Concept explainers
Alloys When a 58.8-g piece of hot alloy is placed in125 g of cold water in a calorimeter, the temperature ofthe alloy decreases by 106.1°C, while the temperature ofthe water increases by 10.5°C. What is the specific heat ofthe alloy?
Interpretation:
Specific heatof alloy is to be described.
Concept introduction:
Specific heat: It is the amount of heat required to raise the temperature of an substance by
Answer to Problem 78A
Specific heat of the alloy is
Explanation of Solution
Since,
Relation between mass, temperature and specific heat.
C is the specific heat
Since, heat transfers from one substance to the other, then q must be equal in magnitude, but opposite in direction for each substance.
