112°C is 385.15 Kelvin
geniusboy [140]2 years ago
4 0

Answer:

112 °C = 385 K

Explanation:

The relation between Kelvin and Celsius degrees is

0°C = 273.15 K

To convert the temperature from Celsius to Kelvin we must add 273.15:

112 °C + 273.15 = 385.15 K

With the correct significant figures the answer would be 385 K

Elemental iodine (I 2) is a solid at room temperature. What is the major attractive force that exists among different I 2 molecu
Ulleksa [173]

Explanation:

As I_{2} is a covalent compound because it is made up by the combination of two non-metal atoms. Atomic number of an iodine atom is 53 and it contains 7 valence electrons as it belongs to group 17 of the periodic table.

Therefore, sharing of electrons will take place when two iodine atoms chemically combine with each other leading to the formation of a covalent bonding.

Hence, weak forces like london dispersion forces will be present between a molecule of I_{2}.

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

thus, we can conclude that london dispersion force is the major attractive force that exists among different I_{2} molecules in the solid.

What element glows in sign's when excited
ser-zykov [4K]

Answer:

The element that glows in signs is xenon.

Explanation:

Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts. Xenon is used in flash lamps, arc lamps, and as a general anesthetic. Xenon emits a blue or lavenderish glow when excited by electrical discharge, it emits a band of emission lines that span the visual spectrum, but the most intense lines occur in the region of blue light, producing the coloration.

Use the following picture to answer questions #6 and 7. Consider that after the snowboarder starts down from the hill from point
STALIN [3.7K]
Remeber:

Kinectic energy = [1/2]mv^2
Potential energy = m.g[h - h0]

6. When the snowboarder is still at the top, she does not have kinetic energy, given that the speed is zero.

There, at the top, the potential energy is maximum, given that the height, h - h0, is the highest.

So, ar the topo she only has potential energy.

7. From that point, the snowboarder, starts to gain velocity; is has started a process of conversion of potential energy to kinetic energy. More velocity, less height, more kinetic ener energy and less ptential energy.

At the very bottom, when she has reached the heigth of reference, h0, the term [h - h0] becomes zero, then the potential energy has dissapeared and all the energy has been transformed into kinetic energy; the speed and the kinetic energy are maximum.

Anvisha [2.4K]
The specific heat<span> is the amount of </span>heat<span> per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.</span>
