Answer:
T₂ = 721 k
Explanation:
Given data:
Initial volume = 285 mL
Initial pressure = 1.88 atm
Initial temperature = 355 K
Final temperature = ?
Final volume = 435 mL
Final pressure = 2.50 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁ / P₁V₁
T₂ = 2.50 atm × 435 mL × 355 K / 1.88 atm × 285 mL
T₂ = 386062.5 atm. mL. K /535.8 atm. mL
T₂ = 721 k
Electrostatic forces work on anything that is charged.

I might need a diagram for this, but I have a vague idea of what you are talking about.
If H20 is going left it means the temperature is going lower.
The molecules will condense to slowly become ice
A. pH meter is the instrument which will provide the most direct measure of pH by measuring the hydrogen ion concentration of a solution.
Litmus paper is just a paper which changes color based on whether the solution is an acid or a base. Phenolphthalein is an indicator which changes color based on pH values. And bromthymol blue doesn't tell concentrations, it is just a pH indicator for weak acids and bases.
For hydrogen-like atom electron transition from n=3 to n=5, it would be classified as an absorption of energy. For hydrogen-like atom electron transition from <span>n=3 to n=2, it would be classified as an emission of energy. Hope this helps. Have a nice day.</span>
