OnRamps Lab 5: Molar Determination of Gas - CER Guidance
What should you do to maintain proper volume in your car tires during the cold of winter, pump extra air in or release air out?
I. Claim: The "C" part of the CER
II. Evidence: The "E" part of the CER
III. Reasoning: The "R" part of the CER

Answer 1

During winter due to low temperatures, Pressure inside and outside tires varies as the relationship between pressure and temperature are inversely proportional.

I. Claim:

To maintain proper pressure in car tires during the cold of winter, we should have sufficient extra air inflated in or check and balance the tire pressure according to the pressure guidelines recommended by the company.

II. Evidence:

As the temperature and pressure are inversely propotional to each other, if temperature drops in the atmosphere as during winter, the air inside the tires shrink, causing the tire pressure to decrease. This can lead to low pressure level in tires, which can result in Burning of more fuel, and increased tire wear and tear.

III. Reasoning:

Always checking extra air to car tires to a recommended levelduring cold weather conditions ensure balance pressure inside the cars tire and outside of environment.

Answer 2

Answer:

Answer explained below

Explanation:

I. Claim: To maintain proper volume in your car tires during the cold of winter, you should release air out of your tires.

II. Evidence: When the temperature drops, the air inside your tires contracts and takes up less space, leading to a decrease in tire pressure. As a result, your tires may become underinflated, which can negatively affect your car's handling and fuel economy. According to the Rubber Manufacturers Association, for every 10-degree drop in temperature, tire pressure decreases by one to two pounds per square inch (PSI). Therefore, to maintain proper tire pressure during the winter, you should release air out of your tires.

III. Reasoning: Releasing air out of your tires is necessary during the cold of winter to ensure that your tires are not underinflated, which can cause safety issues and negatively impact your car's performance. Keeping your tires at the recommended pressure level will ensure that they grip the road properly, and your car handles well in harsh winter conditions. Therefore, it is important to check your tire pressure regularly during the winter and release air if necessary to keep your tires properly inflated.
