Heat energy is needed for evaporation to happen.
Here is what radioactive decay is:
<span>Radioactive decay is the spontaneous breakdown
of an atomic nucleus resulting in the release of energy and matter from
the nucleus. Remember that a radioisotope has unstable nuclei that does
not have enough binding energy to hold the nucleus together.</span>

Explanation:
Landon glances across the dinner table and thinks to himself that his fathers curly hair looks just like his own. He wishes his hair were straight like his mothers because he thinks he looks better with straight hair. Landon works hard to keep it straighter by combing and using hair gel, but it usually curls right back up. He has his mothers nose, but not her hair, unlike his sister Emily, who is also the result of the combination of the DNA from both of his parents and has straight hair like their mothers. Most eukaryotic organisms, like Landon, are formed through the process of sexual reproduction. Landon realizes that he and Emily are evidence that sexual reproduction, the combination of their two parents, creates diverse offspring.
Landons dinner plate is filled with one of his favorite foods-mashed potatoes made from potatoes fresh from his grandmothers garden. He remembers helping her get ready to plant the potatoes in early spring. They cut each potato into several pieces and planted the pieces in a nice straight row in the garden. When these eukaryotic plants came up, he noticed that each plant looked like all the others. These identical offspring with uniform traits are the result of asexual reproduction. Landons grandmother grew potatoes by cutting the whole potato into smaller pieces, which is a type of asexual reproduction called vegetative propagation.
After dinner, Landon wanted to go watch television, but his mother insisted that he put the leftover food in the refrigerator. Perhaps she knew that the cool temperature inside the refrigerator would stop the growth of bacteria, which are prokaryotic and can reproduce asexually in as little as 20 minutes. This rapid asexual reproduction, called binary fission, would produce thousands and thousands of identical bacterial cells that could cause Landons tasty leftover food to spoil before the end of his favorite show.
Landon finishes up the dishes and puts away the leftovers. As he sets the last dinner glass back into the cupboard, he catches a glimpse of his curly hair in his reflection. He thinks to himself that his mothers nose and his fathers hair are actually a good combination that looks pretty good on him
Answer:
The unit cell edge length for the alloy is 0.405 nm
Explanation:
Given;
concentration of Ag, 
= 78 wt%
concentration of Pd, 
= 22 wt%
density of Ag = 10.49 g/cm³
density of Pd = 12.02 g/cm³
atomic weight of Ag, 
= 107.87 g/mol
atomic weight of iron, 
= 106.4 g/mol
Step 1: determine the average density of the alloy
Step 2: determine the average atomic weight of the alloy
Step 3: determine unit cell volume
for a FCC crystal structure, there are 4 atoms per unit cell; n = 4
Step 4: determine the unit cell edge length
Vc = a³
= 0.405 nm
Therefore, the unit cell edge length for the alloy is 0.405 nm
Answer:
Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
