Detailed Solution

Apparent weight=True weight minus upthrust

$m g' = m g - V_{b} ρ_{l} g$

When the system is heated,

$m g'' = m g - [V_{b} (1 + γ_{b} θ)] [\frac{ρ_{l}}{1 + γ_{l} θ}] g = m g - V_{b} ρ_{l} g \frac{(1 + γ_{b} θ)}{1 + 2 γ_{b} θ}$

Clearly, $m g'' > m g'$ . Apparent weight increases.
