Shabnam put something in a vessel of water and heated it on a gas stove for 30 minutes. That thing looked the SAME even after 30 minutes of heating. What could she have put into the vessel? A) a steel spoon B) a wax candle C) a handful of sugar D) a piece of chocolate

She could have put a steel spoon into the vessel. The correct option is A.

Explanation:

When a candle wax is passed through heat, it is capable of melting within 10- 15 minutes of boiling. Therefore it is not capable of looking the same after 30 mins of heating.

When sugar is put into water it dissolves. When heated it has the ability to crystallize out after water is evaporated but doesn't retain its shape.

A piece of chocolate will melt the instance it comes in contact with any form of heat.

A steel spoon is an alloy metal which is not capable of melting by boiling in water for just 30 minutes. A steel is an alloy of Iron and carbon which melts when superheated at the temperature of 1510 degrees.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
