When water molecules freeze A) they experience greater attractive forces because they have less energy when cold

B) they join with chemical bonds to other water molecules

C)they gain more electrons and experience strong Coulomb's Forces.

Dthe chemical bonds break, and they become charged particles

A) they experience greater attractive forces because they have less energy when cold

Explanation:

Freezing happens when the molecules of a liquid get so cold that they slow down enough to hook onto each other, forming a solid crystal. For pure water, this happens at 32 degrees Fahrenheit, and unlike most other solids, ice expands and is actually less dense than water.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

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.
