Question: Can the speed of a given molecule in a gas double at constant temperature? Explain your answer.

Short Answer

Expert verified

Yes, the speed of a given molecule in a gas doubles at constant temperature due to internal collisions.

Step by step solution

01

Concept Introduction

A molecule is a group of two or more atoms bound together by chemical bonds.

02

Speed of a Molecule

Yes, in a chamber that contains a sample of a gas, the speed of the gas molecules can double at time (or) reduce at any time, at constant temperature or without providing any other external energy.

This is possible due to the internal collisions between the gas molecules and with a container鈥檚 walls, which can lead either to increase the speed (or) to decrease the speed of the gas molecules.

Therefore, the speed of a given molecule in a gas doubles at constant temperature due to internal collisions.
