The triple point of a substance is the temperature and pressure at which the substance exists as which of the following?
Simultaneously in sol, gel, and plasma phases
As a gel with solid and liquid trapped in gas
As a sol with gas and solid trapped in liquid
Simultaneously in solid, liquid, and gas phases
The Correct Answer is D
The triple point of a substance is the temperature and pressure at which the substance exists simultaneously in solid, liquid, and gas phases ¹. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium ¹.
The other options are not correct because they do not accurately describe the triple point of a substance. Sol, gel, and plasma are not phases that coexist at the triple

Nuclei. Genetic information describing the characteristics of an organism is found in the nuclei of its cells. The nucleus contains the organism's DNA, which carries the genetic information that determines its traits.
B. Membranes are structures that surround and enclose cells and organelles, but they do not contain genetic information.
C. Cilia are hair-like structures that protrude from the surface of some cells and are involved in movement, but they do not contain genetic information.
D. Ribosomes are organelles that are involved in protein synthesis, but they do not contain genetic information.
Correct Answer is A
Explanation
A chloride ion has a negative charge because it gained an electron. When an atom gains an electron, it becomes negatively charged because it now has more electrons than protons. In the case of a chloride ion, the neutral chlorine atom gains an electron to become a negatively charged chloride ion.
The other options are not correct because they do not result in a negative charge. Losing an electron would result in a positive charge. Losing or gaining a proton would change the identity of the atom and is not related to the formation of a chloride ion.
