Because of the build up of pressure. There is so much steam coming from such a compressed point, it’s coming out in force.
Now think of that same spot being closed, it only has one place to go but it can’t leave, so that pressure will build and build and then BOOM, it explodes.
In short, the answer is the pressure being released from a small point, and how that energy is released.
Hi! the atom in this particular problem has emitted an alpha particle in a nuclear reaction.
Glad I could help, and happy learning!
Rubbing water (isopropyl alcohol) has lesser surface tension than that water.
Water possesses a surface tension of 72 dynes/cm.
Whereas rubbing alcohol has a surface tension of 23 dynes/cm.
<h3>what is surface tension?</h3>
Surface tension is the propensity of liquid surfaces at rest to shrink to the smallest possible surface area.
Because the atoms on the outside of the molecules (often hydrogens) lack strong hydrogen bonding capabilities, most organic liquids have very low surface tensions. Because isopropanol contains just 28%, OH and the remainder is CH or CH3, the linkages that hold a droplet together are few and far between.
The only substance with a higher surface tension than water is liquid mercury (450 dyne/cm).

Answer:
143 batteries does Benny need to sample
Explanation:
Given data
confidence level = 97%
error = ±10 hours
standard deviation SD = 55 hours
to find out
how many batteries does Benny need to sample
solution
confidence level is 97%
so a will be 1 - 0.97 = 0.03
the value of Z will be for a 0.03 is 2.17 from standard table
so now we calculate no of sample i.e
no of sample = (Z× SD/ error)²
no of sample = (2.16 × 55 / 10)²
no of sample = 142.44
so 143 batteries does Benny need to sample
