A small ball is immersed in water. It weighs w1, at 0°C. Water is heated to 50°C and now it weighs w2. The coefficient of cubical expansion of ball material is less than water then on comparing weights,

 A small ball is immersed in water. It weighs w1, at 0°C. Water is heated to 50°C and now it weighs w2. The coefficient of cubical expansion of ball material is less than water then on comparing weights,

	w2 > w1
	w2 < w1
	w1 = w2
