To find the change in temperature between 9:00 a.m. and noon, we need to subtract the temperature at noon from the temperature at 9:00 a.m.
Let's define the temperatures:
- Temperature at 9:00 a.m. = \( T_1 = 95.8^\circ C \)
- Temperature at noon = \( T_2 = -1.6^\circ C \)
The change in temperature (\( \Delta T \)) can be calculated using the equation:
\[ \Delta T = T_2 - T_1 \]
Substituting the values:
\[ \Delta T = -1.6^\circ C - 95.8^\circ C \]
Now, let's perform the calculation:
\[ \Delta T = -1.6 - 95.8 = -97.4 \]
So, the change in temperature is:
\[ \Delta T = -97.4^\circ C \]
Explanation of the Answer:
The negative sign indicates that the temperature has decreased. A change of \(-97.4^\circ C\) means that the temperature dropped significantly from 95.8° C at 9:00 a.m. to -1.6° C at noon. This dramatic decrease in temperature could suggest a major weather event or a significant change in environmental conditions during that time period.
