Final Temperature in Heating Applesauce. A mixture of 454 kg of applesauce at 10°C is heated in a heat exchanger by adding 12130

jok3333 [9.3K]

Answer:

$T_f = 76.46°C$

Explanation:

Given data:

Mass of mixture = 454 kg

Initial temperature is 10°C

Heat added is Q = 121300 kJ

Heat capacity (Applesuace) at 32.8°C is 4.02kJ/kg K

From heat equation we have

$Q = mCp(T_f -T_i)$

$\frac{Q}{mCp} = (T_f -T_i)$

$T_f = T_i + \frac{Q}{mCp}$

Putting all value to get required final temperature value

$T_f = \frac{121300}{454\times 4.02} + 10$

$T_f = 76.46°C$

How does the Sun get energy?

Nikolay [14]

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.
