Use 𝑇𝐾 = 𝑇𝐶 + 273 to convert temperature measurements.

A laboratory thermometer records a temperature of 152 °C during a heating experiment. State the temperature in kelvin and identify the appropriate equation used for the conversion.

A laboratory thermometer measures the temperature of a chemical reaction mixture at \(127\,^\circ\text{C}\). The mixture is then cooled to \(27\,^\circ\text{C}\) before being further cooled to \(-73\,^\circ\text{C}\). What is the total change in temperature measured in kelvin?

Refer to the experimental scenario below. Identify which temperature recordings in the table are in Celsius and which are in Kelvin, and explain your reasoning.
