At what temperature will a fixed amount of gas with a volume of 175 l at 15 degrees celsius and 760mmhg occupy a volume of 198l at a pressure of 640mmhg?

T₂ = 274.5 K = 1.35 °C

Explanation:

Given: V₁ = 175 L, P₁ = 760 mmHg, T₁ = 15°C = 288.15 K (∵ 1°C=273.15 K)

V₂ = 198 L, P₂ = 640 mmHg, T₂ = ? K

To calculate T₂, we use the General Gas Equation:

Therefore, T₂ = 274.5 K = 1.35 °C

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
