What is the melting point for naphthalene?

80.26 °C
Naphthalene/Melting point

Is there a temperature change as naphthalene is melting?

If heat is then added to naphthalene, it will melt until it reaches 80o C and it will stay at that temperature until melting is complete. This would be the melting point of naphthalene. After melting is complete, the temperature will begin to rise again until it reaches 218o C.

What is the molecular formula for naphthalene?

C10H8
Naphthalene/Formula

What will happen if naphthalene balls are heated?

As the naphthalene is heated, heat energy is converted to kinetic energy. Kinetic energy increases and the molecules vibrate faster about their fixed positions and the temperature increases. Naphthalene is in solid state at any temperature below its melting point. The particles can only vibrate at a fixed position.

Is naphthalene poisonous to humans?

Inhalation of naphthalene may cause skin and eye irritation; gastrointestinal symptoms, such as nausea, vomiting, abdominal cramps, and diarrhea; neurologic symptoms, such as confusion, excitement, and convulsions; renal problems, such as acute renal shutdown; and hematologic features, such as icterus and severe anemia …

What happens to the temperature of naphthalene during melting?

As the naphthalene is heated, heat energy is converted to kinetic energy. Kinetic energy increases and the molecules vibrate faster about their fixed positions and the temperature increases. Naphthalene is in solid state at any temperature below its melting point.

What will happen if heat is given to camphor?

When camphor is heated then it will not be converted to liquid state, but it will be directly converted to gaseous phase. this is called sublimation. also when you bring flame near to the camphor it catches fire and burns.

Can we burn naphthalene balls?

Naphthalene is a white solid that evaporates easily. It is also called mothballs, moth flakes, white tar, and tar camphor. When mixed with air, naphthalene vapors easily burn. Fossil fuels, such as petroleum and coal, naturally contain naphthalene.

Can I use naphthalene balls in toilet?

use for Bathroom, Napthalene Balls repelling or killing insects such as moths and silverfish. Controls bad order in toilets and wash rooms. Naphthalene Balls are exteusively used for keeping products bacteria free. They can also be used around sinks & wash basins to keep the foul smell away.

How harmful is naphthalene?

Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage. Cataracts have also been reported in workers acutely exposed to naphthalene by inhalation and ingestion.

What happens if we heat naphthalene?

When heated at 80 °C, napthalene rapidly sublimes directly from a solid into a gas, eventually leaving nothing remaining in the crucible. On cool surfaces, the gaseous naphthalene will re-solidify to form needle-like crystals. This process is a method of purifying napthalene.

What is the boiling point of naphthalene?

Pure naphthalene melts at 80.2 C; the less pure forms of the compound will melt at temperatures ranging from 74 to 80 C. The boiling point of naphthalene is 217.96 at atmospheric pressure (Manufacturing Chemists Assoc. 1956).

Is Napthalene a compound or mixture?

Naphthalene is an organic compound with formula C 10 H 8.It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene’s structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs

What is the point group of naphthalene?

The point group symmetry of naphthalene is D2h . Pure crystalline naphthalene is a moderate insulator at room temperature, with resistivity of about 10 12 Ω m. The resistivity drops more than a thousandfold on melting, to about 4 × 10 8 Ω m.

What is the density of naphthalene?

The density of the chemical compound Naphthalene is 1.14 grams per cubic centimeter
