Answer:Mass of tin sample
is ≈ 95.7g
Explanation:
This problem bothers on heat calorimetry/capacity of a substance.
Given data
Specific heat capacity of tin
Cp = 0.227 J/g•°C
Initial temperature of tin θ1= 15°C
Final temperature of tin θ2= -10°C
Heat released Q= 543 J
Mass of tin m=
We know that quantity of heat is given as
Q=mcΔθ
Substituting our given data and solving for mass m we have
543= m*0.227*(-10-15)
543= m*0.227*(-25)
543= - 5.675m
m=543/-5.675
= -95.68
Mass of tin is ≈ 95.7g
What is Quantity of heat?
Quantity of heat is the amount of heat absorbed or given out by a body Q=mcθ
