Description : Why a polystyrene cup is used instead of a glass beaker to find out heat of neutralization?
Last Answer : Ans: A polystyrene cup acts as an insulator therefore it will not allow heat to exchange between reaction mixture and its surroundings and enthalpy of reaction doesn’t change . On the other hand glass can easily transfer and exchange heat bringing change in enthalpy of reaction.

Description : Take a 250 mL beaker/glass tumbler. Fill half of it with water. Now carefully cut a small piece of sodium metal. Dry it using filter paper and wrap it in a small piece of cotton. Put the sodium piece wrapped in cotton into the beaker. Observe carefully. -Science
Last Answer : On touching the beaker, it was felt hot. The solution turns the red litmus paper to blue which shows it is basic in nature. Blue litmus paper do not show any colour change with the solution.

Description : When a cube of ice floating on water in a beaker melts, the level of water in the beaker (a) rises (b) falls (c) remains the same (d) first rises and then falls
Last Answer : Ans:(c)
Description : A piece of ice is floating in water kept in a beaker. When all the ice melts the level of water will - (1) first rise and then fall (2) fall (3) remain the same (4) rise
Last Answer : (3) remain the same Explanation: The submerged portion of the ice on melting shrinks a little in volume. So the level of water goes down a little. But this is just made up by the water added by the melting of upper portion.
Description : If an ordinary glass tube and a glass capillary tube are 'both clipped in a beaker of water, water rises in – (1) both (2) only the glass tube (3) only the capillary tube (4) neither
Last Answer : (1) both Explanation: The rise or fall of liquid due to capillarity in a beaker of water depends upon the radius of the bore of the tube (s) which is/are dipped into it. The narrower the bore of ... in the tube. So in this case, water will rise in both the glass tube and the glass capillary tube.
Description : Water contained in a beaker can be made to boil by passing steam through it (a) at atmospheric pressure (b) at a pressure below the firuosphejric pressure (c) at a pressure greater than atmospheric pressure (d) any pressure (e) not possible.
Last Answer : Answer : c
Description : If an ordinary glass tube and a glass capillary tube are both dipped in a beaker of water, water rises in (1) both (2) only the glass tube (3) only the capillary tube (4) neither
Last Answer : both
