3350 J of heat is required to raise the temperature of a sample of AlF3 from 250C to 800C. What is the mass of the sample?
1 answer:
Answer:
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
Explanation:
The formula for for the heat (q) absorbed by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample. and
ΔT = the change in temperature
1. What you must do
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
2. Sample calculation
For this example, I assume that the specific heat capacity of AlF₃ is 1.16 J·K⁻¹mol⁻¹
.
(a) Calculate ΔT
(b) Calculate m
