Answer:
T₁ = 194 K
Solution:
Data Given:
Initial Temperature = T₁ = <u>??</u>
Final Temperature = T₂ = 465 K
Initial Pressure = P₁ = 18.7 psi
Final Pressure = P₂ = 20.2 psi
Initial Volume = V₁ = 0.475 L
Final Volume = V₂ = 1.054 L
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹,
Taking number of moles and R constant we can have following formula for initial and final states,
P₁ V₁ / T₁ = P₂ V₂ / T₂
Solving for T₁,
T₁ = P₁ V₁ T₂ / P₂ V₂
Putting values,
T₁ = (18.7 psi × 0.475 L × 465 K) / (20.2 psi × 1.054 L)
T₁ = 194 K

Explanation:
The amount of rainfall would have the greatest impact on the amount of water available for people in this area. The more the rainfall the more water soaks through layers of porous rocks.Hence, level of water table will remain sufficient for easy pumping of water to the homes.Texas receives plenty of rainfall in a year.In a single year the region can receive up to 48 inches (1,200 mm) of precipitation, and flooding is common near rivers and in low-lying areas. Therefore water table remains intact throughout the year.
