The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. Which best describes this statement? This is a limitation of the kinetic-molecular theory. This is a postulate of the kinetic-molecular theory. This describes ideal gas behavior using the kinetic-molecular theory. This describes ideal gas behavior without the kinetic-molecular theory.

This is a limitation of the kinetic-molecular theory. Hence, option A is correct.

Strong intermolecular force is defined as the increase in viscosity of the liquid, increase in surface tension, decrease in vapour pressure, and an increase in the boiling point while weak intermolecular forces define as the decrease in viscosity, a decrease in surface tension, an increase in vapour pressure, and an increase in boiling point.

The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures which is a limitation of the kinetic-molecular theory.

Hence, option A is correct.

The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. This is a Limitation of the Kinetic Molecular Theory. Hence Opton (A) is correct.

According to the kinetic molecular theory, the average kinetic energy of gas particles is proportional to the absolute temperature of the gas.

The kinetic theory of gases is a simple, historically significant classical model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established.

Therefore, The closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. This is a Limitation of the Kinetic Molecular Theory. Hence Opton (A) is correct.

An investigator proposes a study to determine the clinical relevance of a new assay technique to measure minimal residual disease (MRD) in adolescent (age 14-16) cancer patients undergoing chemotherapy. The study requires that two additional bone marrow aspirates be performed during the course of chemotherapy. The subject's chemotherapy will not be altered based on the results of the assay technique measures. However, future patients with cancer would benefit from improved interventions based on study findings. The IRB determined that the activity was a minor increase over minimal risk. Which of the following statements best describes the IRB approval requirements for involving adolescent cancer patients in the research study?

Assent is not required, however, both parents must give permission for the inclusion of the adolescent child.
Assent of the child only is required.
Assent is not required, however, one parent must give permission for the inclusion of the adolescent in this study.
Assent of the child and permission of both parents are required.
