A bubble of 8 mole of helium is submerged at a certain depth in water. The temperature of water increases by \( 30^{\circ} \mathrm{C} \). How much heat is added approximately to helium during expansion
[Kerala PET 2008]
(a) \( 4000 \mathrm{~J} \)
(b) \( 3000 \mathrm{~J} \)
(c) \( 3500 \mathrm{~J} \)
(d) \( 4500 \mathrm{~J} \)
(e) \( 5000 \mathrm{~J} \)
