<h3><u>Answer;</u></h3>
= 3032.15 kPa
<h3><u>Explanation;</u></h3>
Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
Volume = 7.5 L, T = 274 +273 = 547 K, N = 5 moles
Therefore;
Pressure = nRT/V
= (5 × 0.08206 × 547)/7.5 L
= 29.925 atm
But; 1 atm = 101325 pascals
Hence; Pressure = 3032150.63 pascals
<u>= 3032.15 kPa</u>
Answer:
It's the oesophagus.
Explanation:
The worm digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. The oesophagus is not mentioned. Thus, it's not part of the worm digestive system.
Two helium nuclei fuse to form beryllium nuclei which is highly unstable and spontaneously decays rapidly.
The distance between molecules INCREASES when the substance vaporizes
Explanation:
The distance between the molecules increase due to the fact that as you put more energy into the substance the kinetic energy of the molecules increases. This means they are vibrating more vigorously and the collision between the molecules are becoming more energetic. This means the collisions fling the molecules far away from each other (due to their increased momentum) hence the increased average distance between molecules.
