Question

question 3. select all true statements regarding temperature conversions. to convert from celsius to fahrenheit, multiply by 1.8 and add 32. kelvin is an absolute temperature scale and does not use negative values. the temperature conversion from fahrenheit to celsius is simply to add 32. 0 kelvin is the absolute zero temperature.

Explanation:

• The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F = 1.8C+32$. So, the statement "To convert from Celsius to Fahrenheit, multiply by 1.8 and add 32" is correct.
• The Kelvin scale is an absolute scale. The lowest temperature on the Kelvin scale is $0\ K$ (absolute zero), and there are no negative values on the Kelvin scale. So, the statement "Kelvin is an absolute temperature scale and does not use negative values" is correct.
• The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{F - 32}{1.8}$, not just adding 32. So, the statement "The temperature conversion from Fahrenheit to Celsius is simply to add 32" is incorrect.
• $0\ K$ (absolute zero) is the lowest possible temperature where all molecular motion theoretically stops. So, the statement "0 Kelvin is the absolute zero temperature" is correct.

Answer:

• To convert from Celsius to Fahrenheit, multiply by 1.8 and add 32.
• Kelvin is an absolute temperature scale and does not use negative values.
• 0 Kelvin is the absolute zero temperature.
