2. If an object has a low specific heat, would it be more like a conductor or an insulator? Explain.
Can you please do only 4. thank you
The specific heat of substance C is 0.93 J/(g K) and that of substance D is 1.8 J/(g K).
You are given an unknown that could be pure substance C, pure substance D, or a homogeneous mixture of C and D. In the lab you determine that it requires 23.3 J of heat energy to raise the temperature of a 25.0 g sample of the unknown by 1.0 K. What conclusions can you make about the identity of your unknown, from this data?

Group of answer choices No; the specific heat calculated is lower than it should be due to the heat lost Yes; the specific heat calculated is lower than it should be due to the heat lost No; results will not be affected since the calorimeter contains all heat indefinitely Yes; results will not be affected since the calorimeter contains all heat indefinitelyarrow_forward
