Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures.
Greg is a scientist working in a lab with a specific metal. The metal is being kept in different storage containers. The containers are all different temperatures, and Greg has misplaced the exact temperature each container is set at unfortunately. All he can go by are his observations. The metal in the Red Box is in liquid form, and the metal in the Blue Box is in a solid form.
Does the Red Box have a higher or lower kinetic energy than the Blue Box?
