Question

1. using words and/or drawings, complete the graphic organizer. indicate the cause and effect of the relationship between a) the addition of thermal energy to a substance and b) the change in average kinetic energy of particles in the substance. cause and effect

Explanation:

Step1: Identify the cause

The cause is the addition of thermal energy to a substance. This is because thermal energy is being supplied to the system, which initiates a change.
Thermal energy is added to the substance.

Step2: Determine the effect on particle kinetic - energy

When thermal energy is added to a substance, the average kinetic energy of the particles in the substance increases. This is because thermal energy is related to the motion of particles. As more energy is added, particles move faster on average.
The average kinetic energy of particles in the substance increases.

Step3: Describe the mechanism

The mechanism is that the added thermal energy is transferred to the particles as kinetic energy. The heat causes the particles to vibrate, rotate, and translate more vigorously.
Thermal energy is transferred to particle kinetic energy, increasing particle motion.

Answer:

Cause: Thermal energy is added to the substance.
Effect: The average kinetic energy of particles in the substance increases.
Mechanism: Thermal energy is transferred to particle kinetic energy, increasing particle motion.
