Question

using fig. 2, select the graph that best represents the relationship between particle energy and substance temperature as the cylinder is heated.

Explanation:

When a substance is heated, the energy of its particles increases. As particle energy increases, the temperature of the substance also increases. Graph B shows a positive relationship where as particle energy goes up, temperature goes up. Graph A shows a negative relationship (as particle energy increases, temperature decreases) which is incorrect for a heating scenario.

Answer:

B.
