How much heat is required to increase the temperature of 198.5 grams of water from 25.0 oc to 88.5 oc? (the specific heat of water is 4.18 j/g x oc)

a.52, 700 j
b.199 j
c.265 j
d.73,400 j
e.20,700 j

Answer : The correct option is, (A) 52700 J

Solution :

Formula used :

Q = heat gained

m = mass of the substance = 198.5 g

c = heat capacity of water = 4.18 J/g°C      

Now put all the given values in the above formula, we get

Q = 52687.855 J ≈ 52700 J

Therefore, the amount of heat required is, 52700 J

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
