FALSE
Answer:
True
Explanation:
The boiling point of a liquid is the temperature at which the vapour pressure of the liquid equals the pressure of the surrounding atmosphere.
When a liquid is heated, the vapour pressure gradually increases till it matches the ambient pressure. Gas bubbles begin to form within the liquid, rise to the surface and then burst up to release gas. At this point, we say the liquid is boiling.
The lower the surrounding pressure, the lower the boiling point of a liquid and vice versa. Water boils at lower temperature in high altitudes because of lower pressure as compared to sea level.

Answer:
To determine the relationship between pressure and temperature in this scenario, we can use the ideal gas law.
The ideal gas law states that PV = nRT, where P represents pressure, V represents volume, n represents the number of moles of gas, R is the ideal gas constant, and T represents temperature in Kelvin.
Since we only have the initial and final pressures and temperatures, we can compare them using the ideal gas law equation by setting up the following ratio:
(P₁T₁) / (P₂T₂) = (V₁n₁R) / (V₂n₂R)
Since the volume, number of moles, and gas constant remain constant, we can simplify the equation:
(P₁T₁) / (P₂T₂) = 1
Now, we can substitute the given values into the equation:
(53.0 atm * T₁) / (35.2 atm * 12.0°C) = 1
To solve for T₁, we need to convert 12.0°C to Kelvin by adding 273.15:
(53.0 atm * T₁) / (35.2 atm * (12.0 + 273.15) K) = 1
Simplifying the equation further:
(53.0 atm * T₁) / (35.2 atm * 285.15 K) = 1
Now, we can solve for T₁:
(53.0 atm * T₁) = (35.2 atm) * (285.15 K)
Dividing both sides of the equation by 53.0 atm:
T₁ = (35.2 atm * 285.15 K) / 53.0 atm
Calculating the numerical value:
T₁ ≈ 189.5 K
Therefore, when the pressure changes from 53.0 atm to 35.2 atm, the temperature changes from approximately 12.0°C to 189.5 K.
