Three separate 3.5g blocks of al, cu, and fe at 25°c each absorb 0.505 kj of heat. which block reaches the highest temperature? the specific heats of al, cu, and fe are 0.900 j/g·°c, 0.385j/g·°c, and 0.444 j/g·°c, respectively.

The energy can be shown as:

Q = ms dT

Whereas, m is the mass of block

s is specific heat

dT is change in temperature.

Copper block having the lowest specific heat and thus having the higher change in temperature and therefore having the higher final temperature.

c. 75.7

i think that is the right

the answer is 0.8m.
