why is iron almirah solid at room temperature?
393682
(b) An iron almirah is a solid at room temperature because its melting point as well as boiling point is above room temperature. ... Hence, iron almirah is a solid at room temperature.

Ionic Solid Ionic solids tend to have high melting points ("high" generally being higher than metallic but lower than covalent). Because the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids.

Group 8A crystalline solids are a specific variety of atomic crystalline solids. They are comprised of solidified, inert noble gases [such as neon (Ne), argon (Ar), helium (He) and radon (Rn)], and can only occur at incredibly low (near absolute zero) temperatures.

FePO4 is a yellow brown solid at room temperature. It is insoluble in water. Its melting point is 250 ̊C (482 ̊F) and density is 3.056 g/cm3. ... The chemical name of FePO4 is iron(III). You may also call it ferric phosphate.

1) as almirah is a solid, so it has a definite shape and volume. so it is solid at room temperature. 2) the melting point of iron is very high (1538°) while the room temperature is 28°. as melting point of iron is very high as compared to room temperature, it is solid at room temperature.

Physical Properties of Metals State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field. Magnetic materials consist of atoms with partially-filled electron shells.

The alkali metals are solids at room temperature (except for hydrogen), but have fairly low melting points: lithium melts at 181ºC, sodium at 98ºC, potassium at 63ºC, rubidium at 39ºC, and cesium at 28ºC. They are also relatively soft metals: sodium and potassium can be cut with a butter knife.

Iron, a solid at room temperature, becomes a liquid at 2800 degrees Fahrenheit (really, REALLY hot) and a gas at 5182 degrees Fahrenheit (about half the temperature of the sun).

Physical and Chemical Properties Iron, like other metals, conducts heat and electricity, has a luster, and forms positive ions in its chemical reactions. Pure iron is fairly soft and can easily be shaped and formed when hot. Its color is silvery white. Iron is easily magnetized.

Ionic solid have high vapor pressures because they have very strong intermolecular forces holding the molecules together in a crystalline structure.

Ionic solids are very hard and brittle. ... Brittle since when distorted like charged ions move closer to each other and the strong electrostatic repulsions shatter the crystal.

An example of an ionic solid is table salt, NaCl. Molecular solids—Made up of atoms or molecules held together by London dispersion forces, dipole-dipole forces, or hydrogen bonds. Characterized by low melting points and flexibility and are poor conductors.
