Answer:

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An ethothermic process absorbs heat and cools the surroundings. Hope this helped.

The easiest way to explain endo and exothermic reactions are that endothermic reactions absorb energy and exothermic reactions release energy.

The way I remember this is that with <u>ex</u>othermic reactions, the heat <u>ex</u>its. Endothermic is just the opposite.

Hope this helps :)

Answer:

$c=2.0769\ \frac{J}{g\ \textdegree C}$

Explanation:

-Specific heat capacity is given by the formula:

$q=mc\bigtriangleup T$

Where:

$q$ is the heat gained or loosed by the substance

$m$ is the mass of the substance

$c$ is the specific heat of the substance

$\bigtriangleup T$ is the change in temperature

#We make c the subject of the formula and substitute to solve for it:

$q=mc\bigtriangleup T\\\\c=\frac{q}{m\bigtriangleup T}\\\\\bigtriangleup T=(57-32)\textdegree C=25\textdegree C\\\\\therefore c=\frac{6.75\times 10^4J}{1.3\times 1000\ g\times 25\textdegree C}\\\\=2.0769 \ \frac{J}{g\ \textdegree C}$
