Question

Which meaterial had the largest change in final temp when 250j of energy were added? Cooper glass silver or wood

Answer 1

Silver, assuming all materials have equal mass.

Step-by-step explanation:

The equation relating q ("heat" energy) to temperature is
q = m * C *
`\delta` t
m = mass
C = heat capacity

`\delta` t = change in temp = delta t

Assuming the materials have the same mass, the material that would have the highest delta t would have the smallest heat capacity. This makes sense, as a high heat capacity would mean that the material can absorb lots of energy before only changing a small bit in temperature.

Wood and glass have heat capacities of about 1.7 and 0.7 each, respectively. Copper has a heat capacity of about 0.4, while silver has a heat capacity of about 0.2. This means that silver will change the most in temperature when 250 J of energy is added to each of the materials.
