this may seem like a dumb question

but if you have hot food in a plastic bag
why does the inside of the bag become wet

is it water condensation off the food or does the plastic sweat
from the heat

I have heard the big bang described as a sudden explosion of dense matter the approximate size of a marble. My question is, where did the marble come from? What was before that?

We use salt with ice and use this mixture outside a metal pot to prepre icecream in it. Also salt is used for melting ice on the streets on snowy days . How are both things explained by assuming the fact that the melting pt of ice is lowered by mixing salt ?
In the first case ok but what about the second?

I know that the capacitance is depended on area and distance etc etc. However, can someone explain to me the statement that as the area increases the, Elctrical field decreases.
C would increase because of the area, and V would decrease because of the E, so for this scenario would the charge be constant or increasing.

Can someone show in equation forms, please show how E would decrease.

My colleague keeps emailing round logic puzzles, and I normally spend several hours beating my head against the wall trying to figure out how many pirates it will take to extinguish 99 lightbulbs in the given time, using only one match and a banana (or something like that).

I wish to take revenge by setting him a really tough logic puzzle. Anyone know any good ones?

Too days later they were reported to of been seen in China.
