Question

In chemistry students will make their temperature measurements in the lab with a thermometer with the Celsius scale. However, in their studies using Gas Laws, all measurements must be converted to the Kelvin scale. If a student measures a gas in the lab and finds the temperature to be 18 degrees Celsius, what temperature Kelvin will the student use for their calculations?

Answer 1

For gas law calculations in chemistry, temperatures in Celsius must be converted to Kelvin by adding 273.15. Thus, a lab temperature of 18 degrees Celsius is equivalent to 291.15 Kelvin.

Step-by-step explanation:

When conducting experiments involving gas laws, it's essential to use the Kelvin temperature scale for measuring temperature. To convert a temperature from the Celsius scale to the Kelvin scale, one needs to add 273.15 to the Celsius temperature. Therefore, if a student measures a gas temperature as 18 degrees Celsius in the lab, for calculations involving gas laws, they will use a temperature of 291.15 Kelvin (18 °C + 273.15 = 291.15 K).
