Answer:
The answer is "-50.424° C".
Explanation:
Given:
Time = 1 hour
TB=?
Formula:
[tex]TB= \frac{-T\times P}{m \times c_i}[/tex]
time (T) = 1 hour
= 3600 second
[tex]t=(3600 -t_2)[/tex]
Calculating T_B:
[tex]\to T_B= \frac{-(3600 - t_2) 36.6}{0.250 \times 2090}\\[/tex]
[tex]= \frac{-(3600 - 2880) 36.6}{522.6}\\\\= \frac{-(720) 36.6}{522.6}\\\\= \frac{-720 \times 36.6}{522.6}\\\\= \frac{-26352}{522.6}\\\\= -50.424 ^{\circ} C[/tex]
