Question

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.

Answer 1

Answer:
`Q=4450.74\ J`

Step-by-step explanation:

Given

mass of tin
`m=100 gm`

Also we know that

specific heat of tin
`c_(tin)=0.21 J/gm-^(\circ)C`

Melting Point of Tin
`T=231.94^(\circ)C`

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

`Q=mc\Delta T`

where
`Q=heat\ added`

`c=specific\ heat\ of\ tin`

`\Delta T=change\ in\ temperature`

`Q=100* 0.21* (231.94-20)`

`Q=4450.74\ J`
