Question

Inside a calorimeter, two solutions are mixed and result in an exothermic reaction. Which of the following best illustrates how this reaction affects the water in the calorimeter?

The reaction causes the temperature of the water to increase. The kinetic energy of the water molecules increases.

The reaction has no effect on the water. The kinetic energy of the water molecules remains the same.

The reaction causes the temperature of the water to decrease. The kinetic energy of the water molecules decreases.

The reaction causes the temperature of the water to increase. Then, the w

Answer 1

ohkay...do you know what an exothermic reaction is ?

Answer 2

sort of yeah the opposite of endothermic reaction and endothermic reaction absorbes heat ex: melting chocolate in a car

Answer 3

\(\sf Exo(gives~out) + Thermic(Heat)=Exothermic(Gives~out~heat)\)

Answer 4

So the water will get heated up due to which its temperature will rise. Now a rise in the temperature will increase the thermal kinetic energy of the water molecules.

Answer 5

getting it ?
What will be the correct option ?

Answer 6

yes i am also i didn't relize that the last option was cut off the last one is suppose to say:
The reaction causes the temperature of the water to increase. Then, the water loses heat to the surroundings and the kinetic energy of the water molecules decreases.

and that is the one i think it is

Answer 7

\(\cancel{\bcancel{~}}\)

Answer 8

last option says `kinetic energy of the water molecules decreases.`

Answer 9

oh :'(
okay then i don't could you a hint?

Answer 11

Check the options for the above key lines

Answer 12

The reaction causes the temperature of the water to increase. The kinetic energy of the water molecules increases.
??

Answer 13

yep !

Answer 14

whooo, finally i just noticed that your hint was actually obvious O﹏o heheheeh

Answer 15

thank you!

Answer 16

since the reaction is exothermic..it will release heat. This heat will increase the temperature of water inside. Due to increase in the temperature the kinetic energy of the water molecules will increase.
