Answer:
The water will continue to heat up as the experiment progresses.
Explanation:
When a person's fingers are cold or has a muscles ache, one can use chemical hand warmers to heat them up. There are two types of chemical hand warmer products, and they all depend on exothermic chemical reactions to work.
However, ammonium chloride dissolution is endothermic but its crystalization is exothermic. When used as a hand warner with a calorimeter, it is found that the temperature of the water increases steadily due to the crystalization of the ammonium chloride. Hence the answer.
Answer:
B
Explanation:
it flows by the conduction currents
Explanation:
- An ionic compound is defined as the compound formed by transfer of electrons from one atom to another.
For example, lithium atom on donating its one valence electron to chlorine atom will result in the formation of an ionic bond and the compound formed is LiCl.
- A molecule is defined as a substance which can contain either same or different elements.
For example, 
, 
etc are molecules.
- A molecule can contain either a covalent or ionic bond. But an ionic compound will always contain an ionic bond.
