Question

A copper sphere of 100 gm mass is heated to raise temperature to 100 degree celcius and is released in water of mass 195 gm and temperature 20 degree celcius in a copper calorimeter. If the mass of calorimeter is 50 gm what will be the maximum temperature of mixture. Specific heat capacity of copper 0.1 cal/g 0 c

Answer 1

Solution :

Heat given = Heat taken

(100)(0.1)(T–75)=(100)(0.1)(45)+(170)(1)(45)

10(T−75)=450+7650=8100

T−75=810

T=885∘C
