Question

A metal alloy bolt is initially at 100.0 degrees * C . It is dropped into a coffee cup calonmater Containing 50.0 g of water at a temperature of 20.0*C. After stirring, the final temperature both bolt and water is 25.0 degrees * C . Assuming no heat losses, and that the specific heat capacity of water is 4.18J / (g - K) what is the heat capacity of the boltin nd / K ?

QUESTION 5 A metal loy bolt is initially at 1000 G. It is dropped into a coffee cup calorimeter containing 500 g of water at a temperature of 20.00. After sting, the Snaterrperature of both bolt and water is 25.0'C. Assuming no how losses, and that the specifichest capacity of water is 418.g.), what is the heat capacity of the bolt in JK? A279 JK B33JX 13 JK D.200K None of these choice is correct.

Answer 1

Bolt wale Ti= 100°c m=sog To=25°c. Ti = 20°C a stw = 50 OT = 25-100 19 220 2 = -75°C Се: 4:13 314 +375 €) heat released by bolt = heat gained by water Creleased : .-ve) ve -CATE = mcp ato с = м се до -DT = 50 x 4.18*5 = 13.95/K |-|-75)
