the most appropriate
kinetic energy gof molecules at roomtemprature gis miniuum in
- carbon dioxide
The correct answer is 1) wood. This is because wood is a solid, while helium and carbon dioxide are gases and alcohol is a liquid. We know that inter-particles spaces are minimum in solids and maximum in gases. Thus, particles in a solid are closely packed and hence do not move freely. So, the kinetic energy of molecules at room temperature is minimum in wood (a solid).
