Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
The chart is attached below and the options are as follow,
A Benzene
B Methanol
C Hexane
D Octane
Answer: Option-B (Methanol) is the correct answer.
Explanation: As we know that the substance given to student is soluble in water. Therefore, those substances which are soluble in water are
polar in nature because water is
polar in nature and
Like Dissolves Like.
Hence, in chart it can easily be seen that
Methanol is also polar in nature due to presence of -O-H (polar) bond. So, the substance will dissolve in it.
Answer:
a) water molecules move rapidly in the mug of boiling water while they move slowly in the ice water. In the ice itself, the molecules stay in place.
b) Water must release energy to move from a higher to lower energy phase, i.e., from gas (water) vapor to liquid during condensation and from liquid to solid (ice) during freezing. In each case, the energy released by the water results in a change in the internal molecular bonding structure.
Explanation:
Answer:
sublimation
Explanation:
the other choices release energy
Answer: 35 grams
Explanation: In sea water there is typically close to 35 grams of dissolved salts in each liter. It is written as 35 ‰ The normal range of ocean salinity ranges between 33-37 grams per liter (33‰ - 37‰). But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity.
