Question

marsha is investigating how convection works while heating a pot of soup. materials: a can of soup, stove top with electric burner, and a 1 - quart pot. procedure: 1. marsha emptied the contents of the soup can into the pot. 2. she switched on the stove. 3. she placed the soup pot on the stove. 4. as the soup heats, the particles at the bottom of the pot move faster, become less dense and rise to the top. which statement best describes what happens as the soup is heated? oa the less dense particles move upwards and create a convection current. lighter cool particles at the top move to the bottom and heavier warm particles at the bottom rise to the top. ob the less dense cool soup rises upwards while the heavier warm soup particles sink downwards. this sets up a convection current as the cooler particles rise and warmer particles sink. oc the cooler denser particles at the top of the soup sink. the warmer less dense soup moves upwards and completes a convection current. cooler soup at the top moves to the bottom and warms up while the warmer soup at the bottom moves to the top and cools. od the cooler denser particles at the bottom of the soup sink. the less dense soup moves upwards and creates a convection current. cooler soup at the bottom moves to the top and warms up while the warmer soup at the top moves to the bottom and cools.

Explanation:

Convection occurs when warmer, less - dense fluid rises and cooler, denser fluid sinks. In the case of heating soup, the warmer, less - dense soup at the bottom rises, and the cooler, denser soup at the top sinks, creating a convection current.

Answer:

C. The cooler denser particles at the top of the soup sink. The warmer less dense soup moves upwards and completes a convection current. Cooler soup at the top moves to the bottom and warms up while the warmer soup at the bottom moves to the top and cools.
