During this simulation lab, we will be looking at different materials and seeing how their change in temperature is affected by changing the mass and how they are heated. We will also explore how specific heat changes when the mass or amount of time is changed.
Substance 1: Wood
During the video you will record the mass, change in temperature, and amount of heat applied.
Question 1
1.

When the mass of the wood was doubled, what happened to the change in temperature, when the amount of heat remained constant?
the change in temperature remained the same
the change in temperature was cut in half
the change in temperature doubled
When the mass of the wood was doubled, what happened to the specific heat, when the amount of heat remained constant?
the specific heat doubled
the specific heat remained the same
the specific heat was cut in half
When the mass of copper remained the same, but the amount of heat applied increased by 5x, what happened to the change in temperature of copper?
The change in temperature decreased
The change in temperature increased
The change in temperature remained constant
When the mass of copper remained the same, but the amount of heat applied increased by 5x, what happened to the specific heat of copper?
The specific heat remained constant
The specific heat increased by 5x
The specific heat decreased by 5x
Look at the two wood trials and two copper trials, does the specific heat of a specific substance change?
no
yes
Look at the first wood trial (250J and 5g) and the second copper trial (250J and 5g), which substance had the biggest change in temperature? Why?
Copper; because copper has a greater specific heat
