The heat capacity of a silver coin is 1....

The heat capacity of a silver coin is `1.128 "cal" .^@C^(-1)`, What should be its mass in gram ? (The specific heat of silver is `C=0.0564 "cal g"^(-1) .^@C^(-1)`)

Text Solution

Verified by Experts

Specific heat of silver,
`C=("Heat capacity of the coin" H_C)/"Mass of the coin m"`
`therefore` Mass of the coin `m=H_C/C=1.128/0.0564`= 20 g
