Calculate the heat required, in calories, to raise
thetemperature of 100 g of tin from room temp (20 C) to its
meltingpoint, and then to melt it completely.

Respuesta :

Answer:[tex]Q=4450.74\ J[/tex]

Explanation:

Given

mass of tin [tex]m=100 gm[/tex]

Also we know that

specific heat of tin [tex]c_{tin}=0.21 J/gm-^{\circ}C[/tex]

Melting Point of Tin [tex]T=231.94^{\circ}C[/tex]

Heat required to raise the temperature of 100 gm tin is given by

[tex]Q=mc\Delta T[/tex]

where [tex]Q=heat\ added[/tex]

[tex]c=specific\ heat\ of\ tin[/tex]

[tex]\Delta T=change\ in\ temperature[/tex]

[tex]Q=100\times 0.21\times (231.94-20)[/tex]

[tex]Q=4450.74\ J[/tex]
