energy because our body produces heat when digesting our food. The chemical energy in our food can also be converted to mechanical energy in the form of muscle movement.
