A liquid substance, like pure water, absorbs heat energy at room temperature.
Which of the following BEST describes what happens to the substance at a particulate level?
The particles in the substance begin to move faster in terms of rotational movement, causing an instantaneous increase in temperature.
The particles in the substance absorb the energy, resulting in more vibrational energy, which causes the temperature of the system to instantaneously increase.
The particles in the substance show a higher rate of translational energy due to the instantaneous change in temperature.
The particles in the substance absorb the initial energy in the form of heat and show no instantaneous sign of temperature change.
