The work done by gas is 0.753 J and change in internal energy is 4.247J
So we are given that mass is 2kg , radius 1 cm and the amount of heat is 5 cm
The piston raised by 2.4cm
As we know that Work done is PΔV
Where ΔV is change in volume
Therefore ΔV = πr^2 h = π x (.01)^2 x .024 =7.53×10^(-6)m^3
Here pressure is 10^5 pa
So W = 
Therefore W = 0.753 J
Now coming to change in internal energy
Change in Internal Energy = Heat Added - Energy lost in work
∴ 5J - 0.753 J = 4.247J
Hence the change in internal energy is 4.247 J

Answer:
Weight of cow = 7.59 lbs
Explanation:
Given:
Weight of cow = 1518 lbs
Find:
Weight of heart of a cow
Computation:
Note: It is not given that in the mammals the weight of heart is approximately 0.5% of total body weight
Weight of heart of a cow = [Weight of cow][0.5%]
Weight of cow = [1518][0.5%]
Weight of cow = 7.59 lbs
