Description : As the temperature of ice rises, the ice melts and its density _____. A. Decreases B. Remains constant C. Increases D. Increases upto 10 °C
Last Answer : ANSWER: C
Description : Which have the maximum density? (1) Water (2) Benzene (3) Ice (4) Chloroform
Last Answer : (1) Water Explanation: Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less than 1 g/cm3.
Description : Ice float on water because its density is (1) more than water (2) less than water (3) zero (4) same as water
Last Answer : (2) less than water Explanation: Archimedes' Principle states that for an object to floaton water, it must displace an equal amount of water. Ice floats because it is about 9% less dense than liquid water.
Description : Explain the following (a) The density of ice is less than that of liquid water? (b) The boiling point of water is less than that of H2S. (c) NaH has higher reducing character than H2O.
Last Answer : Ans-a) In structure of ice , Oxygen atom is tetrahedrally surrouneded by four hydrogen (with two hydrogen by hydrogen bond and with two hydrogen by covalent bond ) and have vacant spaces in ... Due to extensive hydrogen bonding in water c)NaH is ionic compound while water is a covalent compound
Description : As the temperature of ice rises, the ice melts and its density? A. Decreases B. Remain constant C. Increases (Answer) D. Increases upto 10C
Last Answer : C. Increases (Answer)
Description : For which one of the following is the density maximum? A. Ice B. Water (Answer) C. Benzene D. Chloroform
Last Answer : B. Water (Answer)
Description : Density of Ice is-----? A. 800kg/m3 B. 917kg/m3 (Answer) C. 930kg/m3 D. 1000kg/m3
