The amount of heat energy added to silver to heat it from 25°C to 100°C is :

8737.5 J

<u>Given data: </u>

mass of silver ( m ) = 500 g

T1 = 25°C

T2 = 100°C

s ( specific heat of silver ) = 0.233 J/g.c

<h3 /><h3>Determine the amount of heat required </h3>

Applying the formula below for heat ( Q )

Q = ms * ΔT

= 500 * 0.233 * ( 100 - 25 )

= 8737.5 J

Hence we can conclude that the The amount of heat energy added to silver to heat it from 25°C to 100°C is : 8737.5 J.

d. exothermic; leaving

Exothermic reaction is a reaction that produces heat in the reaction whereas the endothermic reaction is a reaction in which heat is required to be given in the reaction to produce product.
Fire is an exothermic reaction.
A fire is produced due to oxidation of the fuel in the form of liquid or gas.
A fire is an example of combustion.
In fire both heat and light are left from fire due to the oxidation of fuel.

Hence, option d. exothermic; leaving is the correct option.
