The specific heat of Aluminum is 0.9 J/g K. The specific heat of Copper is 0.39 J/g K. If samples of equal mass of both Aluminum and Copper are heated up to 100°C and then dropped in a cold water bath. Compare the heat lost by the two samples.

Answer:The Aluminum loses a little more than twice the heat of the Copper.Explanation:
Since specific heat is part of the equation. A smaller specific heat will create a smaller heat gain or loss.

Answer:

Heat loss by aluminium will be more as compare to copper.

Step-by-step explanation:

We know that heat lost given as follows


Q=mC_p\Delta T

Given that mass of aluminium and copper are same so lets take 1 g.

Lets take the temperature of cold water is 10°C

For aluminium


Q=mC_p\Delta T


Q=1* 0.9* 90

Q= 81 J

For copper


Q=mC_p\Delta T


Q=1* 0.39* 90

Q= 35.1 J

So from above we can say that heat loss by aluminium will be more as compare to copper.
