To find the change in temperature needed for the temperature to reach [tex]\(0^{\circ} C\)[/tex] from [tex]\(-12^{\circ} C\)[/tex], follow these steps:
1. Identify the initial temperature: The initial temperature in the morning is given as [tex]\(-12^{\circ} C\)[/tex].
2. Identify the target temperature: The target temperature we want to reach is [tex]\(0^{\circ} C\)[/tex].
3. Calculate the change in temperature: To find the change in temperature, subtract the initial temperature from the target temperature.
[tex]\[
\text{Change in temperature} = 0^{\circ} C - (-12^{\circ} C)
\][/tex]
4. Simplify the expression: Subtracting a negative number is equivalent to adding the positive counterpart of that number.
[tex]\[
0^{\circ} C - (-12^{\circ} C) = 0^{\circ} C + 12^{\circ} C = 12^{\circ} C
\][/tex]
Therefore, the change in temperature needed to reach [tex]\(0^{\circ} C\)[/tex] is:
[tex]\[
\boxed{12^{\circ} C}
\][/tex]
