Which substance has the most energy, the brick or the water?
How can one substance have more energy than another if they are both the same temperature?
Use the slider to turn on the heat. Which substance heats up the quickest.
Which substance requires the most energy to change its temperature 1 degree?
Assume that the brick and the water have the same mass. Which substance has the highest heat capacity?
Design an experiment using the simulation to determine whether the iron or the brick has the highest heat capacity. Be sure to describe your procedure. The evidence that you obtained and then explain how that evidence supports your conclusion. For full points, you must use the definition of heat capacity in your explanation.
All solids, liquids and gasses have a specific heat capacity. In the heating curve below, we are starting with a sample of ice from that very cold ridge in Antartica. Label each part of the curve with the correct name for the energy being absorbed between the two points.
Compare the heating curves of these two substances and then chose the substance for which each of the following is true.
Substance 1 | Substance 2 | |
|---|---|---|
Lowest Melting Point | ||
Lowest Boiling Point | ||
Lowest Heat Capacity | ||
Most temperature change for 1 unit of heat | ||
Requires most heat to melt | ||
Requires most heat to change temperature of liquid |
1. Click on the Systems Box.
2. Select the Pipe and the generator and the water.
3. Click on the box for the energy symbols.
If you have it set up correctly, it should look like this.
Open the pipe and watch the energy flow, it should look like this
Watch the simulation and then use your observation to fill in the statements below.
The of the water is high when it is in the pipe because the water is attracted to the earth. As the water falls, the of the water is converted to . The of the water is converted to which is used to turn the wheel. When the right-hand side of the wheel moves it goes from a position with potential energy to a position with potential energy.
The energy entering the water is which is converted to which increases the of the particles in the system and which reduces the between the particles.
An example of energy flowing into the system is the energy blocks being transferring from the to the .
An example of energy flowing out of the system is the energy blocks being transferred from the to the .
When the temperature of the water is constant, the number of energy blocks entering the water in the container is the number of energy blocks leaving the containing.
Click on the spot where the thermal energy is being transformed to mechanical energy.
Play with the simulation by changing the sources of energy and the mechanisms of transfer.
What is an example of energy being transferred using radiation?
Play with the simulation by changing the sources of energy and the mechanisms of transfer.
What is an example of energy being transferred using conduction?
If the air above the ice is at -90°C and the ice is not melting how cold is the surface of the ice?
