Short answer

The boiling point of liquid oxygen is -297.4°F, -183°C, and 90.15K.

Step-by-step solution

Conducting a Search

Use a search engine such as Google or Yahoo to find reliable sources about the boiling point of liquid oxygen. Type 'boiling point of liquid oxygen' into the search bar and review the summaries of listed results.

Identifying a Reliable Source

Choose a link from a credible source such as a university, scientific journal, or a reputable scientific organization's website. For instance, websites ending in .edu, .org, or .gov often provide accurate information. Open the link to find detailed information about liquid oxygen.

Extracting the Data

Read the content of the selected source to gather the required data. Typically, the boiling point of liquid oxygen is listed in Celsius. Make a note of the boiling point in Celsius, and proceed to gather how it may be noted in Fahrenheit and Kelvin as well.

Recording the Boiling Points

Document the boiling point of liquid oxygen from the source in Celsius. Then, note any additional temperature units provided. For instance, the boiling point of liquid oxygen is often given as -183°C.

Converting to Other Units

If the source did not provide temperatures in all desired units, use the following conversions: - To convert Celsius to Fahrenheit: \[ F = C \times \frac{9}{5} + 32 \]- To convert Celsius to Kelvin: \[ K = C + 273.15 \]For -183°C, the Fahrenheit equivalent is -297.4°F, and the Kelvin equivalent is 90.15K.

Citing the Source

Prepare a reference citation for the source from which the boiling point data was obtained. This should include the URL, and the date accessed if possible. E.g., "Source: National Institute of Standards and Technology, accessed October 15, 2023, from https://www.nist.gov"

Key concepts

Liquid Oxygen

Liquid oxygen is an interesting and essential form of oxygen used widely in science and industry. When oxygen turns into a liquid form, it is pale blue and extremely cold. The boiling point of liquid oxygen is quite low, sitting at -183°C. This temperature is way below freezing, and it is crucial for processes where low-temperature conditions are required, such as in rocket propulsion and medical purposes.

• At -183°C, liquid oxygen transitions from a liquid to a gaseous state, making it useful in controlled environments.
• It is important to handle liquid oxygen with care due to its extremely low boiling point and strong oxidizing properties.
• When dealing with liquid oxygen, one must ensure the surroundings are non-reactive, as it can react violently with organic materials and combustibles.
• This form of oxygen can be stored and transported in cryogenic tanks.

Understanding its boiling point is vital for safe handling and practical applications.

Temperature Conversion

Temperature conversion is a handy skill, especially when dealing with scientific data across different standards. Often, measurements are given in Celsius, Fahrenheit, or Kelvin, necessitating conversions to compare like with like. When calculating the boiling point of liquid oxygen, it’s useful to know how to convert its temperature between these units.

• Celsius to Fahrenheit involves multiplying by 9/5 and adding 32. For example, -183°C is equal to -297.4°F. The formula is: \[ F = C \times \frac{9}{5} + 32 \]
• Celsius to Kelvin is straightforward: simply add 273.15. Thus, -183°C is equivalent to 90.15K. The formula is: \[ K = C + 273.15 \]

Temperature conversion ensures that we can communicate scientific data clearly and effectively.
It allows researchers and engineers globally to ensure consistency and understanding, no matter which temperature scale is in use.

Scientific Methodology

Scientific methodology is the backbone of reliable and repeatable research. When exploring the boiling point of liquid oxygen, following a structured approach ensures that findings are accurate and verifiable.

• Start with research. Use credible sources, such as scientific journals or reputable websites in the .edu, .org, or .gov domains.
• Collect accurate data. For instance, obtaining the correct boiling points in multiple units involves careful sourcing and conversion.
• Ensure reproducibility. Record steps and calculations meticulously for others to verify and reproduce.
• Always cite sources correctly. This adds credibility to your work and allows others to follow the research trail.

Embedding scientific methodology in your research gives your work integrity and reliability.
It ensures that scientific exploration of topics like the boiling point of liquids is grounded, transparent, and open to verification.
