Answer to Question #203970 in General Chemistry for Lorraine Joy River

Question

Activity # 1

1. You found a piece of copper metal weighing 3.10 g 

imbedded in an ice block. How much heat is absorbed by 

the piece of metal as it warms in your hand from the 

temperature of the ice block at 1.5 oC to your body 

temperature of 37.0 oC? The specific heat of copper is 

0.385 J/g- oC. Assume that the metal is pure coppe

Answer 1

Solution

Calculating the heat absorbed

Q=mS∆T

m= mass of sample in grams

S= specific heat capacity of the sample

∆T= change in temperature

Q= 3.10$\times0.385\times(37.0-1.5)$

Q= 42.37J
