Explanation:
The given data is as follows.
Spring constant (k) = 78 N/m, 
Mass of block (m) = 0.50 kg
According to the formula of energy conservation,
mgh sin 
h = 
= 
= 0.64 m
Thus, we can conclude that the distance traveled by the block is 0.64 m.

(a) The work done by the gas during the isothermal expansion is -25.6 J.
(b) The heat added to the gas during this process is 25.6 J.
<h3>
Net work done by the ideal gas against the external pressure</h3>
The net work done by the ideal gas in the isothermal expansion is calculated as follows;
W(net) = ΔP x ΔV
W(net) = ( 1 kPa - 5 kPa) x (8L - 1.6 L)
W(net) = -25.6 kPa.L
W(net) = -25.6 J
<h3>Head added to the gas</h3>
The heat added to the gas is calculated as follows;
W = -Q
-25.6 J = -Q
Q = 25.6 J
