Dr. Terror has developed a new alloy called Ultranomium. He is testing a bar that is 1.25 m1.25 m long and has a mass of 382 g.3

82 g. Using a carbon‑dioxide infrared laser, he carfully heats the bar from 20.6 ∘C20.6 ∘C to 288 ∘C.288 ∘C. Answer the two questions below, using three significant digits. Part A: If the bar absorbs 89300 J89300 J of energy during the temperature change, what is the specific heat capacity ( cc ) of the Ultranomium?

Answer:0.8742j/g°C

Explanation: SOLUTION

GIVEN

length of bar=1.25m

mass 382g

temperature= 20°C to 288°C

Q=89300J

Specific Heat Capacity  will be calculated using

Q=mC∆T

where

C = specific heat capacity

Q = heat

m = mass

Δ T = change in temperature

C=Q/ m∆T

=89300/382X(288-20.6)

=0.8742j/g°C
