Ksenya-84 [330]
Hello!

According to the Charles' Law, the volume of a gas is proportional to temperature when pressure is constant. When going from New York to Florida, if the pressure is left constant the volume of the tires will increase.

The final volume of the tires can be calculated from the following equation, derived from Charles' Law:

V2= \frac{V1}{T1}*T2=\frac{10 L}{10degC}*32degC=32 L

Have a nice day!

A 1.0 L volume of gas at 27.0°C exerts a pressure of 85.5 K PA what will the pressure be at 127°C assume constant volume
Marianna [84]

Answer:

114 kPa

Explanation:

Using Gay-Lussac's law you get the equation \frac{P1}{T1} x \frac{P2}{T2} and converting celcius you get the final equation of \frac{85.5}{27+273}  x \frac{P2}{127+273} . After dividing 85.5 by 27+273(300) you get 0.285 and then you multiply 0.285 by 127+273 (400). You finally get 114 kPa

The point of a scientific experiment is to find the answer to a question. If a scientist performs an experiment only one time, they might find an answer to their question. However, they might have messed something up, so the answer is completely wrong. Doing an experiment momre than once can help a scientist make sure that their answer is correct. I hope this helps!
