The boiling point of ethane is 88 degrees Celsius. This temperature will be equal to…
The correct answer and explanation is:
The boiling point of ethane (C2H6) is actually -88 degrees Celsius, not +88°C. If you meant to convert this temperature to other units, here is the correct conversion to Kelvin and Fahrenheit:
Given:
- Boiling point of ethane = -88°C
Convert Celsius to Kelvin (K):
K=°C+273.15K = °C + 273.15 K=−88+273.15=185.15 KK = -88 + 273.15 = 185.15 \text{ K}
Convert Celsius to Fahrenheit (°F):
°F=(°C×95)+32°F = (°C \times \frac{9}{5}) + 32 °F=(−88×95)+32=(−158.4)+32=−126.4°F°F = (-88 \times \frac{9}{5}) + 32 = (-158.4) + 32 = -126.4°F
Summary:
- Boiling point of ethane = -88°C
- Boiling point of ethane = 185.15 K
- Boiling point of ethane = -126.4°F
Explanation:
Ethane is a simple hydrocarbon with the molecular formula C2H6. It is a nonpolar molecule, which means its intermolecular forces are mainly weak London dispersion forces. These weak forces lead to a very low boiling point compared to polar or hydrogen-bonded molecules.
The boiling point is the temperature at which a substance changes from liquid to gas under atmospheric pressure (1 atm). For ethane, this temperature is -88°C, indicating it boils at a very low temperature and exists as a gas at room temperature.
Temperature scales like Celsius, Kelvin, and Fahrenheit are used for different scientific and everyday applications:
- Celsius (°C) is widely used in most countries and science labs.
- Kelvin (K) is the SI unit for temperature and used primarily in physics and chemistry because it starts at absolute zero (the theoretical point where all molecular motion stops). The Kelvin scale avoids negative numbers, making it convenient for scientific calculations.
- Fahrenheit (°F) is mostly used in the United States for weather and cooking.
Knowing how to convert between these scales is essential for understanding temperature-dependent processes in chemistry and physics
