Question

If 75.0 J of heat energy are added to separate 25.0 g samples of gold (C = 0.129 J/g°C), silver (C = 0.234 J/g°C), aluminum (C = 0.895 J/g°C), chromium (C = 0.450 J/g°C), and copper (C = 0.377 J/g°C), rank the metals in order from least to greatest final temperature. Cr < Cu < Al < Ag < Au

Answer 1

Answer: Al < Cr < Cu < Ag < Au

Step-by-step explanation:

Specific heat tells us how much heat energy is needed to raise the temperature of 1g of the substance by 1 K.

Adding equal amounts of heat will produce the highest temperature rise in the metal with the lowest specific heat capacity.

Therefore metals from the least to greatest will be ,

Al < Cr < Cu < Ag < Au
