When the temperature of a gas rises, the average energy of the particles increases. According to the Kinetic Molecular Theory, kinetic energy is proportional to its temperature. However, a rise in temperature doesn't directly double the energy.
The behavior of particles in a gas is very much affected by temperature changes. When the temperature of a gas increases, so too does the energy that the gas's particles have. This is defined by the Kinetic Molecular Theory, which states that the kinetic energy of a gas is proportional to its temperature. Therefore, when the temperature of a gas rises from 23°C to 46°C, the average energy of the particles increases. However, it doesn't double as an increase in temperature is not responsible for directly doubling the energy. Additionally, this increase in energy results in an increase in the velocity of the particles, but not necessarily by a factor of sqrt(2).

The gallbladder stores bile ( made in the liver) which is secreted into the digestive tract to aid in the digestion of dietary fats.
According to periodic trends, bismuth has the greatest atomic radius.
(2) 2 (4) 18
Answer: (3) 15
Explanation: We criss-cross down the oxidation numbers to get the subscripts for the correct formulas. That means the X has an oxidation number of 5. The element with the + oxidation number is always written first so it is +5. Of the groups names, only group 15 has +5 as an oxidation number.
Trigonal planar is the three-dimensional shape of the molecule with this Lewis structure. Hence, option C is correct.
Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule.
According to the Lewis structure of formic acid, the carbon atom is a central atom and it has three bond pairs without any lone pair of electrons. In VSEPR theory, the double bond is treated as one bond pair for the prediction of the shape of the molecule.
Hence, formic acid will have a trigonal planar geometry around the carbon atom and tetrahedral geometry around oxygen atom as it has two lone pair and two bond pairs
Hence, option B is correct.

The edge length of a a unit cell of calcium crystal is 509.12 pm.
Calcium crystal has a face center cubic (FCC) structure.
The edge length of the unit cell for face center cubic (FCC) structure is given in the following formula;
a = 2r√2
where;
a = 2 x 180 x √2
a = 509.12 pm
Thus, the edge length of a a unit cell of calcium crystal is 509.12 pm.

What conditions must be specified when expressing the solubility of a substance
Solubility means the ability of a solute to dissolve in solvent to form a solution.
The temperature and pressure must be specified when expressing the solubility of a substance.
Solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a particular temperature.
The solute can be a solid, liquid or a gas.
The solubility of a solid or a liquid solute in a solvent is affected by the temperature, while the solubility of a gaseous solute is affected by both the temperature and the pressure of the gas.
Temperature must be specified because solubility varies with temperature. For gases, the pressure must also be specified. Solubility is specific for a particular solvent.
Therefore, Solubility means the ability of a solute to dissolve in solvent to form a solution.
The temperature and pressure must be specified when expressing the solubility of a substance.
