Which contains more molecules of water. 5 liters of ice at 0 degrees Celsius or 5 liters of water at 0 degrees Celsius?

5 grams of water will have more water molecules since ice had 1.67 x molecules and 5 gm ice had 1.53 x 10 molecules of water.

Explanation:

5 liters of water at 0 degrees or 273.15 K will have, Formula used is:

number of water molecules = x Avagadro number

Avagadro number = 6.022 X 10 ^23 molecules or atoms in 1 mole

atomic mass of 1 mole water = 18.01 grams/mole

putting the value in the equation:

number of molecules = x 6.022 x 10^23

number of molecule of water in water =  1.67 X molecules.

5 gm cm^3 of ice will have

The density of ice = 0.917 gm/cm^3

volume = density x mass

number of moles of water = x Avagadro number

putting the values,

number of moles in ice = X 6.022 X 10^23

                                       = 1.53 X molecules of water

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
