Question

ivan was assigned to design an investigation to explore how thermal energy transfers between two objects at different temperatures. the objects are placed together in a closed, insulated container. which step would help him examine how the energy distribution changes over time? check and note the temperatures at the start and end without taking additional readings. measure the temperature of both objects every minute to track their changes over time use an open container and observe the temperature changes in each object over time record the initial temperatures and check again after 60 minutes for any changes

Explanation:

To examine how energy distribution changes over time, continuous tracking of temperature changes is needed. Measuring the temperature of both objects every minute allows for observing the gradual changes in energy distribution as heat is transferred. Using an open - container would introduce external heat exchange, and checking only at the start and end or at long intervals (like 60 minutes) won't show the continuous change.

Answer:

Measure the temperature of both objects every minute to track their changes over time
