Final Exam Honors Chemistry 2025 - States of Matter and Gas Laws

Ethan and Avery are curious about the pressure inside a can of Dr Pepper. Which instrument should they use to measure the pressure inside the can?

• barometer

• manometer

• vacuum pump

• torrometer

Matthew and Nicole are in the chemistry lab, and they've just set up a fun experiment using Dr Pepper and a manometer! The manometer is filled with Dr Pepper instead of mercury (but somehow Dr Pepper has the same density as Mercury), and they need your help to calculate the pressure of the confined gas (p). If the atmospheric pressure is 698 torr and h is equal to 2.50 cm, can you help Matthew and Nicole figure out the pressure of the gas?

• 673 mm Hg

• 695.5 mm Hg

• 700.5 mm Hg

• 723 mm Hg

Imagine you have a sealed can of Dr Pepper, and you are watching the gas molecules inside the can zoom around. What does the constant bombardment of these molecules against the inside walls of the can create?

• temperature

• density

• pressure

• diffusion

Emily and Alex are discussing why a can of Dr Pepper keeps its shape and has a definite volume. Can you help them figure it out?

• the particles are far apart.

• the intermolecular forces between molecules are very strong.

• they can be easily compressed since they are weakly attracted to each other.

• the energy of the particles is high.

Ellee and Drew are doing a science experiment. They use a vacuum pump to remove air from a can of Dr Pepper. Suddenly, the can collapses! Why did this happen?

• The inside and outside forces balance out and crush the can.

• The unbalanced outside force from atmospheric pressure crushes the can.

• The atmosphere exerts pressure on the inside of the can and crushes it.

• The vacuum pump creates a force that crushes the can.

Krista just bought a can of Dr Pepper and sees that it's been stored at 38°C. She wants to tell her friend Drew what the temperature is in Fahrenheit. Can you help Krista and Drew by selecting the correct value for 38°C?

• 70°F

• 126°F

• 100.4°F

• 311°F

Gianna and Parker are at a Dr Pepper bottling plant, and they need to convert the pressure reading of 0.75 atm inside a can of Dr Pepper to mm Hg for their quality control experiment. Can you help them figure out the correct value?

• 101.325 mm Hg

• 430 mm Hg

• 570 mm Hg

• 760 mm Hg

Sam and Victoria are organizing a Dr Pepper tasting event, and they need to convert the pressure inside a can of Dr Pepper, which is 2.50 atm, to kPa. Can you help them figure it out?

• 1 kPa

• 253 kPa

• 760 kPa

• 1000 kPa

Gianna is conducting a science experiment with a can of Dr Pepper. The volume of the gas inside the can is 400.0 mL when the pressure is 1.00 atm. At the same temperature, Gianna wants to know: what will the pressure be if she expands the volume of the gas to 2.0 L?

• 0.20 atm

• 0.50 atm

• 5.0 atm

• 200 atm

Parker and Victoria are conducting a science experiment with Dr Pepper! They have a 0.500 mole sample of Dr Pepper gas with a volume of 11.2 L at 273 K. Can you help them figure out what the pressure of the Dr Pepper gas is?

• 11.2 torr

• 273 torr

• 380 torr

• 760 torr
