Around 2,400 seconds would be in a 40.0 minute class
<em>Kinetic molecular Theory points:</em>
1. Gases molecules are always in random motion.
2. Gases molecule collide with each other and with the walls of container.
3. Gases molecules total volume is negligible as compare to container.
4. There is no attractive forces between the gases particles
5. K.E is directly proportional to absolute temperature.
<em>Why liquid are denser than gases according to K.M.T:</em>
1. As gases are in random motion, so they have weak forces/ no attractive forces (Acc. to KMT) due to this they are apart as compare to liquid which have stronger forces are closer to each other. So volume of gases will be greater. d= m/v
2. K. E of gases are greater than liquid due to this gases move randomly, apart from each another. Due to this their volume will be greater. d= m/v
3. Gases molecules total volume is negligible as compare to container which show that gases molecules have large spaces between them which causes lower in density.
Answer: tell that person how u feel
Explanation: If it doesn’t go well ask if u can just stay friends
Answer:
Here's what I find
Explanation:
You don't use ΔHfus. You use ΔHvap
There are some preliminary calculations:
- Use the density of the liquid to calculate its mass.
- Use the molar mass to calculate the moles (n)
The formula for the heat (q) absorbed during vaporization is
q = nΔHvap
Insert your numbers into the formula, do the calculation, and you have the answer.
