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?
Anarel [2989]

Energy can be expressed as:

Q = ms dT

where m represents the mass of the block,

s stands for specific heat,

and dT indicates the temperature change.

Among the three blocks, the copper one has the lowest specific heat, resulting in a greater temperature change and subsequently, the highest final temperature.
