The lake went from a liquid to a solid
Explanation:
Since it was so cold overnight, the temperature of the lake increased to the fact that it turned hard enough to skate on. or The temperature outside was so cold it froze the lake solid
Explanation:
The given data is as follows.
= 4.60 L, = 365 mm Hg
= 2.60 L, = ?
= (20 + 273) K = 293 K, = (36 + 273) K = 309 K
Since, number of moles of gas are equal so, according to ideal gas equation:
=
=
= 681.03 mm Hg
Thus, we can conclude that new pressure is 681.03 mm Hg.
