Which 10.0 cube of metal at 65 , when added to 30.0 water at 25 , will result in the least temperature rise for water?

b Silver
c Copper
d Aluminum

Answer 1

you have to looks in a specific heat capacity table and find the values of specific heat capacity for your metals
http://en.wikipedia.org/wiki/Heat_capacity#Table_of_specific_heat_capacities

then using the formula q (met)= -q (H2O)
q= m x C x delta T
the T final is the same
you calculate the T final for each of the metals that you have (looks the attachment )or you can do just the one with the highest and the one with the lowest C, and then compare which one will result in the least temperature rise for water. Then you can make your conclusion and relate the higher the C how is going to affect the final temperature
