serg [7]

Answer:

The answer is "-50.424° C".

Explanation:

Given:

Time = 1 hour

TB=?

Formula:

$TB= \frac{-T\times P}{m \times c_i}$

time (T) = 1 hour

= 3600 second

$t=(3600 -t_2)$

Calculating T_B:

$\to T_B= \frac{-(3600 - t_2) 36.6}{0.250 \times 2090}\\$

$= \frac{-(3600 - 2880) 36.6}{522.6}\\\\= \frac{-(720) 36.6}{522.6}\\\\= \frac{-720 \times 36.6}{522.6}\\\\= \frac{-26352}{522.6}\\\\= -50.424 ^{\circ} C$
