This is covalent network type of solid.

For example, silicon dioxide (SiO₂) is covalent network solid with covalent bonding.

Covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.

Silicon(IV) oxide has continuous three-dimensional network of SiO₂ units and diamond has sp3 hybridization.

This solids do not have free electrons so they are good insulators.

They have strong covalent bonds, so they melt at extremely high temperature.

Other examples are quartz, diamond, and silicon carbide.

If 1.10 g of steam at 100.0 °C condenses into 38.5 g of water, initially at 27.0 °C, in an insulated container, what is the fina
Gwar [14]

Answer:

Temperature = 44.02°C

Explanation:

Insulated container indicates no heat loss to the surroundings.

The specific heat capacity of a substance is a physical property of matter. It is defined as the amount of heat that is to be supplied to a unit mass of the material to produce a unit change in its temperature.

The SI unit of specific heat is joule per kelvin and kilogram, J/(K kg).

Now,

Specific heat for water is 4.1813 Jg⁻¹K⁻¹.

Latent heat of vaporization of water is 2257 Jg⁻¹.

Energy lost by steam in it's process of conversion to water, is the energy acquired by water resulting in an increase in it's temperature.

Q = mS \Delta T

Q= Heat transferred

m= mass of the substance

T= temperature

Also,

Q = mL

L= Latent heat of fusion/ vaporization ( during phase change)

Now applying the above equations to the problem:

m_{w} S_{w} (T-27) = (m_{s} L) + m_{s}S_{w} (100 -T)

38.5 \times 4.1813 \times (T-27) = (1.10 \times 2257) + 1.10 \times 4.1813 \times (100 -T)

Temperature = 44.02°C

How much heat is released when 345 g of tin is cooled from 210.0 degrees * C to 0.0 C? (C= 0.220 J/gC)
Ne4ueva [31]

Answer: 18634 joules

Explanation:

The quantity of Heat Energy (Q) released when a heated substance is cooled depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of oil = 345g

C = 0.220 J/g°C

Φ = (Final temperature - Initial temperature)

= 0°C - 220°C = -220°C

Then, Q = MCΦ

Q = 345g x 0.220 J/g°C x -220°C

Q = 18634 joules (note that negative sign will not reflect in answer, because it only indicates that heat was released rather than gained)

Thus, 18634 joules of heat is released
