Final answer:
The temperature change from -2 °C to -10 °C is calculated as -10 °C - (-2 °C), resulting in a negative change of -8 °C, indicating a decrease in temperature.
Step-by-step explanation:
The student's question involves a simple calculation of the change in temperature, which is a mathematical concept. When the temperature falls from -2 °C to -10 °C, the change in temperature is calculated by subtracting the final temperature from the initial temperature: -10 °C - (-2 °C) = -10 °C + 2 °C = -8 °C. The negative sign indicates the change is a decrease in temperature.
The change in temperature would be negative, as the temperature has fallen (decreased). To find the change in temperature, you subtract the initial temperature from the final temperature: Change in temperature = Final temperature - Initial temperature = -10 °C - (-2 °C) = -10 °C + 2 °C = -8 °C. Therefore, the temperature has changed by -8 °C.
