Depends... did you measure your object to cool down or heat up? If it heated up, then is #T_2 > T_1#, or #T_2 < T_1#? If it cooled down, then is #T_2 < T_1#, or #T_2 > T_1#?

Always connect observations back to physical reality. Is #DeltaT# negative or positive if #T_2 = "320 K"# and #T_1 = "300 K"#?
