You cool a hot piece of iron by dropping it in cool water. which statement incorrectly describes what is happening? a) after enough time, the final temperature of the water and iron will be the same
b) the amount of heat gained by the water equals the amount of heat lost by the iron
c) the temperature of the iron will decrease as the temperature of the water increases
d) the temperature change of the iron will depend on the latent heat of iron

Option d. The temperature change of iron will depend on its latent heat

Explanation:

If the Calorimetry Principle is taken into consideration which says that in case of no heat loss in the surrounding then the reduction in total amount of heat of a hot body is the same as the rise in the total heat of the cold body.

Therefore, iron's temperature change will not depend on its latent heat and will depend on the the other three mentioned factors:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
