Answer:
1.06 atm
Explanation:
We are given the following variables to work with:
Initial pressure (P1): unknown
Initial temperature (T1): 348 K
Final temperature (T2): 506 K
Final pressure (P2): 1.55 atm
We are asked to find the initial pressure (P1). We want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

We can rearrange the law algebraically to solve for
.

Substitute your known variables and solve:

Ionic compounds share electrons :)
Answer:
Wind moving over a water or land surface can also carry away water vapor, essentially drying the air, which leads to increased evaporation rates.
