Answer:
The heat capacity of the sample of metal is 664j/kg.°C
Explanation:
Kindly find attached a detailed solution to this question for you reference.
Given data
Mass of sample m1= 0.45kg
Temperature of sample θs= 80°c
Mass of water mw = 0.7kg
Temperature of water θw= 15°C
Specific heat capacity of water Cw=
4200j/kg.°C
Equilibrium Temperature θ3= 21°C
HEAT LOSS BY SUBSTANCE =HEAT GAINED BY WATER
What is Quantity of heat?
Quantity of heat is the amount of heat absorbed or given out by a body Q=mcθ
What is the heat capacity?
Heat capacity is the amount of heat required to raise the temperature of a substance by 1k.The S.I unit is joule per Kelvin J/k
What is specific heat capacity?
The specific heat capacity is the amount of heat required to raise the temperature of 1kg of substance by 1k

Answer:
Explanation:
As we know by first law of thermodynamics that for ideal gas system we have
Heat given = change in internal energy + Work done
so here we will have
Heat given to the system = 2.2 kJ
Q = 2200 J
also we know that work done by the system is given as
so we have
