Exciting Science Experiment with Butane and Propane Tanks!

Are These Statements True or False?

1. The pressure reading for the butane tank is higher than that for the propane tank.

2. The pressure readings will change when more liquid is added to the tanks.

3. If the tanks are placed outside and the sun warms each tank to 46°C, the pressure readings will be higher than they were initially.

4. If an equal number of moles of gas is allowed to escape rapidly from each tank, the temperature of the butane tank will be lower than that of the propane tank.

Answers:

1. False

2. False

3. True

4. True

Let's dive into the exciting world of chemistry with an experiment involving butane and propane tanks! In this experiment, we will explore the pressure readings and temperature changes of these two substances.

Pressure Readings:

The statement that the pressure reading for the butane tank is higher than that for the propane tank is actually false. Both tanks have their own pressure readings based on the substance inside.

The pressure readings will not change when more liquid is added to the tanks. This is because the pressure is determined by the amount of gas in the tank, not the liquid.

Temperature Changes:

If the tanks are placed outside and the sun warms each tank to 46°C, the pressure readings will indeed be higher than they were initially. This is due to the increase in temperature causing the gas inside to expand.

When an equal number of moles of gas exits rapidly from each tank, the temperature of the butane tank will be lower than that of the propane tank. This is because the rapid decrease in gas molecules leads to a decrease in temperature.

Get ready to conduct this fascinating experiment and witness the science in action!
