• Flask 1 contain the most molecules
• Flask 2 contain the most molecules
• Flask 3 contain the most molecules
• Flask 4 contain the most molecules

• Since all flask have same amount of gas, flask 1 has the least pressure
• Since all flask have same amount of gas, flask 2 has the least pressure
• Since all flask have same amount of gas, flask 3 has the least pressure
• Since all flask have same amount of gas, flask 4 has the least pressure

• Flask 1 contain the least pressure
• Flask 2 contain the least pressure
• Flask 3 contain the least pressure
• Flask 4 contain the least pressure
