Answer:
When in direct contact, the fast-moving molecules in the radiator collide with the slow-moving molecules in the ice cube. Kinetic energy is transferred from the molecules in the radiator to the molecules in the ice cube, causing a slowdown of the radiator molecules and an acceleration of the ice molecules.
Explanation:
Answer: d. smaller.
Explanation:
Hybridization :
![N=\frac{1}{2}[V+N+A-C]](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN%2BA-C%5D)
N = number of electrons
where, V = number of valence electrons present in central atom i.e. oxygen = 6
N = number of monovalent atoms bonded to central atom=32
C = charge of cation = 0
A = charge of anion = 0
The number of electrons is 4 that means the hybridization will be
and the electronic geometry of the molecule will be tetrahedral. The bond angle for tetrahedral geometry is 
But as there are two atoms around the central oxygen, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent and the bond angle will be smaller than expected and is 
Answeeeeer:
A. cell
Explanation:
Since A is the smallest in the chart, that would correspond to the cell because thats the smallest out of Tissue, Organ and Organism.
