100g of an unknown metal at 150°C was dropped into a bucket containing 50g of water initially at 21°C.The final temperature of the mixture was 32°C.What is the specific heat capacity of the unknown metal?
Taking specific heat capacity of water as "4200J\/(Kg.K)"
Let c"=" specific heat capacity of the metal
Heat lost by metal":"
"=\\frac{100}{1000}\u00d7c\u00d7(150-32)"
"=11.8cJ"
Heat gained by water
"=\\frac{50}{1000}\u00d74200\u00d7(32-21)"
"=2310J"
"11.8c=2310"
"c=195.76J\/(Kg.K)"
