You have collected exactly 1600 aluminum cans for recycling, each with a mass of 14.2 g. how much energy is needed to melt them if their initial temperature is 26.3â¦c? assume the specific heat, the latent heat and the melting point of aluminum are 899 j/kg â·â¦ c,
3.97 ã 105 j/kg and 660.4 â¦c, respectively. answer in units of j.

The heat requied is

Explanation:

According to the given data

1) Initial temperature of can =

2) Specific Heat of Aluminum can =

3) Latent Heat of Aluminum can =

4) Melting point of of Aluminum can =

5) Toatl mass of of Aluminum can =

Now in order to melt the can we first need to raise it's temperature from to

Thus the ensergy required is calculated as

Now the heat required to change the phase from solid aluminum to liquid phase can be calculated as

Thus the total heat required is
