To be able to do the experiment, and like that being able to find the correct answer to your hypothesis by testing it.
Answer:
(c) 2
Explanation:
Heat transfer across the walls due to conduction is given by:
where,
q = heat transfer rate
K = thermal conductivity
A = Area
ΔT = change in temperature
L = thickness
For wall A:
For wall B:
Because the change of temperature and area of walls are the same. Dividing both terms:
using values given in the question:
Therefore, the correct answer is:
<u>(c) 2</u>
K2C03 is Potassium Carbonate. It's a molecule.
