What is the temperature of the heated gas? - ProProfs Discuss

# What is the temperature of the heated gas? A gas is confined in a steel tank with a volume of 6.982 L. At 20.20Â°C, the gas exerts a pressure of 8.532 ATM. After heating the tank, the pressure of the gas increases to 10.406 ATM.

The temperature of the heated gas is 84.59c. This is because there are certain laws governing gases. The pressure, volume and the temperature are all linked. Now that the volume is made constant, the pressure is directly related to the temperature of the gas. This means that as the pressure on the gas increases so does the temperature.

As the pressure will make the gas molecules come close together they will bump more with each other. Ultimately, this will lead to excessive temperature which causes the pressure of the gas to rise further. This is why you need to take particular care of gases contained in pressurized containers.

To solve this problem remember one thing: the volume will remain constant because the gas is placed in a steel tank. The formula you need to follow is: P1/T1 = P2/T2. Input all of the needed details and you will reach the answer 84.59 Degrees Celsius which is letter C in the choices. The gas pressure will increase because of kinetic energy.

When the molecules are required to move, they would try their best to move around to supposedly get out of the container. Since they are confined to the container however, they would keep on bumping around. As they continue moving, the pressure will start to increase. There are moments when they bump around so much that the enclosed container succumbs to the pressure and blows up.

Based on the given details above, the answer to this question is 84.59 Degrees Celsius. As the temperature of the heated gas increases, the pressure of the gas molecules also increase. The molecules of heated gas have the tendency to move faster than before.

They will bump into each other and just go towards different directions. This can increase the pressure even more. This explains why some flammable and explosive materials start to explode when they are situated in areas wherein the temperature is hot. Gas that is placed in a sealed container will always have the possibility of exploding especially as the temperature increases further.
