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.

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

Explanation:

We know that heat lost given as follows

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= 81 J

For copper

Q= 35.1 J

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

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
