1. The problem statement, all variables and given/known data According to the kinetic molecular theory: as the distance between the molecules increases, the temperature of a material decreases the rise in temperature of a material occurs because the molecules lose kinetic energy when the molecules within a gas collide they lose energy, reducing the temperature of the gas the molecules within all liquids and gases are always in motion, but not in solids. 2. Relevant equations 3. The attempt at a solution I said 4 because liquids and gases have translational energy while solids dont. However, the answer is 1. Can someone explain how does the distance between molecules affect temperature? Cheers!
