Question

Heat, also called thermal energy, can be transmitted through space (radiation), by moving fluids (convection), or through direct contact. This final method, called conduction, is explored in the Heat Transfer by Conduction Gizmo. To begin, check that Aluminum is selected. Select the BAR CHART tab and turn on Show numerical values. What is the initial temperature of each beaker? Beaker A * 0 degrees C 5 degrees C 25 degrees C 50 degrees C 75 degrees C 95 degrees C 100 degrees C Beaker B * 0 degrees C 5 degrees C 25 degrees C 50 degrees C 75 degrees C 95 degrees C 100 degrees C (pick one answer for each beaker)

Answer 1

Beaker A: Initial temperature is 100 degrees C
Beaker B: Initial temperature is 0 degrees C

Answer 2

What happens to the temperature of Beaker A over time?

The temperature decreases over time.
The temperature increases over time.
No change in temperature

Answer 3

The temperature of Beaker A decreases over time.

Answer 4

What happens to the temperature of Beaker B over time?
*
The temperature decreases over time.
The temperature increases over time.
No change in temperature

Answer 5

The temperature of Beaker B increases over time.

Answer 6

Why do you think the temperatures of Beaker A and Beaker B changed as they did?
*
Thermal energy is transferred from Beaker B to Beaker A via conduction.
Thermal energy is transferred from Beaker B to Beaker A via convection.
Thermal energy is transferred from Beaker A to Beaker B via conduction.
Thermal energy is transferred from Beaker A to Beaker B via convection.
There was no change
Other:
(if Other write your response)

Answer 7

Thermal energy is transferred from Beaker A to Beaker B via conduction.
