Step-by-step explanation:
Scientists use a bell curve (also known as a normal distribution) to describe temperature or the rate of change of particles because it provides a visual representation of the distribution of data around the average or mean value. The bell curve shape is symmetrical around the mean, with the majority of the data points clustering around the mean and fewer data points further away from the mean.
In the case of temperature, the mean temperature represents the average temperature of a sample, and the shape of the bell curve indicates how much the temperature deviates from the average. The use of a bell curve helps to show any patterns or trends in the data and can be used to make predictions about future temperature changes based on past observations.
Similarly, in the case of particle motion, the mean velocity represents the average speed of the particles, and the bell curve shows how the speed of the particles is distributed around the mean. The use of a bell curve helps to understand the behavior of particles and the distribution of energy among particles in a system.
