Question

Баллон содержит идеальный газ при температуре Т1 и давлении Р1. Из баллона выпустили 80% газа и 20% остудили. Какое давление установилось в баллоне?

Answer 1

80 відняти 20 дорівнює 60

Answer 2

Calculation of Pressure in the Tank

To calculate the pressure that will be established in the tank after releasing 80% of the gas and cooling the remaining 20%, we can use the combined gas law, which states that the ratio of the pressure, volume, and temperature of a given amount of gas remains constant.

The combined gas law is expressed as:

P1V1 / T1 = P2V2 / T2

Where: - P1 = initial pressure - V1 = initial volume - T1 = initial temperature - P2 = final pressure - V2 = final volume - T2 = final temperature

Given that 80% of the gas is released and 20% is cooled, we can assume the volume remains constant, and the equation can be simplified to:

P1 / T1 = P2 / T2

We are given the initial temperature T1 and pressure P1. We can use this information to calculate the final pressure P2.

Calculation Steps

1. Calculate the final temperature T2 after cooling the remaining 20% of the gas. 2. Use the combined gas law to find the final pressure P2.

Let's proceed with the calculations.
